Water Rights Analysis Package (WRAP) Modeling System

WRAP simulates management of the water resources of river/reservoir systems subject to priority-based water allocation. The modeling system 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 latest (August 2015) version of the software and manuals may be downloaded from this site along with input files for the examples in the manuals and descriptions of additions and revisions reflected in current and past versions.

WRAP is documented by Reference (2015), Users (2015), Fundamentals (2013), Daily (2015), Hydrology (2013), and Salinity (2009) Manuals. The manuals are published as Texas Water Resources Institute (TWRI) technical reports (TRs) and are also available along with other related TRs cited in the manuals at the TWRI website. Several of the other TWRI reports can also be downloaded from the download table below.

WRAP is incorporated in the Texas Commission on Environmental Quality (TCEQ) Water Availability Modeling (WAM) System. An array of WAM information including WRAP input datasets for all the river basins of Texas is accessible through the TCEQ WAM website.

The TCEQ WAM System and original WRAP are based on a monthly computational time step. The daily WRAP modeling capabilities described in the Daily Manual (TWRI TR-430) are still in a developmental test status. The case study daily version of WAM datasets and reports for the Brazos, Colorado, Trinity,  Neches, Sabine, and Guadalupe and San Antonio (GSA) River Basins accessible through the download table below are subject to further testing and revision. (These test versions of the daily WRAP input datasets will be added to this website during August 2015.)
