Oklahoma-Texas Water Science Center

Water information is fundamental to national and local economic well-being, protection of life and property, and effective management of water resources. USGS works with partners in Oklahoma and Texas to monitor, assess, conduct targeted research, and deliver information on a wide range of water resources including streamflow, groundwater, water quality, and water use and availability.

Flash drought: A state of the science review

In the two decades, since the advent of the term “flash drought,” considerable research has been directed toward the topic. Within the scientific community, we have actively forged a new paradigm that has avoided a chaotic evolution of conventional drought but instead recognizes that flash droughts have distinct dynamics and, particularly, impacts. We have moved beyond the initial debate over the

Watershed hydrology assessment for the Lower Colorado River Basin. Appendix D: RiverWare analyses

RiverWare is a river system modeling tool developed by CADSWES (Center of Advanced Decision Support for Water and Environmental Systems) that allows the user to simulate complex reservoir operations and perform period-of-record analyses for different scenarios. For the InFRM hydrology studies, RiverWare is used to generate a homogeneous regulated POR by simulating the basin as if the reservoirs an

Watershed hydrology assessment for the Lower Colorado River Basin. Appendix A: Statistical hydrology

Statistical analysis of the observational record from U.S. Geological Survey (USGS) streamgages and period of historical flow observations prior to the gage installation provides an informative means of estimating flood flow frequency. The U.S. Geological Survey contributed to the InFRM team’s efforts by performing the statistical analysis of the gaged record and authored this Appendix to the Lowe

Socio-Hydrology

The Oklahoma-Texas Water Science Center Socio-Hydrology Team conducts interdisciplinary studies spanning socioeconomic, hydrologic and climate science. Applying qualitative and quantitative approaches, we help stakeholders identify and assess a suite of water and climate risks. Our methodology provides a means for water and natural resource managers to analyze and evaluate risks, vulnerability...

Microplastics in Tributaries to Galveston Bay

Galveston Bay is the habitat of many organisms including many species of oysters, fish, and birds. USGS scientists from the Oklahoma-Texas Water Science Center are conducting a study, in cooperation with the Galveston Bay Estuary Program, to assess the occurrence and abundance of microplastics (plastic particles smaller than 5 mm in diameter) in Galveston Bay and its tributaries.

Urban Waters Federal Partnership - Edwards Aquifer Recharge in a Developing Landscape

San Antonio Texas consistently ranks as one of the fastest growing large cities in the United States. Urban development can affect groundwater quality as trees and open space are replaced by buildings and roads, increasing the amount of urban runoff draining directly into the Edwards aquifer. A network of sophisticated surface water and groundwater monitoring sites is being used to help managers...
