Magnitude and Frequency of Floods in Alabama, 2015

By Brandon T. Anderson

Abstract 

To improve flood-frequency estimates at rural streams 

in Alabama, annual exceedance probability flows at gaged

locations and regional regression equations used to estimate 

annual exceedance probability flows at ungaged locations

were developed by using current geospatial data, new

analytical methods, and annual peak-flow data through

September 2015 at 242 streamgages in Alabama and 

surrounding States. The regional regression equations were

derived from statistical analyses of annual peak-flow data

and basin characteristics for a subset of 217 streamgages. 

Four flood regions were identified based on residuals from

the regional regression analyses and contain sites with similar

basin characteristics. A separate set of equations was derived

for estimating flood frequency and magnitude for small rural 

streams using a subset of 40 small basin streamgages. A large 

river analysis was also completed for 14 selected large-river

streamgages in Alabama. Annual exceedance probability 

flows presented in this report reflect additional streamflow

data collected since the previous study of flood magnitude and 

frequency in Alabama, which included streamflow through

September 2003. 

Introduction

Improved flood-frequency information is important 

for the effective management of flood plains, including the 

safe and economic design of bridges, culverts, dams, levees, 

and other structures near streams. The last flood-frequency 

study for Alabama was published more than 11 years ago

(Hedgecock and Feaster, 2007). Since that time, improvements 

in statistical techniques, specifically the Expected Moments 

Algorithm (EMA) and the multiple Grubbs-Beck (MGB) 

test for potentially influential low floods, have increased the

accuracy of flood-frequency estimates (Cohn and others, 

1997, 2013). The EMA allows for the incorporation of

censored observations, historic flood data, low outliers, and

uncertain data points in the flood-frequency analysis, while

the MGB test increases the accuracy of peak-flow statistics by

objectively and systematically detecting and removing low,

highly variable peak flows and is recommended for use with

the EMA. 

In 2016, the U.S. Geological Survey (USGS), in 

cooperation with the Alabama Department of Transportation,

began a study to update the regional flood-frequency equations 

(regional regression equations [RREs]) and annual exceedance 

probability (AEP) flows for rural streams in Alabama by using

recent geospatial data, new analytical methods, and additional

annual peak-flow data through the 2015 water year.1 Results 

of flood frequency studies, including AEP flows and RRE

information, are published and also incorporated into the 

USGS StreamStats application, an online tool that provides 

flood-response planners and water managers in Alabama

with basin characteristics and estimates of flow statistics at

locations on both gaged and ungaged streams (http://water.

usgs.gov/osw/streamstats/; USGS, 2017a). 

Purpose and Scope

The purpose of this report is to describe the methods and 

results of a study to (1) update flood regions for all areas in 

Alabama; (2) update the AEP flows for rural streams at gaged

locations; (3) update RREs for use at rural ungaged locations 

in Alabama; and (4) update the AEP flows for streamgages

on large, regulated streams. All data used in support of the 

analysis and presented in this report, including geographic 

information system (GIS) data for the four flood regions in 

Alabama, are available from Anderson (2020). Urban stream 

flood frequency equations were not updated as part of this

study and the results from Hedgecock and Lee (2010) are 

provided in table 1 for convenience. This report updates the 

flood-frequency analysis published by Hedgecock and Feaster 

(2007).

Description of the Study Area

The study area (fig. 1) includes the State of Alabama 

and selected locations in Georgia, Mississippi, Tennessee, 

and Florida. Rainfall in Alabama generally is associated with

the movement of warm and cold fronts across the State from

November through April and isolated thunderstorms from May 

through October. From June to September, tropical storms or 

1

The water year is the annual period from October 1 through September 30

and is designated by the year in which the period ends. For example, the 2013

water year is from October 1, 2012, through September 30, 2013.

hurricanes occasionally enter the State along the Gulf Coast 

and produce unusually large amounts of rainfall. The average 

annual precipitation for Alabama is 53.05 inches (U.S. Climate 

Data, 2018). The average annual high and low temperatures

are 76.5 and 53.5 degrees Fahrenheit, respectively (U.S. 

Climate Data, 2018).

Previous Investigations

 Magnitude and frequency of floods in Alabama have 

been described by Pierce (1954), Speer and Gamble (1964), 

Gamble (1965), Barnes and Golden (1966), Hains (1973), 

Olin (1984), Atkins (1996), and Hedgecock and Feaster 

(2007). Magnitude and frequency of floods for rural streams 

with small drainage areas have been described by Olin and

Bingham (1977) and Hedgecock (2004), and for urban 

streams by Olin and Bingham (1982) and Hedgecock and 

Lee (2010). 

