WRAP is documented by six manuals that can be downloaded below as PDF files. The manuals are published as Texas Water Resources Institute (TWRI) technical reports (TRs) and are also available along with other TRs cited in the WRAP manuals at the TWRI website.
Reference Manual (TWRI TR-255, July 2022, 464 pages)
Users Manual (TWRI TR-256, July 2022, 274 pages)
Fundamentals Manual (TWRI TR-283, July 2022, 116 pages)
Daily Manual (TWRI TR-430, July 2022, 346 pages)
Hydrology Manual (TWRI TR-431, May 2019, 241 pages)
Salinity Manual (TWRI TR-317, July 2009, 89 pages)
Examples presented in the manuals illustrate the concepts and methods covered. The Fundamentals Manual is organized around an example applying the WRAP programs WinWRAP, SIM, and TABLES and the USACE Hydrologic Engineering Center (HEC) program HEC-DSSVue. Some of the examples in the other manuals build upon and extend the example in the Fundamentals Manual. The input datasets for the examples in the manuals can be downloaded from a Microsoft OneDrive site through the link provided below.
In some cases other relevant datasets associated with the examples are included along with the input datasets for the WRAP programs. All of the data files for the examples in all of the manuals can be downloaded together as a single zip file with filename WRAPexamples.zip. Alternatively, datasets for each of the different manuals can be accessed and downloaded separately.
Development, improvement, and expansion of WRAP has occurred over many years and versions. An Additions and Revisions Report describes the modifications to WRAP that have occurred over various periods of time.
