Identifying Opportunities to Strengthen Climate Resilience in Flood-Prone Underserved Communities in Harris County, Texas
Flooding in urban centers caused by increasingly severe storms has led to massive economic, social, and ecological damage. Researchers supported by this South Central CASC project will examine flood vulnerability and equity in mitigation efforts in Harris County, Texas, currently home to the highest concentration of federally funded relocation projects in the country. The resulting flood vulnerabi
Flood-inundation maps created using a synthetic rating curve for a 10-mile reach of the Sabinal River and a 7-mile reach of the West Sabinal River near Utopia, Texas, 2021
In 2021, the U.S. Geological Survey (USGS), in cooperation with the Bandera County River Authority and Groundwater District and the Texas Water Development Board, studied floods to produce a library of flood-inundation maps for the Sabinal River near Utopia, Texas. Digital flood-inundation maps were created for a 10-mile reach of the Sabinal River from USGS streamgage 08197936 Sabinal River below

Flood warning toolset for the Sabinal River near Utopia, Texas
IntroductionFloods are one of the most frequent and expensive natural disasters that occur across the United States. Rapid, high-water events that occur in local areas—flash floods—are especially difficult for emergency managers to predict and provide advance warning to the public, and insufficient data can hamper postflood recovery efforts. Central Texas is hilly, and it is known as a “flash floo

Flood-inundation maps for a 23-mile reach of the Medina River at Bandera, Texas, 2018
In 2018, the U.S. Geological Survey (USGS), in cooperation with the Bandera County River Authority and Groundwater District and the Texas Water Development Board, studied floods through the period of record to create a library of flood-inundation maps for the Medina River at Bandera, Texas. Digital flood-inundation maps for a 23-mile reach of the Medina River at and near Bandera, from the confluen

Flood warning toolset for the Medina River in Bandera County, Texas
OverviewFloods are the most common natural disaster in the United States. The Medina River in Bandera County, Texas, is in the Edwards Plateau, where high-intensity rain rates and steep terrain frequently contribute to severe flash flooding capable of causing loss of life and property. For example, the July 5, 2002, flood claimed a total of 12 lives in the central Texas area. The estimated peak di
