Description
Summary:The U.S. Army Engineer District, Fort Worth (CESWF) is involved in demon- strating the utility of an ecological model in the performance and interpretation of a comprehensive General Investigations (GI) study of the Cibolo Creek watershed upstream of Interstate 10 near San Antonio, Texas. Partners to the District in this project are the Natural Resources Conservation Service (NRCS), U.S. Geological Survey (USGS), and U.S. Fish and Wildlife Service (USFW). Project sponsors are the Guadalupe-Blanco River Authority (GBRA), San Antonio River Authority (SARA), and San Antonio Water System (SAWS). CESWF requested assistance from the U.S. Army Engineer Research and Development Center (ERDC) in conducting this study. The first phase of the study was to establish existing conditions of the hydrologic, engineering, economic, and environmental aspects of the study area, and to demonstrate watershed modeling tools. The second phase will evaluate a recharge/dry detention structure to identify the relative magnitude of the structure's flood damage reduction and aquifer recharge benefits. The third phase will formulate and screen alternatives to meet national and local plans regarding detention structures, restoration of aquatic habitats and hydrology, reforested riparian and wetland buffer zones, creation of emergent wetlands, brush management techniques, watershed policies dealing with urban/suburban growth, and nonstructural flood damage reduction. During the first phase, researchers at ERDC set up and demonstrated the ecological model. Implementation of the second phase is dependent on evaluation of the first phase by the sponsors.
