Streamflow File - Daily (*.rid)
The daily streamflow file contains baseflows or a daily pattern for each day of the simulation period. To simplify the preparation of daily data,
StateMod allows the user to provide daily data or a pattern to be used with monthly data. When the daily river station variable crunidy is set to
3 the river station variable crunid is used to indicate daily data controls and any monthly data provided in the monthly streamflow file (*.rim or *.xbm)
is ignored. When the river station variable crunidy is set to any ID including its own StateMod uses daily data as a pattern to estimate daily data from
monthly data as follows:
Where:
\(Qd\) = daily estimated flow
\(Dp\) = daily flow (pattern)
\(Qm\) = monthly flow from the monthly flow file (*.rim)
\(Dm\) = monthly sum of daily flow (pattern)
This file is only required if the model is operated in a daily mode. Data can be entered with stations entered in any order. This file is read by subroutine DAYDATA.