Data Compilation

USGS streamgages in Alabama, Georgia, Mississippi, 

Florida, and Tennessee that had 15 or more years of annual 

peak-flow data were used in this analysis. A 50-mile (mi)

buffer was used from the Alabama State boundary for rural

streams, and a 90-mi buffer was used for small rural streams.

The gages used in this study were either continuous-record

or crest-stage gages. Continuous-record gages are equipped 

with instrumentation to record the height of the water surface

above the gage datum, or stage, of the water body at fixed

time intervals. The stage data are transmitted by satellite to 

USGS offices and are applied to a stage-streamflow rating

to determine flow for the given stage value. Crest-stage

gages record only the peak stage of a flood; the peak stage 

is then applied to a stage-streamflow rating to determine

the associated flow. Hereinafter, these two types of gages

collectively are referred to as streamgages. A rainfall event of 

high magnitude occurred in the latter part of December 2015

for many gaged locations in Alabama. This was the peak of

the 2016 water year and was included in the analysis for those

locations. 

Peak-Flow Data and Basin Characteristics

The RRE analysis was conducted using data from

217 streamgages (152 in Alabama and 65 from adjacent 

States) that had 15 or more years of annual peak-flow data

collected through the end of the 2015 water year (Anderson, 

2020). Annual peak-flow data for the streamgages were

downloaded from the USGS National Water Information

System (NWIS) database (U.S. Geological Survey, 2017b). 

The drainage areas of the 217 streamgages range from 0.13 to 

1,766 square miles (mi2). In addition, there were 14 large river

streamgages, included in a separate analysis, whose drainage

areas range from 1,675 to 30,810 mi2. 

Basin characteristics for each streamgage included in 

this study were obtained by using the USGS map-based web

application StreamStats (U.S. Geological Survey, 2017a). The 

following basin characteristics were tested for significance in

the generalized least-squares (GLS) regression analysis:

• Contributing drainage area (A), in square miles, 

upstream from the streamgage;

• Main channel slope (S), in feet per mile, between

points 10 and 85 percent of the distance from the 

streamgage to the basin divide;

• Main channel length (L), in miles, between the

streamgage and the basin divide;

• Lag-time factor (T), defined by the ratio L/S 0.5 with L

and S defined above;

• Forest cover (F), in percent, percentage of the total 

contributing drainage area covered by forests;

• Storage (St), in percent, percentage of the total 

contributing drainage area covered by lakes, ponds, 

and swamps; and

• Width-to-length ratio (W/L), the average basin width

to basin length. The average basin width (W) is the 

drainage area (A) divided by the main channel length 

(L). This ratio is essentially a basin shape factor.

Large river streamgage

and number

Regional regression 

streamgage and 

number.

Streamgage numbers correspond 

to table 1 in Anderson (2020)

Figure 1. Locations of streamgages used in regional regression analysis and selected large-river streamgages in Alabama.

Magnitude and Frequency of Floods in Alabama, 20

Percentage of developed (urban) land and average 

percentage of impervious area taken from the 2011 National 

Land Cover Database and available in StreamStats, were

computed for each basin because soil types (Hedgecock and 

Feaster, 2007) and land use can influence runoff. Initial GLS 

regression analyses were performed for all the streamgages

included in the study, incorporating multiple combinations of 

the above-mentioned explanatory variables. These regressions 

were used in the development of statewide equations for

estimating AEPs. Statewide regression equations that included

drainage area as the only explanatory variable had standard 

errors of prediction that were within 1 percent of the standard

errors, produced from equations that included main channel 

slope, forest cover, and storage. Therefore, equations that 

included drainage area as the only explanatory variable were

used for regionalization purposes. 

Flood-Frequency Analysis

Annual peak flood flow data for the streamgages in

this study were analyzed to produce AEP flows for each

streamgage. Results are available from Anderson (2020) 

and can be found in Appendix 1. A regional analysis was

conducted based on the residuals of the streamgages in order 

to group basins with similar hydrologic characteristics. As a

result, four flood regions were determined from the regional

analysis, and regional flood frequency equations for ungaged 

streams were developed from the annual peak flow data at

streamgages that fell within these regions. Separate studies

were also conducted to derive equations for small stream

basins and update the previously published large river basins 

analysis.

