WATER RESOURCES OF HAWAII, 1913.

By G. K. LARKISON.

ATTTHOKITY FOB INVESTIGATIONS.

This volume contains results of measurements of the flow of certain streams and ditches and rainfall records of the Territory of 

Hawaii made during the calendar year 1913. The investigations 

leading to the report were made by the United States Geological 

Survey in cooperation with the Territory of Hawaii, under the general 

sanction of the organic law of the Survey (Stat. L., vol. 20, p. 394), 

which contains the following paragraph:

Provided, Thet this officer [the Director] shall have the direction of the geological 

survey and the classification of public lands and examination of the geological structure, mineral resources, and products of the national domain.

As water is the most abundant and most valuable of the minerals, 

the investigation of water resources is authorized under the provision 

for examining mineral resources. The work has been supported since 

the fiscal year ending June 30, 1895, by appropriations in successive 

sundry civil bills passed by Congress under the following item:

For gaging the streams and determining the water supply of the United States, and 

for the investigation of underground currents and artesian wells, and for the preparation of reports upon the best methods of utilizing the water resources.

The legislature of the Territory of Hawaii approved on March 22, 

1909, "An act to promote the conservation and development of the 

natural resources of the Territory," which provided in substance as 

follows: A special tax of 2 per cent shall be levied, assessed, and collected annually on all incomes in excess of $4,000; and all amounts 

so collected shall constitute a special fund to be expended only for 

the encouragement of immigration and the conservation of natural 

resources in the proportion of three-fourths for immigration and onefourth for conservation. The conservation fund shall be used for the 

development, conservation, improvement, and utilization of the natural resources, and shall be available for expenditure at such times 

and in such manner as a board of three persons appointed in accordance with section 80 of the organic act shall, with the approval of the 

governor, determine.

8 .WATER RESOURCES OF HAWAII, 1913.

An act of April 26, 1911, amended the original act so as to extend 

it until December 31, 1913.

On April 4, 1913, the governor of the Territory of Hawaii approved 

the following acts providing (act 56) for the creation and maintenance 

of a division of hydrography under the board of agriculture and 

forestry, and (act 57) appropriating the revenues from water licenses 

for the use of the board of commissioners of agriculture and forestry 

toward forest protection and hydrographic surveying.

Section 1 of act 56 reads:

The board of agriculture and forestry is hereby authorized to create and maintain 

a division of hydrography for the investigation and determination of the water resources of the Territory by the gaging of streams and rainfall and other means, in 

cooperation with the United States Geological Survey or otherwise, and in furtherance thereof to take over and exercise the functions of the Territory in the conduct of 

the present hydrographic survey of the Territory.

Section 2 provides that this act shall take effect on July 1, 1913. 

Section 1 of act 57 reads:

All revenues derived from water licenses, issued by the Territory, during the period 

beginning July 1, 1913, and ending June 30,1915, whether by way of rentals or otherwise, shall constitute and be held as a special fund in the treasury of the Territory 

to be disbursed on warrants of the auditor issued on approved vouchers of the president of the board of commissioners of agriculture and forestry. Such moneys shall be 

apportioned and applied from time to time by the board of commissioners of agriculture and forestry, acting with the approval of the governor, equally between the 

division of forestry and the division of hydrography to the following general purposes, 

and not otherwise:

1. For the protection of forest reservations, established or set apart according to 

law, against damage by fire, animals, and otherwise by means of fences and any other 

means whatsoever, and for the expenditures of the division of forestry.

2. For the development and maintenance of the hydrographic survey throughout 

the Territory.

Each voucher against said fund shall designate the general purpose for which it 

is drawn.

Section 2 provides that this act also shall take effect on July 1, 1913. 

COOPERATION.

Under the authority conferred by the Federal and Territorial 

legislation, the Director of the United States Geological Survey and 

the governor of the Territory of Hawaii entered into a cooperative 

agreement, dating from July 1, 1910, for "the gaging of streams and 

the determination of the water supply of the Territory of Hawaii." *

The principal features of this agreement are: :

1. The United States Geological Survey assumes the responsibility 

of gathering, analyzing, and publishing the data. ;

2. During the progress of the work all notes, maps, and data gathered as a result of field studies are at all times open to inspection by

several islands. The whole of the island of Kauai and a part of the island of Hawaii have been mapped.

the representative of the Territory, and if they are not entirely satisfactory the agreement can be terminated.

3. Accounts for payment of salaries, travel, and subsistence, supplies, or other expenses necessary to the completion of the work shall 

be rendered in the manner required by the laws and regulations of 

the contracting parties, and vouchers shall be preferred to either 

party for payment according as it may be convenient or according 

to the balance remaining in the respective allotments.

4. The cost of publication is borne entirely by the Geological 

Survey.

The Territory of Hawaii was represented in the cooperation by the 

board of conservation appointed by Gov. Walter F. Frear, and consisted of J. P. Cooke (chairman), J. W. Caldwell, and E. V. Wilcox, 

until June 30,1913. After this date the Territory was represented by 

the board of commissioners of agriculture and forestry, consisting of 

W. M. Giffard (president and executive officer), A. Waterhouse, J. M. 

Dowsett, H. M. von Holt, and A. H. Rice.

