abstract
The Water Rights Analysis Package (WRAP) simulates management of the water resources of a river basin or multiple-basin region under a priority-based water allocation system. The model facilitates assessments of hydrologic and institutional water availability and reliability in satisfying requirements for instream flows, water supply diversions, hydroelectric energy generation, and reservoir storage. Basin-wide impacts of water resources development projects and management practices are modeled. The Texas Commission on Environmental Quality (TCEQ), its partner agencies, and contractors implemented a statewide Water Availability Modeling (WAM) System based on WRAP during 1997-2003 pursuant to comprehensive water management legislation enacted by the Texas Legislature in 1997. Expanded modeling capabilities developed since implementation of the Texas WAM System are designed to support a broader range of decision support needs as well as better address issues identified during implementation of the WAM System. Recent extensions to WRAP involve adding (1) conditional reliability modeling capabilities, (2) daily time step features including flow forecasting and routing, (3) features for simulating flood control operations, and (4) a salinity simulation component.