Analysis of Flow at Streamgages

For each streamgage, a log-Pearson type III (LP3) 

mathematical probability distribution was fit to annual peak

flow data and then used to estimate streamflow values for

the range of recurrence-intervals at each streamgage as 

described in Bulletin 17C (England and others, 2019). The 

LP3 distribution is a three-parameter distribution that requires 

estimates of the mean, standard deviation, and skew coefficient

of the population of base 10 logarithms of annual peak flows

at each streamgage (Parrett and others, 2011). The EMA 

method improves upon the standard LP3 method by allowing

for the analysis of historic peak datasets containing censored 

observations, historic data, low outliers, and uncertain data

points and accommodates the interval data by using perception 

thresholds and flow intervals (Cohn and others, 1997). In the

EMA analysis the perception thresholds are used to describe 

the flood knowledge in each year within the flood record

and represents the observable range in floods (England and 

others, 2019). If no historic, censored, or interval data are 

incorporated, the EMA method produces estimates of the 

three LP3 statistics that are identical to those produced by the 

standard LP3 method described in Bulletin 17B (Interagency 

Advisory Committee on Water Data, 1982). Bulletin 17C did

not publish regional skew values therefore general-skew and

corresponding mean square error (MSE) values from Bulletin 

17B were used to weight the AEP flow values.

The basic equation for fitting the LP3 distribution to a 

measured series of annual peak flows is

logQp= Χ +KpS, (1)

where

Qp is the P-percent AEP flow, in cubic feet per

second;

Χ is the mean of the logarithms of the annual 

peak flows;

Kp 	 is a factor based on the skew coefficient and

the given percentage of annual exceedance 

probability, which can be obtained from

appendix 3 of Bulletin 17B (Interagency 

Advisory Committee on Water Data,

1982); and

S is the standard deviation of the logarithms of 

the annual peak flows.

In previous USGS reports about floods in Alabama, the 

term “recurrence interval, in years” was used to characterize

flood frequency (50-year flood and so forth). The USGS and 

other Federal agencies now refer to the P-percent chance 

of occurrence as an AEP. For example, the 0.02 AEP (Q2%) 

has a 2-percent chance of occurring in any given year and 

corresponds to a recurrence interval of 50 years (reciprocal of 

the AEP, table 2) (Griffis and Stedinger, 2007). An increase 

in the number of years of annual peak-flow record at a

streamgage increases the level of confidence in AEP flow

estimates. For example, 30 years of annual peak-flow record

likely will have a lower variance than 10 years of record, thus

increasing the confidence of the estimated AEP flows.

Table 2. T-year recurrence intervals with corresponding annual

Flood-Frequency Analysis

The MGB test, a generalization of the Grubbs-Beck 

method, provides a standard procedure for identifying lowflow outliers and multiple potentially influential low floods

(PILFs) (Cohn and others, 2013). PILFs are annual peaks 

that meet three criteria: (1) their magnitude is much smaller 

than the flood quantile of interest; (2) they occur below a

statistically significant break in the flood-frequency plot; 

and (3) they can have excessive influence on the estimated 

frequency of large floods. The USGS PeakFQ software,

version 7.1, available at https://water.usgs.gov/software/

PeakFQ/ (U.S. Geological Survey, 2014), was used to

conduct the flood-frequency analyses following the EMA

methodology, including the MGB test. The estimates of the 

AEP flows at gaged sites were computed by using the EMA

and MGB to test for PILFs. These PILFs were excluded from

the AEP flow computations at the streamgage. The final AEP

flows at streamgages should be determined by weighting the

station skew coefficient with the generalized skew coefficient

from Bulletin 17B (Interagency Advisory Committee on Water 

Data, 1982).

Regional Regression Analysis

Initially, 242 streamgages were considered for inclusion

in the regional regression analysis. Streamgage information 

and additional data related to the regional regression analysis 

are provided in Anderson (2020). Annual peak-flow records

of the streamgages were evaluated for backwater, regulation,

diversion, channelization, and urbanization by inspecting 

NWIS peak-flow data qualification codes, and sites having

any of these attributes were removed. Annual peak-flow

data for the sites are available from the NWIS database 

(U.S. Geological Survey, 2017b) and can also be found in 

Appendix 2. Streamgages in basins that have more than 

10 percent impervious area were also removed, leaving

217 streamgages suitable for use in the regional regression 

analysis (fig. 1). 

To determine the flood regions, a statewide ordinary

least squares (OLS) regression equation was developed by

using drainage area as the only explanatory variable for the 

1-percent AEP (Q1%). The residuals for each streamgage, 

which represent the difference between observed values and

the predicted values of streamflow, were evaluated to detect

any geographic biases or clusters. Four flood regions were

delineated in Alabama (fig. 2), based upon review of residual

plots, previous reports, eight-digit hydrologic unit code maps, 

geologic maps, and physiographic maps. The four flood 

regions in this report differ slightly from the previous report 

by Hedgecock and Feaster (2007). These differences include 

a streamgage originally located in region 1 (USGS station 

no. 02445245, plate 1; Hedgecock and Feaster, 2007) that is 

now located in region 2. One streamgage originally located in

region 4 (USGS station no. 02419000, plate 1; Hedgecock and 

Feaster, 2007) is now located in region 3.