SCOPE OF WORK.

The investigations of stream flow in the Territory are not complete, 

nor do they include all the streams that might advantageously be 

studied. They include, however, as many of the streams and ditches 

on the four larger islands as the available appropriations would allow. 

It is essential that records of stream flow should be kept during a period 

of years long enough to determine within reasonable limits the range 

of flow from the maximum to the minimum. The length of such a 

period manifestly varies for different streams. Experience has shown 

that the records should be kept from 20 to 30 years.

In the performance of this work an effort is made to reach the 

highest degree of precision possible with a rational expenditure of 

time and money. In all engineering work there is a point beyond 

which refinement is needless and wasteful, and this statement applies 

with especial force to stream-measurement work in Hawaii. It has 

been found, however, that it is possible to obtain data which are 

sufficiently accurate, although many of those presented in this report 

are for periods too short to admit of definite conclusions.

FIELD METHODS OF MEASURING STREAM FLOW.

BASE DATA.

In making plans for power, irrigation, municipal water supply, and 

other projects involving the use of water from surface streams it is 

necessary to have data from which both the total flow of the stream 

and its distribution from day to day throughout the year can be 

obtained. The data necessary for obtaining such information are
10 WATER KES0TJBCES OF HAW AH, 1913.

daily gage heights, which give the fluctuations of rise and fall of the 

stream, and measurements of discharge at various stages, from which 

a rating curve and table can be prepared, giving the discharge for 

any stage. Such a rating is possible from the fact that so long as the 

conditions at the controlling point in the stream remain the same 

there will be approximately the same discharge for any given gage 

height.

The determination of a discharge is termed a discharge measurement, and points at which discharge measurements are made and 

records of daily fluctuations of stage are kept for determining the 

daily flow are termed gaging stations.

Gaging stations may be divided into two classes, known as weir 

stations and velocity-area stations. At weir stations the head of 

water on the crest of the wen* is measured and the discharge computed by means of a formula. The discharge at velocity-area 

stations is obtained by measuring the velocity of the current and 

the area of the cross-section, the product of the two giving the discharge.

The data presented in this paper were collected at both weir and 

velocity-area stations.

WEIR MEASUREMENTS.

Unquestionably a wen* properly constructed and of a type for 

which accurate coefficients have been determined is one of the most 

convenient and reliable means of measuring small quantities of water. 

In practice, however, weirs rarely conform to the requirements 

imposed by the experimenter who derived the coefficients. If the 

crest of the wen* is sharp and clean and sufficiently high above the 

bottom of the leading channel and the end contractions are complete 

and the velocity of approach is wanting, or negligibly small, andif 

the head on crest is measured at a distance back of the overfall of at 

least the weir crest length, the Francis formula will give good results. 

On the other hand, if these essential conditions are not complied with, 

especially if the velocity of approach is considerable and the contractions are imperfect, the Francis formula will not give accurate results. 

This is particularly true if the weir is improperly constructed and there 

is leakage around and under it, as is so frequently the case in practice.

Observations made on various types of weirs in Hawaii show that 

of the weirs in use in the Territory not all are giving accurate results. 

If the error is known so that corrections can be made the trouble is 

largely mitigated, but faulty weir records are too often accepted without investigation as to their accuracy.
FIELD METHODS OF MEASUBING STKBAM FLOW. 11 

VELOCITY-AREA METHOD.

The velocity-area method of measurement consists of determining 

the mean or average velocity of the water past a given cross-section 

area. The area of the cross section at right angles to the direction 

of flow is determined by soundings which are taken at such distances 

apart as will develop the contour of the stream bed. The depths are 

recorded and also then* distances from some arbitrarily chosen initial 

point on one side of the stream.

The method of making the soundings depends on the size and stage 

of the stream. On ditches and small streams, where the depths and 

velocities are not large, a graduated rod may be used to advantage; 

on large streams, which must be measured from bridges or cables, a 

lead weight and sounding line must be used. The weights are of 

different sizes 6^, 10, or 15 pounds according to the swiftness of 

the current, and are torpedo shaped, so as to offer as little resistance 

as possible to the moving water.

On streams with beds which are permanent or nearly so a standard 

cross section is usually constructed from careful soundings and 

referred to the zero of the gage, so that the depths for any stage can 

be found by adding the gage height at that stage to the depths below 

the zero of the gage. This method is especially useful at high stages, 

when it is difficult to make accurate soundings.

After the cross-section area of the stream has been measured by 

soundings and horizontal distances, the velocity is determined at a 

number of points. These measurements of velocity should be made 

at frequent intervals across the stream and close enough to take 

account of any abrupt change in the velocity. For convenience, the 

velocities are usually observed in the same verticals at which soundings are made. On some streams fairly good measurements of velocities may be made by means of subsurface floats. This method is 

applicable, however, only to channels of uniform cross-section area 

over a considerable distance and is very unsatisfactory for use on 

natural streams like those of Hawaii.1

The velocity of flow is best determined by the current meter, which 

is a form of water wheel actuated by the current, and of such size and 

shape that it can easily be placed at any point in the stream.

