Flood Early Warning System

Flood Early Warning System

“Floods are the leading cause of natural-disaster losses in the United States. Although loss of life to floods during the past half-century has declined, in part because of improved warning systems, economic losses have continued to rise with increased urbanization in flood-hazard areas throughout the Nation (U.S. Geological Survey, 2006).”

screen-shot-2016-11-28-at-4-00-17-pmBandera County River Authority and Groundwater District (BCRAGD) was awarded grant funds from the Texas Water Development Board (TWDB) for the installation of an Flood Early Warning System (FEWS) on the Medina River. The USGS will be developing a flood warning tool set for use by Bandera County Emergency Services and the general public during rainfall events. There will be additional gauges and high-intensity rainfall gauges installed, from which a hydraulic model will be developed to create a flood atlas and an interactive flood inundation map that has predictive properties.

Along with the grant funds provided by the TWDB, contributions have also been made by Bandera County government, and the Economic Development Committee from the City of Bandera.

The grant was awarded for a three-year period of funding, at which time a formal report will be submitted to the TWDB on the development and success of the Flood Early Warning System (FEWS). Within those three years BCRAGD will be hosting public meetings to discuss the development of the project and to give updates. The dates and times for the public meetings will be posted on the BCRAGD website.