AEP estimates obtained from flood-frequency analysis of 

the 217 streamgages were related to basin characteristics by

using OLS multiple linear regression analysis to evaluate the 

statistical significance of each basin characteristic (Wagner 

and others, 2016). The USGS weighted-multiple-linear

regression program (WREG) version 1.05 (https://water.

usgs.gov/software/WREG/) was then used to complete the

final GLS regression analysis (Eng and others, 2009; U.S. 

Geological Survey, 2013). In GLS regression, streamgages 

are weighted according to differences in streamflow record

length, the variance of streamflow measurements in the record,

and spatial cross correlations of concurrent flows among

streamgages. 

Regression diagnostics were reviewed to identify

streamgages that have high leverage and (or) high influence 

metrics. The leverage metric was used to compare the values

of independent variables at one streamgage to the values of the 

same variables at all other streamgages. The influence metric 

was used to determine if a streamgage had a high influence

on the estimated regression values (Eng and others, 2009). A 

streamgage may have a high leverage metric, indicating that 

its independent variables are significantly different from those 

at all other streamgages, but the same streamgage may not 

have a high influence on the regression metrics. A streamgage 

with a high influence may not have a high leverage metric.

Sometimes high leverage or influence metrics are indicative 

of incorrect values for a given independent variable. These 

data were reviewed resulting in one site being removed from

the dataset, leaving a total of 217 streamgages used in the 

analysis. Standard errors of prediction of the generalized 

least-squares models ranged from 9 to 58 percent. Pseudo 

coefficients of determination of the models ranged from 75 to 

100 percent.

Application and Limits of Methods

When applying the RREs, users are advised not to 

interpret the empirical results as exact. Regression equations 

are statistical models that must be interpreted and applied 

within the limits of the data and with the understanding that

the results are best-fit estimates with an associated variance.

Methods for estimating AEP flows in Alabama differ between

gaged locations, ungaged locations on gaged streams, and 

locations on ungaged streams.

Flood-Frequency Analysis

Small Stream Analysis

Data from 40 streamgages were used to conduct a

separate GLS regression analysis on the rural small streams 

in Alabama with drainage areas ranging from 0.13 to

14 mi2. The distance outside of the Alabama State line for 

streamgage consideration was increased from 50 mi used in

the streamgage selection for the regional equations to 90 mi. 

This change in distance was needed to increase the number of

streamgages in the analysis (fig. 3). If a rural ungaged small 

stream is within 0.13 to 14 mi2, AEPs could be computed 

with either regional or small stream equations (tables 3 and 4,

respectively). It is recommended that if the drainage area at 

the ungaged location is within the range of 0.13 to 5 mi2, then 

the small stream equations should be used because the AEP 

accuracy is improved. 

Large River Analysis

Flood-frequency analysis for streamgages along the 

main stems of the Alabama, Coosa, Conecuh, Tallapoosa, 

Tennessee, Tombigbee, and Black Warrior Rivers were not

included in the regional flood-frequency analysis because 

the drainage areas of these rivers are substantially larger 

than those of the streamgages used in the regional analyses 

and, in some cases, encompass more than one flood region. 

In addition, most of these large rivers are subject to varying 

degrees of regulation. Where the data analysis indicated it 

was appropriate, analysis of flood magnitudes to drainage

area were determined for selected AEPs. The flood-frequency

analyses are summarized in the following sections for each

river listed and AEP flows are available from Anderson (2020)

