R-TOT Version 6 model development was funded by the
Louisiana Applied and Educational Oil Spill Research And
Development Program (OSRADP). Previous funding was
provided by OSRADP and the State of Louisiana Department
of Environmental Quality (LDEQ). The model utilizes data
which were collected by personnel of the Office of Water
Resources of the LDEQ, by the U.S. Geological Survey in
cooperation with the Louisiana Department of
Transportation and Development, the U.S. Army Corps of
Engineers, and by staff members of the University of
Southwestern Louisiana Center for Louisiana Inland Water
Studies (USL-CLIWS). These previous studies provide a basis
for the program described in this report.

Overview
R-TOT, the River Time-of-Travel Model, is a model for prediction of time of travel of a
solute or entrained material. Technical details of the calculation method have been published
elsewhere. Version 6 of R-TOT was programmed in Microsoft Visual Basic, and is distributed as
a “stand-alone” application which must be installed using the Windows Installation Wizard. The
model provides a convenient user interface for input, provides a summary output screen, and
easy user access to the data analysis and graphical capabilities available within spreadsheets like
Excel. R-TOT may be applied to other streams the distributed version applies to the Lower
Mississippi River. See the R-TOT Programmer’s Manual (Waldon and Gandikota, 1999) for
information on applying the model to other streams.
This manual is intended to assist the user in application of the R-TOT 6 Time-of-Travel
computer program. This program projects
the time of arrival, at a downstream location, of the leading edge of a spill in the
River
the arrival time of the peak concentration
the time the trailing edge of the spilled material will pass this location
if the amount of material spilled is known, the program also predicts the peak
concentration at the downstream location.
Time-of-travel models are useful in a number of water quality management applications,
including:
providing timely warning to downstream water users so that water intakes may be
shut down to avoid risks of contamination
predicting duration of a spill for water users to minimize potential water
shortages, loss of fire protection, etc.
spill contingency planning, spill prevention control and countermeasure (SPCC)
plans
spill training simulation
investigation of spills of unknown origin.
The model was designed to present a friendly and uncomplicated user interface, and to
provide a straight-forward computational approach which is intended to minimize the
programming effort required for incorporation of new study data or application to a new stream.
The program has been designed and tested to run only under the MS Windows 95/98 operating
systems. The user runs the program by activating the “*.exe” file. Following installation in the
Windows 10 operating system, “R-TOT 6" will be found in the alphabetical list of programs in
the Start menu. More information will be found in the file named readme.txt in the RTOT 6
folder following installation. Sections of this manual assist the user in determining appropriate
input values. In many situations, user advice is provided by the program to warn the user of
unusual conditions or input errors.
R-TOT Program User’s Manual, June 1999 (revised) page 5
Installation
Suggested minimum hardware requirements are 16 megabytes of installed RAM, and 5
free megabytes of hard disk space available prior to installation. It is also strongly suggested that
the user take precautions against introduction of computer viruses during installation of this, or
any other programs, by virus scanning the distribution files. Note that zipped (compressed) files
may need to be scanned before and after unzipping. Prior to installation it may be necessary for
the user to exit all programs, log off any network connections, and disable virus scanning
detection programs. In order to perform the installation, the user must have write privilege in the
Windows system area.
Installation is simple. The user should create a subdirectory for the model (for example
C:\R-TOT6). Copy the distribution file(s) to this directory, and follow the instructions provided
in the file, readme.txt, which is provided with the distribution, or simply run the distributed
“Setup.exe'' program. During program setup a query window may say that a more recent version
of a file already exists and asks if you want to keep the newer version. I suggest keeping the
newer version rather than installing the older version extracted from the distribution setup file.
To remove (or uninstall) R-TOT, use the Windows uninstall procedure available in
Control Panel” under “Add/Remove Programs.” Consult the distribution readme.txt file for any
additional information on installing or uninstalling future versions.
User input and model execution
There are a number of ways to execute the R-TOT 6 program. Following installation
R-TOT 6 should appear on the user’s “Start/Programs” menu. Alternatively, the user may simply
view the R-TOT subdirectory using Windows 95/98 Explore, and double-click the desired
“*.exe” name. The screen appearance of the R-TOT program may vary to some degree between
computers depending on the operating system settings and monitor resolution. In Windows 10
you may start R-TOT 6 by left-clicking it in the Start menu program list.