The new type of penta-recording current meter consists of six cups 

attached to ja vertical shaft which revolves on a conical hardenedsteel point isrhen immersed in moving water. The revolutions are 

indicated electrically or acoustically. The rating, or relation between 

the velocity of moving water and the revolutions of the wheel, is 

determined ;'or each meter by drawing it through still water for a

given distam at different speeds and noting the number of revolu-

12 WATER RESOURCES OF HAWAII, 1913.

tions for each run. From these data a rating table is prepared which 

gives the velocity in. feet per second of moving water for any number 

of revolutions in a given time interval. The ratio of revolutions per 

second to velocity of flow in feet per second is very nearly a constant 

for all speeds and is approximately 0.45.

Three classes of methods of measuring velocity with current meters 

are in. general use multiple-point, single-point, and integration.

The two principal multiple-point methods in general use are the 

vertical velocity curve and 0.2 and 0.8 depth.

In the vertical velocity-curve method a series of velocity determinations are made hi each vertical at regular intervals, usually about 

10 to 20 per cent of the depth apart. By plotting these velocities as 

abscissas and then* depths as ordinates and drawing a smooth curve 

among the resulting points, the vertical velocity curve is developed. 

This curve shows graphically the magnitude and changes in velocity 

from the surface to the bottom of the stream. The mean velocity 

in the vertical is then obtained by dividing the area bounded by this 

velocity curve and its axis by the depth. This method of obtaining 

the mean velocity in the vertical is probably the best known, but 

on account of the length of time required to make a complete measurement its use is largely limited to the determination of coefficients 

for purposes of comparison.

In the second multiple-point method the meter is held successively 

at 0.2 and 0.8 depth, and the mean of the velocities at these two 

points is taken as the mean velocity for that vertical. On the assumption that the vertical velocity curve is a common parabola with horizontal axis, the mean of velocities at 0.22 and 0.79 depth will give 

(closely) the mean velocity in the vertical. Actual observations 

under a wide range of conditions show that this multiple-point 

method gives the mean velocity very closely for open-water conditions and that in a completed measurement it seldom varies as much 

as 1 per cent from the value given by the vertical velocity-curve 

method. It is very extensively used in the regular practice of the 

United States Geological Survey.

The single-point method consists in holding the meter either at 

the depth of the thread of mean velocity or at an arbitrary depth 

for which the coefficient for reducing to mean velocity has been 

determined or must be assumed.

Extensive experiments by means of vertical velocity curves show 

that the thread of mean velocity generally occurs between 0.5 and 

0.7 total depth. In general practice the thread of mean velocity is 

considered to be at 0.6 depth, and at this point the meter is held in 

most of the measurements made by the single-point method. A 

large number of vertical velocity curve measurements, taken on 

many streams and under varying conditions, show that the average 

coefficient for reducing the velocity obtained at 0.6 depth to mean
FIELD METHODS OF MEASURING STREAM FLOW. 13

velocity is practically unity. The variation of the coefficient from 

unity in individual cases is, however, greater than in the 0.2 and 0.8 

method and the general results are not as satisfactory.

In the other principal single-point method the meter is held near 

the surface, usually 1 foot below, or low enough to be out of the effect 

of the wind of other disturbing influences. This is known as the subsurface method. The coefficient for reducing the velocity taken at 

the subsurface to the mean has been found to be in general from 

about 0.85 to 0.95, depending on the stage, velocity, and channel 

conditions. > The higher the stage the larger the coefficient. This 

method is especially adapted for flood measurements, or for measurements when the velocity is so great that the meter can not be kept 

in the correct position for the other methods.

The vertical integration method consists in moving the meter at a 

slow but uniform speed from the surface to the bottom and'back again 

to the surface and noting the number of revolutions and the time 

taken in the operation. This method has the advantage that the 

velocity at each point of the vertical is measured twice. It is useful 

as a check on the point methods. In using the Price meter great 

care should be taken that the vertical movement of the meter is not 

rapid enough to vitiate the accuracy of the resulting velocity determination.

In practical work on rough streams, such as exist in Hawaii, the 

meter should be held at 0.6 depth for depths of 1 foot or less. For 

greater depths the meter should be held at two points in the vertical, 

0.2 and 0.8 from the surface.

When the mean velocities in the different verticals have been 

found, the average of two adjacent means is taken as the mean 

velocity for that individual section. The area of the section is 

computed by multiplying the width of the section by the mean depth. 

The discharge of each section is then the product of the area multiplied 

by the mean velocity, and the total discharge of the stream results 

from summing up the discharge of the individual sections. In practice the work is tabulated in such a way as to render the computation 

very simple.!1

Current meter measurements are not practicable where there are 

eddies, cross currents, swirls, or passages for the water underneath 

stones. It is usually possible, however, to improve the channel by 

removing bowlders and rocks, so that a satisfactory measuring section may bd obtained, even on rough, steep streams such as exist in 

Hawaii.

Three kinids of velocity-area gaging stations are in general use in 

Hawaii, according to the means provided for making the observations 

of depth and velocity. They are wading, bridge, and cable stations.

* For a discussioji of methods of computing the discharge of a stream see Engineering News, June 25, 

1908.
14 WATEE EESOTTECES- OF HAWAII, 1913.

A wading station is one at which measurements are made only 

by wading; that is, no means exist for getting above the water at 

any stage except by wading. Such stations are usually on ditches 

or wide, shallow streams, which do not fluctuate greatly in flow. 

