Pumpage from the aquifer is distributed according to the 1989 data on monthly pumpage by cell and by use. The DSS pre-processor enables users to select and edit information on recharge and pumping in the system's database. Estimates of monthly recharge can be edited as a percentage or amount. Monthly pumpage can be edited as a percentage or amount, according to changes in municipal, industrial, irrigation, or domestic use. Once processing is complete, the DSS provides users with flows or heads at selected sites.
Users can specify any cell or combination of cells to observe results.
Outputs from the DSS include graphs and tables that can be exported to spreadsheets. A major advantage of the DSS is that it eliminates the need for users to develop an extensive database required to interface with a complex simulation model. A Pentium PC running at 166 mhz requires less than one minute to access the database, build input files, run the model, construct the output files, and develop output graphics for one year. The DSS does not allow users to change the model or database from current configurations. The DSS is now being utilized by the San Antonio Water System and the Guadalupe-Blanco River Authority.