As the program runs, carefully and completely read the online instructions, warnings, and
error messages. Warnings provide potentially valuable suggestions and information concerning
your input selections and values. After a warning, you will have the option to return to the input
screen, or ignore the warning and continue to the output screen. Errors that are detected result in
an error message box being displayed for each error. The user is returned to the input screen
following error message displays.
R-TOT Program User’s Manual, June 1999 (revised) page 6
Determination of user input parameters
In order to calculate time-of-travel, the user must enter a value for the starting rivermile,
ending rivermile, and discharge. Additionally, the amount of contaminant spilled, if known, can
be entered in order to estimate peak concentration at the ending rivermile. Spill date2and time
are optional If any of these parameters are keyed in out-of-range of the model, the user will be
prompted by warning, or error messages. Errors are “fatal” to the program's ability to run, and
the program will return to the parameter input dialog sheet.
RIVERMILE. In R-TOT, locations are determined by distance, termed rivermiles (RM) ,
downstream of a selected zero point. In R-TOT 6, rivermiles upstream of this zero location are
negative. By convention, Mississippi River rivermiles are measured upstream from
Head-of-Passes (near the Gulf of Mexico). Thus, rivermiles for locations above head-of-passes
(AHP) on the Mississippi River are entered as negative numbers in R-TOT 6. The user is
assisted in providing rivermile locations through the use of a dropdown edit feature which
displays locations of selected sites along the modeled reach. The user may, optionally, enter a
site description following the rivermile value by entering a comma and a space after the number,
and appending the site description. More extensive lists of locations of landmarks and of
pipeline crossings are provided in appendices to this manual.
DISCHARGE. Discharge (or flow) is a required input parameter. The model will accept a direct
discharge value only in cubic feet per second (CFS). Discharge is entered as a single value, and
that value is applied to the entire reach3. This is usually adequate for conditions on the Lower
Mississippi River. If a spill is routed past the Old River Control Structure (RM -314 AHP) the
user will need to determine the change in discharge and spill mass resulting from the Old River
diversion.
The most expedient method for estimating discharge is to use values monitored by a
governmental agency. Discharges and stages monitored by the New Orleans District of the
Corps of Engineers may be obtained by calling a recorded message at (504)862-2461, or by
accessing the New Orleans District Corps of Engineers "Daily Stage and Discharge Data" web
site at:
https://www.mvn.usace.army.mil/Missions/Engineering/Stage-and-Hydrologic-Data/DailyStage
Discharge/
3Note - R-TOT Version 5 allowed the user to specify a variable discharge. This feature was
seldom, if ever used, and was removed to streamline user input. User calculated effects of
discharge change would likely assume that increases in discharge do not contain additional spill
mass, and therefore dilute the material concentration. A reduction in discharge is assumed to
represent a diversion or distributary, and appropriate mass would be removed to account for this
reduction of flow.
2The year value list in the distributed version cannot accept dates beyond 2015. However, users
can manually enter other year values.
R-TOT Program User’s Manual, June 1999 (revised) page 7
Discharge and stage data collected by the Louisiana District of the USGS in Baton Rouge may
also be available.
Discharge may also be measured or estimated through direct measurement. Techniques
for discharge measurement are briefly discussed in an appendix of this report.
SIZE OF SPILL. If the total weight (pounds or kilograms) of the contaminant of interest has
been estimated, enter the estimate in the appropriate input text box. The peak concentration of
the contaminant at the downstream site will then be projected. If the peak concentration
projection is not required, the contaminant mass may be entered as zero (0.0).
The most straight-forward method for estimating contaminant weight is to use a
reported total spill weight. For example, if 50 pounds of solvent containing 10% benzene is
reported spilled, 5 pounds of benzene would be entered. The Windows calculator may be
activated to assist the user in more complex calculations. Calculated values may be copied from
the calculator and pasted into the appropriate input box.
R-TOT alternatively allows for input of spill volume in gallons or barrels. In this case
the specific gravity (weight relative to a similar volume of water) of the material must also be
entered. A dropdown edit box provides some typical specific gravity values to assist the user in
estimating this parameter. For rough calculations, if specific gravity is unknown use a value of
1.0. As with contaminant weight, the volume entered should be the total spill volume multiplied
by the fraction of contaminant in the spilled material.