Frequently, however, measurements are made at low stages by wading, even though other means exist for making measurements at 

higher stages.

A bridge station is one at which the meter is used from a bridge. 

In some places highway or other bridges are available from which 

to make measurements, but generally they are not at the right place 

on the stream. Special bridges are then built.

A cable station is one at which measurements are made from a 

cable spanning the stream. Cable stations are used on large streams, 

such as Hanapepe, Wailua, and Hanalei rivers on the island of Kauai, 

and Wailuku River on the island of Hawaii. The cable supports the 

car from which a man works above the water. Distances are marked 

off on the cable itself or on a small auxiliary cable stretched taut 

above it.

A suitable place for a gaging station having been selected, a staff 

gage is set in the edge of the stream, either vertical or inclined, but 

graduated into tenths, half-tenths, or hundredths of feet vertically. 

The gage is securely fastened to rocks or trees to prevent displacement by floods and is so placed that the zero, or reference datum, is 

well below extreme low water. The datum is also referred to a permanent bench mark as an additional precaution. A water-stage 

recorder is then installed or an observer is engaged to record the 

heights of water morning and evening, and the mean of the two 

readings is used as the mean gage height for the day. Owing to the 

rapid rise and fall of most of the streams in Hawaii, two gage-height 

readings a day will not as a rule give a true mean for the 24 hours. 

For this reason, and also owing to the fact that many of the gaging 

stations are necessarily situated in the mountains at points remote 

from all habitations and difficult of access, it has generally been 

found necessary to use water-stage recorders. These instruments are 

of various types, some requiring weekly visits and others operating 

for a month without attention.

The essential features of water-stage recorders comprise a float 

free to rise and fall with fluctuations of the water surface, a device for 

transferring the motion of the float to the record sheet (either directly 

or through a reducing mechanism), the recording device, and the clock. 

The instruments may be designed for any range of stage. Those 

used by the United States Geological Survey in Hawaii are designed 

for ranges up to as high as 36 feet, but so far those having a 20-foot 

range have been found to be sufficient for any stage.

DEFINITION OF TERMS.

The volume of water flowing in a stream the "run-off" or "discharge" is Expressed in various terms, each of which has become 

associated more or less definitely with a certain class of work. These 

terms may be divided into two groups: (1) Those which represent a 

rate of flow, as "second-feet"; "gallons per minute," "gallons per 24 

hours/' "miner's inches," and "run-off in seeond-feet per square 

mile," and (2) those which represent the actual quantity of water, as 

"run-off in depth in inches," "million gallons," and "acre-feet." 

They may be defined as follows:

"Second-foot" is an abbreviation for cubic foot per second, and is 

the unit for the rate of discharge of water flowing in a stream 1 square 

foot in cross section at a rate of 1 foot per second. It is generally 

adopted as the fundamental unit in the measurement of flowing water 

and is the "natural" unit, as the foot and the second are the units 

used in making the physical determinations. Other units may be 

computed frd>m this by the use of factors given in the table of equivalents.

"Gallons per minute" is generally used in connection with punfping 

and city water supply, the United States gallon of 231 cubic inches 

being the unit of quantity and 1 minute the unit of time.

The "miner's inch" is the unit for the rate of discharge of water 

that passes through an orifice 1 inch square under a head which varies 

locally. It is commonly used by miners and irrigators throughout the 

West, and is defined by statutes in each State in which it is used.

"Second-feet per square mile" is the average number of cubic feet 

of water flowing per second from each square mile of area drained, on 

the assumption that the run-off is distributed uniformly both as regards time and area.

"Run-off in niches" is the depth to which the drainage area would 

be covered if all the water flowing from it in a given period were conserved and uniformly distributed on the surface. It is used for comparing run-off with rainfall, which is usually expressed in depth in 

inches.

An "acre-foot" is equivalent to 43,560cubic feet, and is the quantity 

required to cover an acre to the depth of 1 foot. The term is commonly used in connection with storage for irrigation.

In the Territory of Hawaii a unit commonly used in connection with 

the measurement of water is the "million gallons." This is used with 

two meanings (1) to indicate a rate of flow and (2) to express an 

actual quantity of water. In the former sense "million gallons per 24 

hours" is inferred, 1,000,000 gallons being taken as the unit of quantity and 24 tours as the unit of time. With this meaning the term is 

generally usjsd in connection with pumping and irrigation. In the
16 WATER RESOURCES OF HAWAII, 1913.

latter sense "million gallons" as an absolute quantity is used in the 

measurement of storage capacities .of reservoirs.

The following convenient approximate relations exist between 

second-feet, million gallons per 24 hours, and acre-feet: 1 secondfoot flowing 24 hours equals about 2 acre-feet; 1,000,000 gallons 

equals about 3 acre-feet; and 1 second-foot equals approximately 

two-thirds million gallons per 24 hours.

"Man's water" is an irrigator's terms also in common use in Hawaii. 

It signifies the amount of water that one irrigator can properly handle 

in the field. It varies greatly, being dependent upon the condition of 

the furrows, the age of the crop, and the skill and individuality of the 

irrigator.

OFFICE METHODS OF COMPUTING AND STUDYING 

DISCHARGE AND RUN-OFF.

