Historic Diversion File - Daily (*.ddy)
The daily historic diversion file contains diversions 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 diversion station variable cdividy is set to 3 the diversion
station variable cdivid is used to indicate daily data controls and any monthly data provided in the monthly
direct flow demand file (*.ddm) is ignored. When the diversion station variable cdividy is set to any ID including
its own (cdivid) StateMod uses daily data as a pattern to estimate daily data using the same approach described
under daily streamflow data (Section 4.36).
This file is only required if the model is operated in a daily baseflow mode. Data can be entered with stations
entered in any order. This file is read by subroutine DAYDATA.