If the peak concentration has been measured at one downstream site, a second mass
estimation technique is to simply utilize the program peak concentration projection. Projected
peak concentration is proportional to the amount spilled. If the amount spilled is unknown, the
user may simply enter a convenient mass, 100 pounds for example. The actual spill mass may
then be estimated by adjusting the input mass by the ratio of the observed to the projected peak
concentration. For example, if a peak of 50 micrograms per liter, ug/L, was observed, and the
program projects 20 ug/L for a 100 pound spill, the actual spill mass would be estimated to be
250 pounds (100*50/20).
Note that R-TOT assumes that the spill material is conservative. That is, no loss of
material (mass) is assumed in the model. Because many spill materials will experience some
loss through degradation or volatilization, observed peak concentrations may often be lower than
concentrations projected by R-TOT.
R-TOT Program User’s Manual, June 1999 (revised) page 8
Examples4
(1) On July 4, 1997, at 10:15 AM, a fictitious barge accident spilled 2000 pounds of EDC
into the Mississippi River at rivermile 229.2, the I-10 bridge in Baton Rouge. River discharge on
that date was 792,000 cfs. What is the predicted time of arrival and spill duration at New
Orleans, rivermile 104.7? What is the peak concentration?
The input and output screens are displayed in Figures 1 and 2. The user must perform the
following tasks to complete this example:
enter a descriptive title
select known date/time
enter date and time, date and time dropdowns will appear
enter discharge value in CFS
enter rivermiles and descriptions of locations
or select rivermiles from the location drop down boxes
select units of spill size
enter spill size value
press “OK (run TOT)” button
examine output screen
To return the input screen simply select “back” at the top of the output screen. To print
both the input and output screens on your Windows default printer, dropdown the “File” menu
and select “print.” R-TOT 6 only prints to the current default printer. If you wish to print to a
different printer, temporarily change the default printer setting.

(2) In early August, 2001, you are making plans for a dye tracer study on the Mississippi
River. The dye time-of-travel study is planned to begin on August 19, 2001, at 9:00 AM. It will
be performed using 200 gallons of 20% dye solution having a specific gravity of 1.19. The dye
will be injected at rivermile 381, Waterproof, Louisiana. River discharge at the injection point
on that date is expected to be 682,000 CFS. Calculate the time-of-travel and peak concentration
at the Old River Control Structure (ORCS), rivermile 314 AHP.
Execution of example 2 is similar to example 1. Rivermile locations and descriptions are
entered, CFS discharges are entered. When units of gallons are selected, the “Material specific
gravity” input group will appear. Because the dye solution is only 20%, enter 0.238 (20% of
1.19) as the specific gravity, and 200 gallons as the spill amount. Figures 3 and 4 are the input
and output sheets for example 2.
(3) This example is a continuation of example 2, and illustrates the complexity which can result
from diversion or discharge variation. This example may be skipped by users who are not
interested in routing spills which pass the ORCS. The injection point is above the ORCS
(rivermile 314 AHP), and we now wish to project arrival time and peak concentration at Baton
Rouge, downstream of the ORCS. Roughly 23% of the Mississippi River discharge is diverted at
this point to the Atchafalaya River. On this date assume the discharge of the Mississippi River
below the ORCS is 514,000 CFS. What is the time of arrival and duration at the Highway 190
Bridge in Baton Rouge, rivermile 233.9? What is the peak concentration?
Input for Example 3 is similar to Example 2. Because this is a continuation, enter the
leading edge arrival time from Example 2 as the “Spill or Injection Date and Time,” August 20,
2001, at 4:03. The completed input sheet is shown in Figure 5. The R-TOT 6 output shown in
Figure 6 must now be adjusted to take into account travel time above the ORCS. Leading edge
arrival does not need adjustment. Peak arrival time will be 3:32 hours:minutes (from Figure 5,
22:35 - 19.03 hours:minutes) later than shown in Figure 6, arriving at 11:23 on 8/21/2001.
Similarly, the trailing edge will arrive 11:05 hours:minutes (Duration from Figure 5) later than
the time shown in Figure 6, arriving at 1:40 on 8/22/2001. Duration will be increased by 11:05
hours:minutes from 10:22 to 21:27 hours:minutes. Peak concentration will decrease in inverse
proportion to duration, falling from 0.6681 to (11.07/21.43)*0.6681 = 0.323 ug/L, and must
further be reduced because of mass loss diverted down the Atchafalaya River (514/682)*0.323 =
0.243 ug/L (the user could alternatively avoid this latter correction by reducing the spill amount
by a factor of 514/682 to 150.7 gallons in the Figure 5 input).

