return_flow: Return Flow

In FlowWest/cvpiaFlow: Modeled Flow Data for the CVPIA SIT Model

Description

A dataset containing the proportion flows at tributary junction coming from natal watershed using October CALSIM II flows. These proportions are used to estimate straying in the CVPIA SIT Salmon Population Model.

Usage

return_flow

Format

dataframe with 31 rows and 83 variables:

watershed

31 CVPIA watersheds

date

CALSIM II date

retQ

proportion of flow at tributary junction from natal watershed in October

Details

The return flow proportion is calculated using the average October flow in each watershed divided by the average October flow of the tributary it flows into for each year of the simulation. These tributary relationships are described in detail below.
