Show Final Report Hydrologic Model Analysis of the Provo River Basin • Conveyance losses and non- agricultural ( M& I) losses • Evaporation/ consumptive use calculations ( two methods) • Soil moisture accounting to calculate infiltration and groundwater return flows • Surface and subsurface return flows with variable targets and delay patterns Reservoir and Streamflow Operations • Pre- assigned rule curves ( or end- of- month target levels) • Tracking of demands and diversions for each water user • Accounting of river flows, diversions, gains, and available water in each reach • Accounting of water stored in and released from each account in each reservoir • Joint storage accounts in multiple reservoirs • Reservoir storage holdover and carryover accounting Other water rights, institutional arrangements, hydrological processes, and reservoir and streamflow operational rules can be added to the code as necessary to simulate new or proposed operating rules and conditions. Many of the hydrological processes can be adjusted based upon input from auxiliary runoff or groundwater simulation models. PROSIM can also be set- up to read inflow or demand data directly from the output of other models or to produce results that can be read directly by other models. 1.4 Relationship to Other Studies As stated previously, the Hydrologic Model Analysis of the Provo River Basin was conducted as one part of the completion plan for the Bonneville Unit of the CUP, which was in turn a part of the CUPCA, included in PL102- 575. Certain parts of the plan use results from the analysis documented herein, while others are being conducted independently. This Hydrologic Model Analysis relates to and may be used in the completion of the six Provo River/ Utah Lake Special Studies. The six studies, and their relationship to the Hydrologic Model Analysis of the Provo River are described in Table 1- 1. This Hydrologic Model Analysis is similar in certain ways, though broader in scope, to previous studies of the Provo River conducted by USBR and USGS to estimate the water supplies associated with the Municipal and Industrial System of the Bonneville Unit. These previous studies include the " Deer Creek Operation Study" and the " Jordanelle Operations Study," included in the USBR's 1988 " Supplement to Definite Plan Report"; and the " Review of Water Demand and Water Utilization Studies," ( USGS, 1991).