Importing R-TOT 6 output to a spreadsheet
R-TOT 6 results may be easily transferred to a spreadsheet. R-TOT generates
an output file named “RTOTTime.csv,” a comma delimited data file which can be
opened by Excel. In Excel, select File/Open. Then set “Files of type” to “Text files.”
Select the file “RTOTTime.csv.” The file with appropriate column headings will open.
Time-concentration curve estimation
An auxiliary Excel spreadsheet titled “CTCurve.xls'' was included with R-TOT 6.
That spreadsheet is no longer being updated or supported. The CTCurve spreadsheet
estimated a full temporal tracer/spill concentration curve from user input specifying the
time and concentration at the peak and two other points.
Riverspill web page
Some further information may be found on the original riverspill web page. This
page is hosted by the University of Louisiana, and was last updated in 2000. A slightly
newer riverspill website. The last major update of that website was made in 2004. In the
future the site may be extended to provide additional information.
R-TOT Program User’s Manual, June 1999 (revised) page 17
Appendix 1: Discharge measurement
There have been numerous methods developed for discharge measurement and
estimation (Rantz, 1982; Turnipseed and Sauer, 2010). Discharge may be estimated utilizing
any of the following techniques:
1. A direct physical measurement of discharge by boat or from a bridge - This
determination of discharge requires specialized equipment and trained personnel. In
this method numerous velocity and depth measurements are performed and used to
calculate discharge.
2. Tapedown measurement - A tapedown is a measurement from the water
surface to a known mark on a fixed structure. As the measurement decreases water
surface elevation and therefore flow increases. A stage-discharge (or
tapedown-discharge) relationship must be known to allow estimation of discharge from
tapedown measurement.
3. Stage Gage - Stage is the elevation of the water surface relative to some
datum. Discharge is determined using a stage-discharge relationship. A wire weight
gage or similar device is typically installed at an appropriate fixed location.
4. Time-of-travel - If time-of-travel data are available for a spill the discharge may
be determined through trial and error using R-TOT.

Appendix 2: Glossary of selected terms
The following list of terms and definitions is provided to assist the user in spill
modeling, and specifically in the use of the R-TOT models. The definitions presented
here are specifically provided for these purposes, and therefore may not provide the
most general or alternative meanings.
ADE Advection dispersion equation, also called the heat equation. Typically in river spill
modeling the one-dimensional form of this equation is applied.
advection Transport of water or material in water through the bulk water movement.
ADZ Aggregated dead zone model, an alternative to the ADE model. This model assumes that
a dead zone of constant volume or zones cause the delay and dispersion observed in spill
and tracer studies.
barrel A unit of volume measurement, for petroleum a barrel is 42 gallons.
buoyancy The tendency of a material to float. Positively buoyant materials tend to float,
negatively buoyant materials tend to sink.
CFS Cubic feet per second, a conventional unit of measure of volumetric discharge of a stream.
CLIWS Center for Louisiana Inland Water Studies, a research center under the Department of
Civil Engineering, University of Southwestern Louisiana
(http://www.ucs.usl.edu/~mgw0237/cliws.html).
cms Cubic meters per second, a metric unit of measurement of volumetric discharge of a
stream. To convert cms to CFS multiply by 35.3 cubic feet / cubic meter.
diffusion Transport which results from the random movement of molecules.
dispersion Transport of material in water through mixing. Dispersion always moves material
from locations with higher concentration to areas of lower concentration.
distribution number The product of unit concentration and duration. Often this dimensionless
number is nearly constant, and has a value slightly less than 2. R-TOT assumes a
constant value for the distribution number, and uses the duration, discharge, and spill
mass, along with this distribution number value, to calculate peak concentration.
R-TOT Program User’s Manual, June 1999 (revised) page 19
duration In R-TOT the duration of a spill is the length of time between the leading edge and
the trailing edge. Also termed the time-of-passage.
edge The time at which a concentration-time curve (observed or modeled) is at a percentage of
the peak concentration value. Values between 5-10% are used, with 7.5% a good
compromise if no value is given.
emulsion A stable colloidal suspension consisting of an immiscible liquid dispersed and held in
water.
entrainment The process in which a material is carried along by water flow. An entrained
material is not dissolved, but moves with the water flow in a manner similar to a solute.
estuary For the purpose of river mixing and spill modeling, the tidal part of a river.
