Survey level data for two cross-sections in a 23-mile reach of the Medina River at Bandera, Texas, 2017

Digital flood-inundation maps were created by the U.S. Geological Survey (USGS) in cooperation with the Bandera County River Authority and Groundwater District and with the Texas Water Development Board for a 23-mile reach of the Medina River extending from Winans Creek to English Crossing, Texas. The flood-inundation maps represent a range of selected water-surface elevations at USGS streamflow-gaging station 08178880 Medina River at Bandera, Texas (hereinafter referred to as the “Bandera station”). In this study, flood profiles were computed for the stream reach by means of a one-dimensional step-backwater model HEC-RAS (Hydrologic Engineering Center River Analysis System) (Davidian, 1984; U.S. Army Corps of Engineers, 2016a, b).
