Time-of-travel of Solute Data for Mississippi Streams 

By J. Kerry Arthur 

ABSTRACT

This report summarizes the time-oftravel of solutes information for 

Mississippi streams that is available in 

the files of the U.S. Geological Survey. 

The time-of-travel information was 

tabulated for 926 miles of stream reaches in 

seven of the ten major drainage basins in the 

State. The data were collected during 

studies conducted from 1963 through 1980. 

Estimation of time-of-travel of solutes is 

important for environmental studies of 

streams and may be critical in the event 

of accidental or other spills of 

contaminants into a waterway. 

INTRODUCTION 

The U.S. Geological Survey (USGS) 

collaborated with the Mississippi 

Department of Environmental Quality, 

Office of Pollution Control (MDEQ-OPC), 

in a project to compile all the time-of-travel 

of solute information on Mississippi streams 

located in the files of the USGS. The 

purpose of the report is to present all the 

available time-of-travel information for 

Mississippi streams in a single document in 

order to facilitate the use of the data. 

The possibility of accidental or 

intentional (bio-terrorism) spills of 

contaminants into Mississippi steams is of 

concern to those using water from the rivers 

in the State. Estimating solute travel time in 

streams is important in the event of spills of 

contaminants and for pollution studies. A 

tabulation of all the time-of-travel 

information for Mississippi streams in one 

publication will be beneficial to the public

and to local, State, and Federal agencies. 

The time-of-travel information in 

Mississippi was collected from 1963 

through 1980 along 926 miles of stream 

reaches in seven of the ten major drainage 

basins in the State (fig. 1). The time-oftravel information presented in this report 

was collected by the USGS. Exceptions are 

the information on Red Creek and part of the 

data collected on Tallahalla Creek. The U.S. 

Public Health Service collected the 

information presented for these two streams. 

Although time-of-travel data were 

collected as part of various USGS studies 

having a wide range of objectives, scopes, 

and cooperators, all these studies used 

similar procedures to determine solute timeof-travel. The time-of-travel data were 

determined by injecting known amounts of 

fluorescent dye into streams at selected sites 

and measuring the travel time of the dye to 

downstream sampling points. Rhodamine B 

or Rhodamine WT fluorescent dye was used 

as the tracer in all the studies. The dye 

concentrations in the water samples 

collected were measured in the field by

using a fluorometer. The final analysis to 

determine relative dye concentration of each 

water sample was made under uniform

temperature conditions. The travel time of 

the dye was determined by using the time of 

collection of the water sample containing the 

peak concentration of dye. In some of the 

studies, the time-of-travel of the leading and 

trailing edges of the dye cloud was 

determined. The leading edge of the dye

plume is the first detection of a dye 

concentration greater than background 

fluorescence. The trailing edge is the time 

when the dye concentration decreased to 

about 10 percent of the peak concentration. 

Most of the studies were made during 

1
periods with little or no surface runoff or 

during periods when the streams were at or 

near base flow conditions. Stream discharge 

measurements using Price current meters 

were made during most of the studies, and 

where measurements were not available, 

stream discharge was estimated. 

PRESENTATION OF DATA 

Time-of-travel of solute information 

was compiled from the individual project 

files at the USGS. In instances where the 

information was in field form, the data were 

reduced, checked, and tabulated. Time-oftravel information was tabulated for the 

following drainage basins and stream groups 

in Mississippi (fig. 1). 

• Tombigbee River Basin (fig. 2) 

• Pascagoula River Basin (fig. 3) 

• Coastal streams Basin (fig. 4) 

• Pearl River Basin (fig. 5) 

• Yazoo River Basin (fig. 6)

• Big Black River Basin (fig. 7) 

• Independent streams Basin (fig. 8) 

The stream reaches in each basin with timeof-travel of solute information are shown in 

figures 2-8. The drainage basin names are 

consistent with the names used by the 

MDEQ-OPC.

The time-of-travel of solute information 

for Mississippi streams is presented in 

table 1. The data tabulated for each stream

consist of the following parameters: 

• Date of study--Month and year of 

study. 

• Reach--Location of beginning and 

end of reach. 

• County--Name of county of reach. 

• Latitude--Degrees, minutes, and 

seconds of latitude at beginning and 

end of reach. 

• Longitude--Degrees, minutes, and 

seconds of longitude at beginning

and end of reach. 

• Length of reach--Length of reach 

in miles. 

• Solute time-of-travel, in hours--

Elapsed travel time of dye cloud 

from the beginning to the end of the 

reach. 

• Lead edge--Leading edge of 

dye cloud. 

• Peak--Peak concentration in 

dye cloud. 

• Trail edge--Trailing edge off 

dye cloud. 

• Solute rate of travel, in miles per 

hour—Rate of travel time of dye 

cloud from the beginning to the end 

of the reach. 

• Lead edge--Leading edge of 

dye cloud. 

• Peak--Peak concentration in 

dye cloud. 

• Stream discharge, in cubic feet 

per second 

The Pascagoula River Basin (fig. 3) has 

the greatest total miles (336 miles) of river 

reaches with time-of-travel of solute 

information. The basin with the next 

greatest miles (280 miles) of river reaches 

with time-of-travel information is the Pearl 

River Basin (fig. 5). Of the remaining 

basins with time-of-travel data, the Yazoo 

River Basin (fig. 6) has the least miles (32.0 

miles) of time-of-travel information. 

The Pearl River has the greatest miles 

(222 miles) of river reaches with time-oftravel of solute information. The 

Chickasawhay River in the Pascagoula 

Basin has the next greatest miles (84.5 

miles) of river reaches with time-of-travel 

information. The Big Black River has the 

2
third greatest miles (73.0 miles) of river 

reaches with data. All the river reach 

mileage (51.3 miles) with time-of-travel 

information on the independent streams is 

on the Homochitto River. Within the Yazoo 

River Basin, the Tillatoba Creek Basin has 

all the stream reach mileage (32.0 miles)

with time-of-travel information. For the 

coastal streams, Wolf River has most of the 

stream reach mileage (51.7 miles) with timeof-travel information. Most of the river 

reach mileage (43.0 miles) with time-oftravel information in the Tombigbee River 

Basin is on the Tombigbee River. The 

remainder of the time-of-travel information 

on stream reaches in the Tombigbee Basin 

(27.4 miles) is on Town Creek near Tupelo. 

Several of the streams have time-oftravel of solute information at more than one 

flow rate for an individual stream reach. 

Stream reaches of the Tallahala Creek Basin 

have time-of-travel information for four 

stream discharges. The streams in the 

Tillatoba Creek Basin within the larger 

Yazoo River Basin have time-of-travel 

information for three stream discharges. 

The Pearl River, the Leaf River, and Red 

Creek have stream reaches with time-oftravel information at two stream discharges.