Eulerian Referring to a fixed frame of reference which does not move along with water
movement (see Lagrangian). Named after Joseph-Louis Euler (1707-83), a great Swiss
mathematician and physicist.
Excel A spreadsheet application program published by Microsoft Corp. R-TOT 5 was
implemented under Excel for windows. Output of R-TOT 6 may be easily imported into
Excel (see section Importing R-TOT 6 output to a spreadsheet).
Fick's law This law states that the rate of change of concentration with time is proportional to
the second derivative of concentration with respect to distance. For molecular diffusion
in the x-direction the governing differential equation is:
.
∂𝑐
∂𝑡 =2𝑐
∂𝑥2
Fickian dispersion It is often assumed that dispersion can be modeled in a manner analogous
to molecular diffusion described by Fick's law.
gamma distribution A family of probability distribution functions which are skewed
(asymmetrical). The distribution has two parameters (compared to the Gaussian
distribution with only one parameter). Depending on parameter values the distribution
may vary from exponential to Gaussian. Also termed a Pearson type III distribution.
Lagrangian Referring to a frame of reference that moves along with water movement down a
river (see Eulerian). Named after the great Italian mathematician named Joseph-Louis
Lagrange (1736-1813).

leading edge The time at which a spill concentration is a small percentage, 5-10%, of the peak
concentration, and occurring before the peak.
mg/L Unit of concentration, milligram per liter. One mg/L is one thousand ug/L, and is

stage The surface elevation of a waterbody at a specific location.
surfacing The movement of a positively buoyant material to the water surface. This process
may occur in a river in areas of low velocity and turbulence.
tapedown A measurement from the water surface to a known mark on a fixed structure (a
scribe marked bridge rail, for example). As the measurement decreases water surface
elevation and therefore flow increases.
time-of-passage See duration.
trailing edge The time at which a spill concentration is a small percentage, 5-10%, of
the peak concentration, and occurring after the peak.
μg/L Unit of concentration, micrograms per liter. One thousand μg/L is one mg/L. One
part per billion, ppb, is approximately equal to one ug/L.
R-TOT Program User’s Manual, June 1999 (revised) page 21
unit concentration The peak concentration of a spill at a location and time scaled by
discharge and spill size. Unit concentration is the peak concentration multiplied
by discharge and divided spill weight. Often reported in common units of
(ug/L)-cfs/lb, the units may be reduced to reciprocal time.

Appendix 4: Pipeline locations on the Lower Mississippi River
This table presents locations for pipelines and other submerged and aerial crossings on the Lower
Mississippi River as miles (rivermiles) above Head-of-Passes (AHP). These data were extracted
from Corps of Engineers navigation charts. In R-TOT, enter these rivermile locations as negative
values. The east bank (E) is also referred to as the left descending bank, or simply the left bank.
The west bank (W) is also referred to as the right descending bank or simply the right bank. The
last column of the table provides vertical clearance in feet above high water for aerial crossings.
These data are provided only to assist R-TOT users in locating appropriate rivermile locations.

The Mississippi River is the source of drinking water for more than I million Louisiana residents. The river also is used for transportation of hazardous chemicals and petroleum products, and is the receiving stream for wastewater effluents from numerous industries and municipalities. To minimize the public's risk from contaminant spills and accidental discharges, drinking water providers need timely warning of approaching contaminants. Based on a modified plug-flow (MPF) formulation, a time-of-travel model has been developed to provide projections of the time of arrival, peak arrival time, time of passage, and duration of contaminant spills on the Mississippi River. Estimates of the peak concentrations of contaminants passing downstream locations are calculated from spill mass, discharge, and calculated duration. The model used for this research was calibrated using dye time-of-travel studies. The primary objective of this model is to facilitate the timely warning of drinking water providers. Additionally, this model may be of value in other water quality management applications, including contingency planning, impact assessment, monitoring, enforcement, and surveillance. KEYWORDS: time-of-travel, spill modeling, Mississippi River, modified plug-flow model, unit concentration, dye tracer studies.
