<br />. TaSkIDa-7 <br /> <br />Software IkVelopment for Year 3 Basin lrrihancement <br /> <br />Objective: The RTi software development group lead by Steve Maiers will perform the enhancement <br />of the existing CRDSS utilities to facilitate the water resources modeling groups efforts in enhancing <br />the CRDSS water resource planning models to account for 100 % of the water use in the basin. <br />Software enhancements scope and schedule are designed to facilitate work on the White River Basin, <br />but enhancements are envisioned, where possible to do so, for all the basins. <br /> <br />Task Manager: Steve Maiers <br /> <br />Task 7.01 Modify Watright to Aggregate Diversion Station and Diversion Rights <br /> <br />Objective: Modify the watright utility to generate StateMod direct diversion station and water <br />rights files for aggregated agricultural demands using the water rights aggregation classes <br />determined in Task 2,04, <br /> <br />. <br /> <br />Approach: <br />1. RTISW: Modify watright to take as input a group ofWDlD's that represent all the <br />structures to be aggregated and generate a full list of net absolute water rights in the diversion station <br />rights file (.ddr). The implementation will use commands file arguments similar to: aggregate <br />(AGG_NOOE_lD, WDlD, WOlD,...), As in Phase II, watright will in general expect to read a river <br />network file generated by makenet in order to determine the list of structures in the model. A <br />make net-generated river network file contains the structure identifier in the comment field which <br />allows watright to correctly access the database for that structure, The version ofwatright resulting <br />from this task will therefore be able to generate diversion station and rights files where spatial <br />aggregation but no water rights aggregation has occurred, This will be useful to help verify the <br />water rights aggregation (see next Task), to allow water rights to be explicitly modeled if so desired, <br />and to allow performance and sensitivity tests of water rights aggregation versus non-aggregation, <br />2, RTISW: Modify watright to calculate the aggregated structure capacity as the sum of the <br />individual capacities of the structures being aggregated and calculate the aggregated irrigated acreage <br />as the sum of the acreage's of the individual structure acreage's. Default information and return flow <br />patterns will be handled as implemented for the Phase II work, As such, data editing command-line <br />options such as "setdiv" will still be enabled on the aggregate structures, <br />3. RTISW: Modify watright to perform water rights aggregation based on water rights <br />classes. For example, implement a command line option similar to -wrclass(admin #1, admin <br />#2,.....) which would indicate the break-points of admin numbers within the entire data set being <br />used. Conventions on how the water rights will be divided will be agreed on and will be handled <br />consistently (e,g" break classes at >= and < the class admin numbers). No aggregation will occur if <br />water rights classes are not specified (the equivalent of the previous Task), The water rights classes <br />will be the result of aggregation studies done in Tasks 2 through 6. The following steps will be <br />performed: <br />. Get the absolute water rights for all the structures in the aggregate list. Net absolute <br />values will be taken from a table in the database and will not be calculated on the fly. <br /> <br />. <br /> <br />1142 <br /> <br />Phase II1a Scope of Services <br /> <br />A.43 <br /> <br />Jan31,1997 <br />