and in Appendix 1. The estimated AEP flows were based

on LP3 analysis of peak-flow data at the gaged sites on the

streams, as described in Bulletin 17C (England and others, 

2019). Graphical inspection of the data from each analysis 

indicated that an LP3 distribution yielded a reasonable fit of 

the frequency curves for the selected streamgages. Because 

most of these large rivers have some degree of regulation, 

trend analyses were performed on the annual peak flows

for the selected streamgages to determine if regulated flow

patterns have changed with time. Trends in regulation were

assessed by using the Mann-Kendall test and cumulative 

plots of daily mean flows (single mass curves, Helsel and

Hirsch, 1995). The single mass curve is a basic analytical tool 

showing a plot of cumulative values against time. The slope

of the mass curve represents the constant of proportionality 

between the two quantities (Searcy and Hardison, 1960). A

change in the slope of the curve indicates a change in the 

proportionality constant. In the case of regulated streams, the 

single mass curve can be used to assess whether patterns of

regulation have remained relatively consistent over time. For 

the large rivers, a flood-frequency analysis was performed

if the annual peak-flow record at a streamgage showed no

trend in either the entire dataset or a part of the dataset. AEP 

estimates at multiple gages on a stream will vary as a result

of several factors, including length of the annual peak-flow

records, concurrent periods of record, intervening tributaries, 

and areal coverage of storm systems causing the floods. For 

example, if a storm system affected only the lower half of

a large drainage basin, streamgages in the upper half of the 

basin would not record runoff from the storm. The flood of

record at a streamgage in the lower half of the basin may not

necessarily be the flood of record at a streamgage in the upper 

half of the basin. As a result of these factors, interpolation of 

AEP estimates between two streamgages on the same stream

may not be linear. However, linear interpolation between two

streamgages with relatively similar lengths of record should

provide a reasonable estimate of flood magnitude for locations 

between the two streamgages.

Alabama River 

Flow in the Alabama River is regulated by upstream

reservoirs on both the Coosa and Tallapoosa Rivers. For 

the Alabama River near Montgomery (USGS station 

no. 02420000, plate 1), two different datasets were analyzed

(1886–2015 and 1928–2015) that represent different periods 

of record with varying degrees of regulation. The 1928–2015

dataset represents the period of regulation and was used for

this analysis. 

No new data were available for the following

streamgages on the Alabama River: Alabama River at Selma 

(USGS station no. 02423000), Alabama River near Millers 

Ferry (USGS station no. 02427500), and Alabama River at 

Claiborne (USGS station no. 02429500). Because no new

analyses were conducted, the values found in the previous

report (Hedgecock and Feaster, 2007) should be used.

Coosa River

Flow in the Coosa River is regulated by reservoirs at

Carters Pond, Allatoona, Weiss, H. Neely Henry, Logan 

Martin, Lay, Mitchell, and Jordan Dams. For the Coosa

River at Gadsden (USGS station no. 02400500, plate 1), 

no additional data had been collected since the last floodfrequency report (Hedgecock and Feaster, 2007); therefore, no 

new analysis was done.

For the Coosa River at Childersburg, Ala. (USGS station 

no. 02407000, plate 1), a trend analysis of the entire period 

of record (1916–2016) indicated a change in high-flow

patterns in the early to mid-1960s. This trend coincides with

the construction of Weiss, H. Neely Henry, and Logan Martin 

Reservoirs (1961, 1966, and 1964, respectively). No trends 

were detected for the period prior to 1961, indicating that from

1916 to 1960, flow patterns were relatively consistent. Flow

at Childersburg was only regulated by the dam at Allatoona

prior to 1961, and the effects of regulation were considered

minimal. An LP3 analysis was conducted on the 1967–2016

period of record, which is considered indicative of current,

post-regulation flood-frequency conditions. A comparison 

of flood-frequency estimates for the pre-regulation period 

(1916–60) by Hedgecock and Feaster (2007) with those for

the post-regulation period (1967–2016) indicates that the 

estimates of the magnitudes of larger floods (lower AEP) are

not substantially different. 

For the Coosa River at Jordan Dam near Wetumpka,

Ala. (USGS station no. 02411000, plate 1), two periods were

considered for analysis (1913–1984 and 1985–2013). The 

period 1985–2013 was considered to better represent current

regulated conditions. 

Tallapoosa River

Annual peak flows in the Tallapoosa River is regulated

by reservoirs at R. L. Harris, Martin, Yates, and Thurlow

Dams. For the Tallapoosa River at Wadley, Ala. (USGS station

no. 02414500, plate 1), a trend analysis of the entire period of 

record (1924–2016), which included a mixture of unregulated

and regulated flows, indicated no significant change in highflow patterns. Using the entire period of record was considered

acceptable because there was no trend apparent in the dataset,

and the graphical fit of an LP3 distribution was reasonable.

For the Tallapoosa River below Tallassee, Ala. (USGS

station no. 02418500, plate 1), flood-frequency analyses were

run on four different periods of record: (1) 1920–2013, which

includes annual peaks from the various regulation periods and 

the 1920 historic peak from the unregulated period; (2) 1929–

2013, which excludes the 1920 historic peak; (3) 1929–1983,

which is the period prior to completion of the R.L. Harris

Dam; and (4) 1984–2013, which is the period after completion

of the R.L. Harris Dam. Results of the Mann-Kendall test

indicated no statistically significant trend in any of the four 

periods. The LP3 curve fit the data reasonably well for all

four periods. Given the similarities in the frequency curves, 

the uncertainty of how storage from Martin and R.L. Harris

Dams would have affected the 1920 historic peak, and the fact

that the frequency curve fits the data reasonably well, it seems

appropriate to publish flood-frequency estimates computed by 

using the data from the period 1929–2013 (app. 1).