At the end of each year the field or base data for current-meter 

gaging stations, consisting of water-stage record sheets, daily gage 

heights, discharge measurements, and notes from observers' books 

are assembled. The measurements are plotted on cross-section paper 

and rating curves are drawn wherever feasible. The rating tables 

prepared from these curves are then applied to the tables of daily 

gage heights to obtain the daily discharge, and from these applications the tables of monthly discharge and run-off are computed.

Rating curves are drawn and studied with special reference to the 

class of charfnels which they represent. The discharge measurements for all classes of stations, when plotted with gage heights in 

feet as ordinates and discharges in second-feet as abscissas, define 

rating curves which are generally more or less parabolic in form. 

For many stations curves of area in square feet and mean velocity 

in feet per second are also constructed to the same scale of ordinates 

as the discharge curve. These are used mainly to extend the discharge curves beyond the limits of the plotted discharge measurements, to check the form of the discharge curve, and to determine 

and eliminate erroneous measurements.

For every rating table the following assumptions are made for the 

period of application of the table: (a) That the discharge is a function of and increases gradually with the stage; (6) that the discharge 

is the same whenever the stream is at a given stage, and hence such 

changes in conditions of flow as may have occurred during the period 

of application are either compensating or negligible, except that the 

rating, as stated in the footnote of each table, is not applicable for 

periods during which the channel was obstructed; (c) that the 

increased and decreased discharge due to change of slope on rising 

and falling stages is either negligible or compensating.

18 WATER RESOURCES OF HAWAII, 1913.

As already stated, the gaging stations may be divided into several 

classes, as indicated in the following paragraphs:

The stations of class 1 represent the most favorable conditions for 

an accurate rating and are also the most economical to maintain. 

The bed of the stream is usually composed of rock and is not subject 

to the deposit of sediment and loose material. This class includes 

also many stations located in a pool below which is a permanent 

rocky riffle that controls the flow like a weir. Provided the control 

is sufficiently high and close to the gage to prevent cut and fill at the 

gaging point from materially affecting the slope of the water surface, 

the gage height will for all practical purposes be a true index of the 

discharge. Discharge measurements made -at such stations usually 

plot within 2 or 3 per cent of the mean discharge curve, and the 

rating developed from that curve represents a very high degree of 

accuracy.

Class 2 comprises mainly stations on rough, mountainous streams 

with steep slopes. The beds of such streams are, as a rule, comparatively permanent during low and medium stages, and when the 

flow is sufficiently well defined by an adequate number of discharge 

measurements before and after each flood the stations of this class 

give nearly as good results as those of class 1. As it is seldom possible to make measurements covering the time of change at flood 

stage, the assumption is often made that the curves before and after 

the flood converged to a common point at the highest gage height 

recorded during the flood. Hence the only uncertain "period occurs 

during the period of actual change in conditions of flow.

Class 3 includes those stations where the stream bed is of a shifting 

character, or the controlling section below the gage frequently 

changes owing to cutting out by the current and the filling in of sand, 

gravel, and drift. In some cases in Hawaii changes are caused by 

the growth of vegetation in the stream bed. No absolute rule 

can be laid down for stations of this class. Each rating curve must 

be constructed mainly on the basis of the measurements of the current year, the engineer being guided largely by the history of the 

station and the following general law: If all measurements ever made 

at a station of this class are plotted on cross-section paper, they will 

define a mean curve which may be called a standard curve. It has 

been found in practice that if after a change caused by high stage a 

relatively constant condition of flow occurs at medium and low 

stages, all measurements made after the change will plot on a smooth 

curve which is practically parallel to the standard curve with respect 

to ordinates or gage heights. This law of the parallelism of rating 

curves is the fundamental basis of all ratings and estimates at stations 

with semipermanent and shifting channels. It is not absolutely correct, but, with few exceptions, answers all the practical requirements
OFFICE METHODS. 19

of estimates made at low and medium stages after a change at a high 

stage. This law appears to hold equally true whether the change 

occurs at the measuring section or at some controlling point below. 

The change is, of course, fundamentally due to change in the channel caused by cut or fill, or both, at or near the measuring section. 

For all except small streams the changes in section usually occur at 

the bottom. The following simple but typical examples illustrate 

this law:

(a) If 0.5 foot of planking were to be nailed on the bottom of a wellrated wooden flume of rectangular section, there would result, other 

conditions of flow being equal, new curves of discharge, area, and 

velocity, each plotting 0.5 foot above the original curves when 

referred to the original gage. In other words, this condition would 

be analogous to a uniform fill or cut in a river channel which either 

reduces or increases all three values of discharge, area, and velocity 

for any gage height. In practice, however, such ideal conditions 

rarely exist.

(&) In the case of a cut or fill at the measuring section, there is a 

marked tendency toward decrease or increase, respectively, of the 

velocity. In other words, the velocity has a compensating effect, and 

if the compensation is exact at all stages the discharge at a given 

stage will be the same under both the new and the old conditions.

(c) In the case of uniform change along the crest of a weir or 

rocky control, the area curve will remain the same as before the 

change, and it can be shown that here again the change in velocity 

curve is such that it will produce a new discharge curve essentially 

parallel to the original discharge curve with respect to their ordinates.

