4.19 - Daily Historical Diversion File (*.ddy)
The daily historical diversion file (*.ddy), provides historic daily diversions for a list of structures.
Water supply contained in the daily historical diversion file (*.ddy) represents river headgate diversions,
not the supply delivered to the crop. Daily diversions must sum to the monthly diversions used in the monthly
historical diversion file (*.ddh). When the user chooses to process daily diversions by priority (
see Section 4.4), the StateCU uses the daily diversion file to determine the percent of monthly diversions
(in the *.ddh file, see Section 4.13) that are senior or junior to the user input administration number(s).
Missing data is accepted using a –999 placeholder. The file can contain more structures than defined by the
structure location file (*.str), but must include all structures being simulated. Likewise, the total years
can be more than the study defined in the model control file by
nyr2 (see Section 4.4).
|Row 1||Format (i5, 1x, i4, 5x, i5, 1x, i4, a5, a5)|
|1-1||ibm||Beginning month of data (e.g. 1=Jan)|
|1-2||iby||Beginning year of data (e.g. 1975)|
|1-3||iem||Ending month of data|
|1-4||iey||Ending year of data|
|1-5||cunit||Units of data ('CFS')|
|1-6||cyr||Year type, CYR is calendar year or WYR is water year|
|Row 2||Format (i4, i4, 1x, a12, 31f8.2, f8.0)|
|2-3||cdividx||Daily station ID|
|2-4||diverdx(i)||Historic diversion (cfs) or pattern, i=1,31|
Repeat for the number of structures.
Repeat for each year of the simulation.