Tennessee River

A flood-frequency analysis was performed for the

Tennessee River at Whitesburg, Ala. (USGS station no. 

03575500, plate 1). For comparison, four LP3 analyses 

were made: (1) the complete period of record (1925–2011),

(2) 1944–2011, (3) 1944–2011 with a historical period of

1867–1943, and (4) 1968–2011, which is the period after all

major upstream dams were in place. The period of record

selected for flood-frequency analysis was 1944–2011, during

which all the dams on the Tennessee River were in place. The

results of the Mann-Kendall test and the results of singlemass curves plotted for this streamgage indicate that the 
Flood-Frequency Analysis

high-flow patterns have been relatively consistent since 1944.

Inspection of the flow record for the streamgage upstream

of Whitesburg, the Tennessee River at Chattanooga, Tenn. 

(USGS station no. 03568000, plate 1), indicates that floods 

in 1867, 1875, 1886, and 1917 were the four largest that

occurred at this location between 1867 and 2003. These flood

events occurred primarily before regulation of the Tennessee 

River and before the streamgage at Whitesburg became active 

(1925). One of these flood peaks could have been the largest at 

the Whitesburg streamgage, but would not be reflected in this

flood-frequency analysis. 

For the Tennessee River at Florence, Ala. (USGS station 

no. 03589500, plate 1), three LP3 analyses were made: (1) the

complete period of record from 1895 to 2013, including the 

1867 historic peak and associated historical period 1867–

1894; (2) 1944–2013; and (3) 1944–2013 with a historical

period 1867–1943. The period of record from 1944 to 2013, 

with a historical period 1867–1943, was used for the final

flood-frequency analysis. This dataset represents a period 

during which all dams on the Tennessee River were in place.

The results of the Mann-Kendall test and the single-mass 

curves plotted for this streamgage indicate that high-flow

patterns have been relatively consistent since 1944. 

Tombigbee River

Annual peak flows in the Tombigbee River are

regulated by locks and dams at Bevill, Heflin, Demopolis,

and Coffeeville, and by numerous locks and dams on the 

Tennessee-Tombigbee Waterway in Mississippi. For the

Tombigbee River at Gainesville, Ala. (USGS station no. 

02449000, plate 1), no data were collected at this streamgage

since the previous report (Hedgecock and Feaster, 2007); 

therefore, no update was performed.

For the Tombigbee River near Coatopa, Ala. (USGS 

station no. 02467000, plate 1), a trend analysis for the entire 

period of record (1893–2015) indicated a change in highflow patterns in the early to mid-1970s. This trend most

likely coincided with the beginning of construction of the

Tennessee-Tombigbee Waterway in 1973. Trend analyses of

the period prior to 1974 indicate that relatively consistent 

flow patterns were present. Therefore, an LP3 analysis was

performed on the period of record 1974–2015, which was

considered indicative of regulated flood-frequency conditions. 

Annual peak flows resulting from floods occurring after 1973

may be somewhat attenuated by the effects of the TennesseeTombigbee Waterway.

For the Tombigbee River near Coffeeville, Ala. (USGS 

station no. 02469761, plate 1), the period of record available 

is 1961–2015. Two LP3 analyses were made, one of the

complete periods of record (1961–2015) and another of the 

period 1974–2015. Floods occurring after 1973 may be of 

somewhat lesser magnitude because of the effects of the

Tennessee-Tombigbee Waterway, although the 1979 peak

was the peak of record and was flagged as being the highest

since 1874. Therefore, the period of record 1974–2015 was

used and is considered indicative of regulated flood-frequency 

conditions. 

Black Warrior River

For the Black Warrior River at Northport, Ala. (USGS 

station no. 02465000, plate 1), the complete period of record 

(1929–2015) was used for the LP3 analysis. Two reservoirs

are located upstream from the streamgage at Northport. The 

Mann-Kendall test and single-mass curves for the period 

1929–2015 indicated consistent peak-flow patterns.

For the Black Warrior River near Eutaw, Ala. (USGS

station no. 02466030, plate 1), the complete period of record 

from 1977 to 2012 was used for the LP3 analysis. The MannKendall test indicated no trend for this period, and the LP3 

distribution fits the dataset reasonably well. This period of

record is indicative of current, regulated flood-frequency 

conditions. Other streamgages on the Black Warrior River 

were not analyzed because they either did not have enough

record with a consistent flow pattern or the record was

maximum daily average flow.

