Geospatial and survey data for flood-inundation maps in a 23-mile reach of the Medina River at Bandera, Texas, 2018

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”). Near-real time hydrologic data for estimating areas of inundation near the Bandera station are available from the USGS National Water Information System (NWIS) web interface (https://waterdata.usgs.gov/tx/nwis/) and from the National Weather Service (NWS) Advanced Hydrologic Prediction Service (http:/water.weather.gov/ahps/). In this study, flood profiles were computed for the stream reach by means of a one-dimensional step-backwater model (Davidian, 1984; U.S. Army Corps of Engineers, 2016a, b). These digital data accompany Choi, N., and Engel, F.L., 2019, Flood-inundation maps for a 23-mile reach of the Medina River at Bandera, Texas, 2018: U.S. Geological Survey Scientific Investigations Report 2019-5067, 15 p., https://doi.org/10.3133/sir20195067. Detailed information about the methods and data used for this analysis are provided in the companion interpretive report. The flood-inundation maps can be accessed through the USGS Flood Inundation Mapping Science website at http://water.usgs.gov/osw/flood_inundation/.
