Creating a Standardized Watersheds Database for the Lower Rio Grande/Rio Bravo, Texas
Abstract
This report describes the creation of a large-scale watershed database for the lower Rio Grande/ Rio Bravo Basin in Texas. The watershed database includes watersheds delineated to all 1:24,OOO- scale mapped stream confluences and other hydrologically significant points selected watershed characteristics and hydrologic derivative datasets. Computer technology allows generation of preliminary watershed boundaries in a fraction of the time needed for manual methods. This automated process reduces development time and results in quality improvements in watershed boundaries and characteristics. These data can then be compiled in a permanent database eliminating the time-consuming step of data creation at the beginning of a project and providing a stable base dataset that can give users greater confidence when further subdividing watersheds.
