StateDMI / Command / SetStreamEstimateCoefficients

Overview

The SetStreamEstimateCoefficients sets data in existing stream estimate coefficients – the previous values will be overwritten. If base or gain data are specified, the original values will be replaced (not appended).

Command Editor

The following dialog is used to edit the command and illustrates the command syntax.

Command Syntax

The command syntax is as follows:

SetStreamEstimateCoefficients(Parameter="Value",...)

Command Parameters

Parameter               Description Default          
ID A single stream estimate station identifier to match or a pattern using wildcards (e.g., 20*). None – must be specified.
ProrationFactor The proration factor for all matching stream estimate stations. If not specified, the original value will remain.
BaseData The base flow coefficient and station ID pairs to be assigned for all matching stream estimate stations. Repeat for as many pairs as necessary, separated by commas. If not specified, the original value will remain.
GainData The gain flow coefficient and station ID pairs to be assigned for all matching stream estimate stations. Repeat for as many pairs as necessary, separated by commas. If not specified, the original value will remain.
IfNotFound Used for error handling, one of the following:
  • Add – add the stream estimate coefficients if the ID is not matched and is not a wildcard
  • Fail – generate a failure message if the ID is not matched
  • Ignore – ignore (don’t add and don’t generate a message) if the ID is not matched
  • Warn – generate a warning message if the ID is not matched
 Warn

Examples

See the automated tests.

The following command file illustrates how a StateMod stream estimate coefficients file can be created:

StartLog(LogFile="rib.commands.StateDMI.log")
# rib.commands.StateDMI
#
# Creates the Stream Estimate Station Coefficient Data file
#
#  Step 1 - read river nodes from the network file and create file framework
#
ReadStreamEstimateStationsFromNetwork(InputFile="..\Network\cm2005.net")
#
#  Step 2 - set preferred gages for "neighboring" gage approach
#           this baseflow nodes are generally on smaller non-gaged tribs and have
#           different flow characteristics than next downstream gages
#
SetStreamEstimateCoefficientsPFGage(ID="360645",GageID="09055300")
...similar commands omitted...
#
#  Step 3 - calculate stream coefficients
CalculateStreamEstimateCoefficients()
#
#  Step 4 - set proration factors directly
#
SetStreamEstimateCoefficients(ID="364512",ProrationFactor=1.000,IfNotFound=Warn)
...similar commands omitted...
#
#  Step 5 - create streamflow estimate coefficient file
#
WriteStreamEstimateCoefficientsToStateMod(OutputFile="..\StateMOD\cm2005.rib")
#
# Check the results
CheckStreamEstimateCoefficients(ID="*")
WriteCheckFile(OutputFile="rib.commands.StateDMI.check.html")