Of course, in actual practice such simple changes of section do not 

occur. The changes are complicated and lack uniformity, a cut at 

one place being largely offset by a fill at another, and vice versa. 

If these changes are very radical and involve large percentages of 

the total area as, for example, on small streams there may result 

a wide departure from the law of parallelism of rating curves. In 

complicated changes of section the corresponding changes in velocity 

which tend to produce a new parallel discharge curve may interfere 

with each other materially, causing eddies, boils, backwater, and 

radical changes in slope. In such extreme conditions, however, the 

measuring section would more properly fall under class 4 and would 

require very frequent measurements of discharge. Special stress is 

laid on the fact that in the lack of other data to the contrary the 

utilization of this law will yield the most probable, results.

Slight changes at low or medium stages of an oscillating character 

are usually averaged by a mean curve drawn among them parallel 

to the standard curve, and if the individual measurements do not
20 WATER RESOURCES OF HAWAII, 1913.

vary more than 5 per cent from the rating curve the results are 

considered good for stations of this class.

Class 4 comprises stations on streams that have soft, muddy, or 

sandy beds. Good results can be obtained from such sections only 

by frequent discharge measurements, the frequency ranging from a 

measurement every two or three weeks to a measurement every day, 

according to the rate of diurnal change in conditions of flow. These 

measurements are plotted and a mean or standard curve drawn 

among them. It is assumed that there is a different rating curve 

for every day of the year and that this rating is parallel to the standard curve with respect to their ordinates. On the day of a measurement the rating curve for that day passes through that measurement. 

For days between successive measurements it is assumed that the 

rate of change is uniform, and hence the ratings for the intervening 

days are equally spaced between the ratings passing through the two 

measurements. This method must be modified *or abandoned 

altogether under special conditions. Personal judgment and a 

knowledge of the conditions involved can alone dictate the course 

to pursue in such cases.

The computations have, as a rule, been carried to three significant 

figures. Computation machines and the 20-inch slide rule have 

been generally used. All computations are carefully checked.

After the computations have been completed they are entered in 

tables and carefully studied and intercompared to eliminate or 

account for all gross errors so far as possible. Missing periods are 

filled in, so far as feasible, by means of comparison with records for 

adjacent streams. The attempt is made to complete years or periods 

of discharge, thus eliminating fragmentary and disjointed records. 

Full notes accompanying such estimates follow the daily and monthly 

discharge tables.

EXPLANATION OF TABLES.

For each regular current-meter gaging station are given in general 

the following data: Description of station, list of discharge measurements, table of daily discharge, table of monthly and yearly discharge, 

and run-off in acre-feet.

All rates of flow are expressed as second-feet, because distances and 

depths are measured in feet, and velocities in feet per second. The 

flow is thus obtained in cubic feet per second, or more briefly in 

"second-feet." The term "million gallons per 24 hours" is not used 

except in a few tables where data have been furnished in these units 

by private cooperations. "Million gallons per 24 hours" is not a 

primary but a derived unit. To convert second-feet into million 

gallons per 24 hours multiply by 0.646.
ACCUEACY OP FIELD DATA. 21

In addition to statements regarding the location and installation 

of curren't-meter stations, the descriptions give information in regard 

to any conditions which may affect the constancy of the relation of 

gage height to discharge, covering such points as shifting channels 

and backwater; also information regarding diversions which decrease 

the total flow at the measuring section. Statements are also made 

regarding the accuracy and reliability of the data.

The discharge-measurement table gives the results of the discharge 

measurements made during the year, including the date, name of 

hydrographer, gage height, and discharge in second-feet.

The discharge measurements and gage heights are the base data 

from which rating tables, daily discharge tables, and monthly discharge tables are computed.

The table of daily discharge gives the discharge in second-feet corresponding to the observed gage height as determined from the rating 

table, the number of significant figures used varying with the size 

of the discharge.

In the table of monthly discharge the column headed "Maximum" 

gives the mean flow, as determined from the rating table, for the day 

when the mean gage height was highest. As the gage height is the 

mean for the day, it does not indicate correctly the stage when the 

water surface was at crest height and the corresponding discharge 

was consequently larger than given nj the maximum column. Likewise in the column of "Minimum" the quantity given is the mean 

flow for the day when the mean gage height was lowest. The column 

headed ' 'Mean" gives the average flow in cubic feet for each second 

during the month. The "run-off in acre-feet" given in the column 

under that head is computed from the mean discharge in second-feet.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS.

The accuracy of stream-flow data depends (1) on permanence of 

the relation between discharge and stage, and (2) on the accuracy 

of observations of stage, measurements of discharge, and interpretation of data.

The accuracy column in the monthly discharge table does not 

apply to the maximum or minimum nor to any individual day, but 

to the monthly mean. It is based on the accuracy of the rating, the 

probable reliability of the observer, the number of gage readings per 

day, the range of the fluctuation in stage, and knowledge of local 

conditions. In this column, A indicates that the mean monthly 

flow is probably accurate within 5 per cent; B, within 10 per cent; 

C, within 15 per cent; D, within 25 per cent. Special conditions are 

covered by footnotes.

It should be borne in mind that the observations in each succeeding 

year may be expected to throw new light on data already collected 

and published.

