Estimating Potential Effects on Streamflow from Nearby Wells in the Lower San Antonio River Basin
The USGS Oklahoma-Texas Water Science Center (OTWSC) developed a groundwater-flow model to estimate the potential for streamflow depletion in the Lower San Antonio River based on changes in groundwater pumping in the watershed. Results from the project can be used by the San Antonio River Authority (SARA) to better understand aquifer interactions with the river and potential groundwater pumping...
Monitoring Science in Oklahoma and Texas
USGS Oklahoma-Texas Water Science Center (OTWSC) monitoring studies collect data to provide reliable, unbiased scientific data to support water needs across Texas. OTWSC collects real-time streamflow, groundwater, and water-quality data through a network of over 850 real-time gages across the state. These gages provide a consistent, long-term record of water trends. OTWSC scientists also collect...
Oklahoma-Texas Water Data for Emergency Management
Emergency managers often have urgent needs for situational awareness, impact assessment, and management of recovery or mitigation activities. Collecting and delivering information where and when it is needed requires advanced planning. The USGS Oklahoma-Texas Water Science Center (OTWSC) can monitor water conditions anywhere but we must have the equipment in place before the event. The OTWSC can...
Interagency Flood Risk Management (InFRM)
In 2014, the Federal Emergency Management Agency (FEMA) began sponsorship of the InFRM team initiative to allow Federal teams across the States of Texas, Oklahoma, New Mexico, Louisiana and Arkansas to better align and integrate. Currently, the InFRM team is comprised of FEMA, US Army Corps of Engineers, US Geological Survey, and the National Weather Service. Information about the Interagency...
Edwards Aquifer Groundwater Model Uncertainty Analysis
USGS Oklahoma-Texas Water Science Center (OTWSC) is undertaking a 1.5-year study to assess parameter and predictive uncertainty in the Edwards Aquifer Authority MODFLOW Model using both linear and non-linear techniques. The Edwards Aquifer Authority (EAA) uses two models simulating the periods from 2001 to 2015 (verification model) and the drought of record of 1947-1958 (drought of record model).
Cyanobacteria Methods
Oklahoma-Texas Water Science Center (OTWSC) scientists are testing different methods of detecting and quantifying cyanobacteria and cyanotoxins in Texas reservoirs. The results of these tests could be used to develop a cost-effective monitoring plan to evaluate the presence and concentration of cyanobacteria and cyanotoxins in Texas reservoirs.
Coastal Lowlands Regional Groundwater Availability Study
USGS is undertaking a 5-year study to assess groundwater availability for the aquifers proximal to the Gulf of America from the Texas-Mexico border through the panhandle of Florida, known as the Coastal Lowlands Aquifer System (CLAS). This study is one of several within the Regional Groundwater Availability Studies of the USGS Water Availability and Use Science Program.
Water Budget Science in Oklahoma and Texas
A water budget is an accounting of hydrologic components of the water cycle, transfers between the components, and their relative contributions within a water system. Water budgets help define how much water is available, how much water is used, where the water comes from, and at what rate water is replenished or consumed. In its simplest form, a water budget defines the amount of water entering...
Surface-Water and Groundwater Interaction Science in Oklahoma and Texas - Overview
Surface-water/groundwater interactions include the exchange of water, and the chemicals that may be present in the water, which can lead to issues with water supply and water quality. Groundwater can be a major contributor to streams, lakes, and wetlands while surface water can contribute recharge to groundwater. The USGS Oklahoma-Texas Water Science Center (OTWSC) uses geophysics and other...
Subsidence Science in Oklahoma and Texas - Overview
The USGS Oklahoma-Texas Water Science Center (OTWSC) has researched land-surface subsidence for more than 40 years. OTWSC collects and interprets groundwater level and aquifer sediment compaction data to understand the effects of groundwater withdrawal on land surface subsidence.
USGS Research: PAHs and Coal-Tar-Based Pavement Sealcoat
Coal-tar-based pavement sealant is a potent source of polycyclic aromatic hydrocarbons (PAHs), as documented by the USGS and other researchers. Coal-tar-based sealcoat products typically are 20 to 35% coal tar or coal-tar pitch—these materials are known human carcinogens that contain high concentrations of PAHs and related chemicals. Coal-tar-based pavement sealcoat typically contains 35,000 to...
Sediment Science in Oklahoma and Texas
The U.S. Environmental Protection Agency (EPA) has identified sediment as a leading cause of impairment in the Nation’s rivers and streams. Excessive sedimentation degrades aquatic habitat; reduces longevity of water-supply, flood-control reservoirs; and is the primary transport mechanism of toxic organic chemicals, heavy metals, and nutrients. The USGS Oklahoma-Texas Water Science Center (OTWSC)...