Conecuh River

For the Conecuh River near Brooklyn, Ala. (USGS 

station no. 02374000, plate 1), the systematic period of record 

is 1936–1957 with historic peaks in 1929 and 1975; the 1929

annual peak is considered to have been the highest flow since

1865. The historical period of record used for this analysis was

1865–1975. 

For the Conecuh River at State Highway 41 near

Brewton, Ala. (USGS station no. 02374250, plate 1), the

systematic period of record is 1999–2016 with historic peaks

in 1929 and 1975; the 1929 annual peak is considered to have 

been the highest flow since 1865. The historical period of

record used for this analysis was 1865–2016. A comparison of

the LP3 analysis for USGS station no. 02374250 with that for

USGS station no. 02374000 showed that the flood-frequency

estimates are not substantially different, which was expected

because there is only a 7-percent difference in the sizes of 

the drainage areas. For the 10- to 0.2-percent AEP floods, the 

results from USGS station no. 02374000 are within the same

confidence limits as those from USGS station no. 02374250.

Flood-Frequency Estimates at 

Streamgages in Alabama

The estimates of the AEP flows at streamgages were

computed by using the EMA and MGB to test for PILFs. AEP 

flows at streamgages should be determined by weighting the

station skew coefficient with the generalized skew coefficient

from Bulletin 17B (Interagency Advisory Committee on Water 

Data, 1982). The accuracy of AEP flows at streamgages can

be further improved by weighting those flows with RREpredicted AEP flows. The variance of prediction is a function

of the regression equations and the independent variables used 

to develop the flow estimate. If the estimated AEP flows at

streamgages and RRE-predicted AEP flows are assumed to

be independent and are weighted in inverse proportion to the

associated variances, the variance of the weighted estimate will

be less than the variance of either of the independent estimates. 

Once the variances have been computed, the two independent

flow estimates can be weighted by using the following

equation:

where

QP(g)w 	 is the weighted-flow estimate for the selected

recurrence interval, in cubic feet per 

second;

Vp,P(g)r is the variance of prediction at the streamgage, 

derived from the applicable RRE AEP, in 

log units;

QP(g)s is the estimate of peak flow at the streamgage

from the EMA analysis for the selected 

AEP, in cubic feet per second;

Vp,P(g)s is the variance of prediction at the streamgage 

from the EMA analysis for the selected 

AEP, in log units; and

QP(g)r is the estimate of peak flow at the streamgage

from the RRE for the selected AEP, in cubic 

feet per second.

The estimates of streamflow at streamgages were weighted

with the regional estimates of streamflow to compute a final set

of AEP flows. The weighted-flow estimates for the streamgages

in Alabama are provided in the data release associated with this

report (Anderson, 2020).

Flood-Frequency Estimates at Ungaged 

Locations on Gaged Streams

The AEP flows for a streamgage can be transferred to

an ungaged location on the same stream by using the areaweighting method. Equation 3 can be used if the drainage area

at an ungaged location on the stream is within 50 percent of

the drainage area at the streamgage (drainage area ratio is 

more than 0.5 or less than 1.5) (Ries and Dillow, 2006). The

drainage area ratio estimate for an ungaged location can be 

calculated by using the following equation:

Q

A

A P u Q u

g

b

( ) P g w 

















 

    , (3)

where

QP(u) is the drainage area ratio estimate of flood 

flow for the selected P-percent AEP for 

the ungaged location, u, in cubic feet per 

second;

A(u) is the drainage area of the ungaged location, 

in square miles;

A(g) is the drainage area of the upstream or 

downstream streamgage, in square miles;

QP(g)w 	 is the weighted estimate of flood flow for the

selected P-percent AEP for the upstream or 

downstream streamgage, in cubic feet per

second; and

b is the exponent of drainage area from the 

appropriate RRE (tables 3 and 4).

This method, however, does not weight the area-weighted

flows with the RRE flows for the ungaged location. The AEP

flows from the streamgage can be transferred and weighted

with RRE flows for the ungaged location by using the

following equation:

Q

A

where

QP(u)w is the weighted-flow estimate at the ungaged

location, in cubic feet per second;

QP(u)r is the RRE flood estimate at the ungaged 

location for the selected AEP, in cubic feet 

per second;

Ag is the drainage area of the streamgage, in 

square miles; 

	 │ΔA│ is the absolute difference in drainage areas 

between the ungaged location and the

streamgage, in square miles; and

QP(u) 	 is the estimate of flood flow for the selected

P-percent AEP for the ungaged location, 

u, in cubic feet per second computed from 

equation 3.