WAINIHA RIVER (EAST AND WEST CHANNELS) AT POWER HOUSE, NEAR

WAINIHA, KAUAI.

Location. About 2 miles south of Wainiha and just northeast of Kauai Electric Co.'s

power house. 

Records available. East Channel, February 25, 1912, to December 31, 1913; West

Channel, December 30, 1911, to December 31, 1913. 

Drainage area. 14.7 square miles. 

Gage. Two inclined timber gages one on each channel to obtain the total flow of

the river at this point. 

Control. Two large channels, both rocky and probably permanent. The natives

build fish dams at the point where the river divides above the stations, and this

shifts the water from one channel to the other. 

Discharge measurements. Made from wire suspension footbridge over each

channel, or by wading.

Accuracy. East Channel, records fair; West Channel, records good. 

Cooperation. Stations maintained in cooperation with the Kauai Electric Co.

a New gage established May 15>, 1913. & New datum; gage moved to better location. 

ISLAND OF HAWAII. 

GENERAL CONDITIONS.

The perennial streams of the Island of Hawaii are mainly included 

in two groups, one comprising an area about 10 miles wide, in the 

Kohala and Hamakua districts, and the other an area about 16 miles 

wide in the Hilo district between the South Branch of Wailuku River 

on the southeast and Maulua Gulch on the northwest.

The low water run-off from the Kohala and Hamakua districts is 

now practically all diverted into ditches serving the sugar lands of 

the north coast of the island. Only a small part of the mean run-off 

from the Hilo district is now being utilized, the greater part being 

allowed to waste into the sea.

It has been proposed to construct a high-line canal at an elevation of 

about 2,700 feet and carry this water to serve either the semiarid lands 

of Kau on the south side of the island, or the dry government lands 

in the vicinity of Waimea which are now being leased for cattle range.

In September, 1911, a concession was sought, and later granted, 

by a promotor for the construction of what was generally known as 

the Kau ditch project, and at the request of the territorial officials 

the work of investigating the run-off of the Hilo district along the 

2,700-foot contour was begun. In September, October, and November, 1911, a foot trail was cut through the swamp and jungle from 

the South Branch of Wailuku River to the North Branch of Kawainui 

River, a distance of about 8 miles by trail. Staff gages were established on all appreciable channels, whether of perennial discharge or 

not.

Eighty-three stations were established an'd a camp was built about 

midway on the trail. Lack of funds prohibited further extension of 

the work and the construction of bridges or cables across the large 

gulches with the result that the larger streams could not be crossed 

when in flood. The trail was merely a passage cut through the
ISLAND OF HAWAII. 153

jungle, over and under logs, in and out of gulches, and, for the greater 

part, from a few inches to several feet deep in swamp muck. Two 

gage readers were employed who lived in the midway camp and who 

went over the trail once a day on an average of about four days in 

the week and read the gages one man working south and the other 

north and return. The condition of the trail was such that about 

eight hours were necessary to cover the 8-mile trip. All supplies for 

the camp and work were packed in on men's backs from the end of 

the Kaiwiki homestead road, a distance of about 3^ miles. One day 

of the week was allowed the observers for packing in supplies, and 

one day for rest. Up until May, 1913, when funds became available 

for the construction of cableways across the larger gulches, many 

daily records were lost on account of the observers being unable to 

cross these gulches when in flood. On account of the flashy type of 

the streams it was found that two readings daily, within a few hours 

of each other, gave a very poor index of the daily mean gage heights 

of the streams.

In the spring of 1913 it became apparent that the Kau ditch project would not soon be completed, and this fact, coupled with the high 

cost of obtaining the unsatisfactory and meager data on surface 

fluctuation, led to the suspension of the work until funds would be 

available to construct a dry trail across the entire district, to establish water-stage recorders on the larger streams, and to improve 

cross sections, controls, and other features. The work was suspended on July 18, 1913.

Ten rain gages read at monthly and bimonthly periods were established at approximately 500-foot elevation intervals from sea level 

to 5,000 feet, the approximate elevation at which the wet, or forest, 

zone meets the arid lava slopes of Mauna Kea Mountain. Practically all rainfall above the 5,000-foot contour is absorbed by the 

porous lava. Rainfall observations were terminated on June 30, 

1913.

HILO GROUP. 

STATIONS AT 2,700-FOOT LEVEL.

Location. On trail in forest back of Hilo, at approximately 2,700 feet above sea 

level. The trail is about 8 miles long and the camp, about midway on the trail, 

is reached by a foot trail 3£ miles long from the end of the Kaiwiki homestead 

road. The camp is about 7 miles west-northwest from Hilo. Beginning at the 

South Branch of Wailuku River, the stations are numbered from 1 to 18 and from 

25 to 87, including stations Nos. 12a and 86a, to the North Branch of Kawainui 

River. There are no stations numbered 19 to 24.

Records available. Stations 1-12, October 6, 1911, to July 18, 1913. Station 12a, 

November 30, 1912, to July 18, 1913. Stations 13-18, 25-27, October 5, 1911, to 

July 18, 1913. Stations 28-41, September 28, 1911, to July 18, 1913. Stations 

42-47, September 28, 1911, to July 18, 1913. Stations 48-50, September 31, 1911, 

to July 18, 1913. Stations 51-52, October 7, 1911, to July 18, 1913. Stations
154 WATER RESOURCES OF HAWAII, 1913.

