" . " demandts will be roo in batch mode (e.g., by reading a STATEMOD diversion stations file, looking for corresponding demand time series in consumptive use model output, and reformatting the consumptive use output for STATEMOD). The demandts utility will have no graphical scenario selector and will operate on file paths only. I. Write a low-level DM!" routine to retum the headgate associated with an irrigated parcel of land (and vice versa). Given a list of key structures (given in a control file and/or determined from the INFORM IX database), write routines to read and process consumptive use demand time series from the consumptive use model output, and format the time series for STATEMOD. The identifiers for the time series will be preserved in performing the translation. 2. Write routines to convert the CRSM flows and reservoir end of month storages to STATEMOD time series. The end of month storages can be imposed as target storage time series within STATEMOD. Routines already exist for reading CRSM time series from TAPEDIT output as do generic routines for outputting ST A TEMOD time series; however, additional work needs to be done to integrate a single time series in a large STATEMOD file. (Routines do not exist for reading the CRSM hydrology files; routines would need to be written if that data were to be accessed for some reason instead of the USGS flows in the INFORMIX database.) Consequently, this subtask would involl'e piecing together calls to existing routines and mapping CRSM time series identifiers to STATEMOD identifiers. The program logic would also have to recognize scenarios so that modifications to the correct ST A TEMOD scenario files are made. It is assumed that a CRSM data set (or sets) will be made available under Task 2.08 that contains the appropriate TAPEDIT control file (or files) for outputting reservoir end of month storage and flow time series in a straightforward manner, 0') an ~ .-j 3. Write routines to subtract the CRSM flows at a USGS station from the STATEMOD base flows at the same station to provide a demand adjustment time series in STATEMOD format. This demand adjustment will account for the diversions left in the gage in the STATEMOD data. Routines already exist for reading CRS:-'1 output time series, A routine will need to be written to read STATEMOD time series files. Routines already exist for subtracting time series and outputting STATEMOD time series. Consequently, this subtask will consist mainly of coordinating input/output by mapping CRSM time series identifiers to STATEMOD identifiers and merging/overwriting single time series within the STATEMOD time series files. The program logic will also have to recognize scenarios so that modifications to the correct STATEMOD scenario files are made. 4. Write. routines to convert STATEMOD output river flow time series to consumptive use time series format to be used as available water supply input to the consumptive use model. A routine will need to be written to read the STATEMOD output time series. Another routine will need to be written to output time series for the consumptive use model. If necessary, the existing consumptive use time series format will be modified to be made more flexible, The program logic will also have to recognize scenarios so that modifications to the correct consumptive use scenario files are made. Subtask 3, Design and implement an improl'ed watright DMI utility program, The watright utility will be executed via the UNIX command line. Information will be supplied to the program using command line arguments and supporting data files, The utility will not have a GUI but will be accessible from Mosaic as part of the historical data displays being developed in Task 2.07. The Mosaic interface will consist of basic viewing capabilities including the following: DRAFT .020 O/,17.VJ A-41
