Water Rights Analysis Package (WRAP) Modeling System
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 assessment of hydrologic and institutional water availability and reliability for specified water use requirements. Basin-wide impacts of water resources development projects and management strategies may be evaluated. The software package is generalized for application to any river/reservoir system, with input files being developed for the particular river basin of concern. The model is documented by Reference and Users Manuals, an introductory Fundamentals Manual, and a Supplemental Manual entitled Conditional Reliability, Sub-Monthly Time Step, Flood Control, and Salinity Features of WRAP.
The latest version of the software and four manuals may be downloaded from this site along with input files for the examples in the manuals and a description of modifications reflected in various versions of the model. The manuals are also available along with other technical reports at the Texas Water Resources Institute TWRI website. WRAP is incorporated in the Texas Commission on Environmental Quality (TCEQ) Water Availability Modeling (WAM) System. The Texas WAM System, including the WRAP model, datasets for the river basins of Texas, and related information, is accessible through the TCEQ WAM web site.
WRAP Users Group conferences are held each year in March and September. An interactive web-based Users Group forum for posting announcements and exchanging ideas is maintained as the FORUM website.
Comparative Evaluation of Generalized
River/Reservoir System Models
A state-of-the-art review of generalized reservoir/river management modeling systems including WRAP and other models may also be downloaded from this site. This report is designed to assist practitioners in selecting and applying generalized models in various situations and to support continuing research and development efforts in improving modeling capabilities.