53-65, October 10, 1911, to July 19, 1913. Stations 66-68, October 21, 1911, to 

July 18, 1913. Stations 69-74, November 13, 1911, to July 18, 1913. Stations 

75-86, November 14, 1911, to July 18,1913. Station 86a, November 18,1912, to 

July 18,1913. Station 87, November 14, 1911, to July 18, 1913.

Drainage area. About 75 square miles for all stations (may be in error 20 per cent).

Gages. Vertical staff read to nearest two-hundredths, twice daily, about 4 days in 

the week.

Diversions. All low-water run-off is diverted below the stations, but it is estimated 

that less than 20 per cent of the mean discharge is being utilized; no diversions 

above the stations.

Accuracy. At only 24 of the 83 stations maintained is the discharge sufficient to 

warrant current-meter measurements and ratings; mean discharge at each of the 

other 59 stations is one-half second-foot or less; the aggregate mean run-off of 

these 59 stations for the period January 1 to June 18, 1913, is estimated to have 

been only 4.2 second-feet. As the mean discharge of the 24 streams rated was 

194.0 second-feet, the mean run-off for the 59 estimated stations was less than 2 

per cent of the total. For these stations for which ratings have been made and 

results published rating curves are all fairly well defined for low and medium 

stages. Discharge for days for which there are no gage-height records was estimated from daily rainfall records at camp near station No. 51.

The total mean run-off for all stations for the period January 1 to July 18, 1913, waa 

198.2 second-feet. The minimum run-off, which was less than 6 second-feet, occurred 

in March. The maximum run-oft of all stations probably exceeded 5,000 second-feet.

Discharge measurements made at unrated stations on 2,700-foot level near Hilo, Hawaii, 

during the period Jan. 1 to July 18, 1913.

KOHALA GROUP. 

KOHAT.A DITCH NEAR KOHALA, HAWAII.

Location of weirs. The Kohala Ditch Co. (Ltd.) maintains three weirs which 

measure the discharge carried by the Kohala ditch. The Awini weir is on the 

southeast side of the east branch of Honokanenui Gulch at an elevation of 1,880 

feet. The Mulii weir is about 3J miles south of Niulii, Kohala district, at an 

elevation of 1,000 feet, and about 5 miles below the Awini weir. The Hawi weir 

is about 1J miles south of the Hawi mill near the lower end of the ditch.

Records available. Daily records at Awini and Niulii weirs kept by Kohala Ditch 

Co. July 1,1907, to December 31,1913. No record of flow at Hawi weir, which has 

been used mainly as a check on deliveries of water between Niulii and Hawi. 

The Niulii weir measures the amount of water shown by the Awini weir and also 

the inflow from the Honokanenui. The record for the Honokenenui is derived by 

subtracting the flow at the Awini weir from the flow at the Niulii weir.

Gages. Vertical staffs graduated to hundredths.

Discharge measurements. Each weir consists of three 5-foot panels with end 

contractiens, sharp-beveled steel crest, and with very slight velocity of approach.

Diversion. Ditch diverts and delivers to the plantations on the north coast of Hawaii 

all low-water run-off between the Honokane Gulch and the northwest point of 

the island below the 2,000-foot contour.

Cooperation. Daily-discharge record furnished by Kohala Ditch Co. (Ltd.).

BAIN GAGING.

The rainfall of the Hawaiian Islands is extremely variable, ranging 

from a few inches at several low-level, leeward localities to more than 

600 inches per annum, usually at elevations above 2,000 feet and on 

the windward sides of the islands. Valleys lying on the same sides 

of the islands and within a few miles of each other may have a variation in mean annual precipitation of several hundred per cent. The 

rainfall may also vary greatly m the same valley for different elevations. As a rule the zones of heaviest precipitation are on the 

windward sides of the islands, 2,000 to 3,000 feet above sea level.

Generally the daily rain gages maintained by the United States 

Weather Bureau are located at low levels. Lack of funds and the 

absence of inhabitants at high-level localities have prevented the 

maintenance of Weather Bureau stations at high levels, although in 

a number of cases daily records are furnished that bureau by occupants and caretakers of mountain houses and ranches. The data 

furnished by the Weather Bureau are therefore generally of little 

value hi their relation to stream run-off.
RAIN GAGING. 175

When high levels have been accessible and funds available highlevel rain gages, which are read monthly and bimonthly, have been 

established by this office and some valuable records obtained. To 

determine the precipitation of the Territory accurately would require 

the installation of thousands of gages and the construction of hundreds of miles of trails.

Acknowledgment for cooperation in furnishing rainfall data is due 

the following: Kauai Kekaha Sugar Co., Makee Sugar Co., Hawaiian 

Sugar Co., Grove Farm Plantation, W. F. Sanborn of Princeville 

Ranch, Kauai Electric Co., and J. McClellan Oahu, C. C. Bitting,

The tables on pages 180-185 show the precipitation at stations maintained by the Geological Survey and precipitation data furnished from 

private sources which are not included in United States Weather 

Bureau records, to which those interested in further data are referred.
