Overview

The CalculateStreamEstimateCoefficients command (for StateMod) calculates stream estimate coefficients for each stream estimate station that is in memory – the previous values will be overwritten. If SetStreamEstimateCoefficientsPFGage commands are used, they should be specified before this command. Conversely, SetStreamEstimateCoefficients commands, if used, should be provided after this command.

Command Editor

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

Command Syntax

The command syntax is as follows:

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

Command Parameters

Parameter	Description	Default
	Currently, this command has no parameters.

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