If the drainage area at an ungaged location differs by 

more than 50 percent from that of the streamgage, the RRE 

estimates should be used. If an ungaged location is between

two streamgages on the same stream, the site with the closest

drainage area ratio and longest period of record should be used 

(Sauer, 1974). 
Accuracy and Limitations of Regional Regression Equations

Flood-Frequency Estimates at 

Locations on Ungaged Streams

For locations on ungaged streams, the flood region 

should be determined by using figure 2 or StreamStats (http://

water.usgs.gov/osw/streamstats/; USGS, 2017a). The RREs 

for the appropriate flood region and size of drainage area 

should then be used to compute flows for the desired range of

AEPs (table 3 or 4). The standard error of prediction (SEP) is 

a measure of the accuracy of AEP flow estimates for ungaged

basins in each region. 

Accuracy and Limitations of Regional 

Regression Equations

The RREs and small-stream equations only apply to rural 

streams that can be described by using the basin characteristics 

and having drainage areas within the range of streamgages

in each region that were used to develop the equations

(table 5). These methods should not be used for sites in stream 

basins that are substantially affected by regulation from 

impoundments, channelization, levees, or other man-made 

structures. The RREs and small-stream equations also should 

not be applied to locations on streams in urban areas where

more than 10 percent of the basin is covered by impervious 

area. The methods do not apply where flooding is influenced

by extreme ocean storm surge or tidal events. Reliability of 

the RREs and small-stream equations for a location in a flood

region that has basin characteristics outside the limits of the

The accuracy of a flood-frequency estimate traditionally 

has been expressed in two ways—as the mean standard error

of the model or as the mean SEP. The mean standard error 

of the model is a measure of how well the regression model

fits the input data and represents the standard deviation of the 

differences between streamgage data and the corresponding

prediction from the regression equation. The SEP is a measure 

of how well the regression model estimates flood magnitudes

for ungaged basins. The SEP is the square root of the mean 

square error of prediction (MSEp). The MSEp is the sum of 

two components—the MSE resulting from the model and the

sampling MSE resulting from estimating the model parameters 

from samples of the population.

Summary and Conclusions

Flood-frequency estimates for rural Alabama streams 

were last updated in 2007; since that time, estimation

techniques have improved, and additional streamflow data are

available to improve the accuracy of such estimates. Thus, 

the U.S. Geological Survey, in cooperation with the Alabama

Department of Transportation, performed flood-frequency

analyses to estimate annual exceedance probability (AEP) 

flows at streamgages, developed regional regression equations

(RREs) to estimate AEPs at ungaged locations in rural 

Alabama, and performed flood-frequency analyses for large 

river basins. Many basin characteristics were analyzed, but

drainage area was the only characteristic that was statistically

significant and was used as an explanatory variable in the

RREs. The boundaries of four flood regions in the State of 

Alabama that were defined in the 2007 study were confirmed

and adjusted through use of the RREs. 

Additionally, equations were developed for small streams

in Alabama having a drainage area of 14 square miles or 

less. These RREs are recommended in order to improve the 

accuracy of the AEP flow estimates for sites with drainage

areas less than 5 square miles. 

Extreme flow events have the potential for devastating

impacts to the economy, infrastructure, and the landscape. 

Keeping flood-frequency analyses and RREs updated can 

provide water-resource managers the information needed

during flood-response planning. By broadening the regional 

approach for the development of flood-frequency RREs across 

State lines, flood-frequency estimates have the potential 

to be more accurate than previously calculated estimates 

and applicable to a larger study area. Finally, providing 

the analysis results on a publicly accessible web interface,

StreamStats (https://water.usgs.gov/osw/streamstats/), allows

a user to select a site of interest and obtain the AEP flows for

that site at any time.

Appendix 2

The following tables contain gage height and discharge (flow) data for streamgages in

Alabama. The tables contain a brief description of the gage location, type of gage, gage datum 

(if known), drainage area in square miles, historical data, and explanatory remarks. Elevations

are referenced to the National Geodetic Vertical Datum of 1929 (NGVD 29). The tables of

peak stages and discharges show only the annual maximums. The qualification codes in the

tables correspond to the peak data codes as used in the U.S. Geological Survey National Water 

Information System (NWIS). 

The following qualification codes apply to the discharge data:

1 discharge is a maximum daily average; 

2 discharge is an estimate; 

4	 discharge is less than indicated value, which is the minimum recordable discharge at

this site; 

5	 discharge affected to unknown degree by regulation or diversion;

6	 discharge affected by regulation or diversion;

7 discharge is a historic peak; 

A	 year of occurrence is unknown or not exact;

B	 month or day of occurrence is unknown or not exact;

E only maximum peak available for this year. 

The following qualification codes apply to the gage height data:

1	 gage height affected by backwater;

2 gage height not the maximum for the year; 

3	 gage height at different datum or at different site and datum;

5 gage height is an estimate.
