Science and Products
Estimating Potential Effects on Streamflow from Nearby Wells in the Lower San Antonio River Basin
The USGS Texas Water Science Center (TXWSC) 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 effects on...
Edwards Aquifer Groundwater Model Uncertainty Analysis
USGS Texas Water Science Center (TXWSC) 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).
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 Mexico 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...
Modeling Science in Oklahoma and Texas
Models provide the capability to simulate scenarios of possible future conditions and management options to help water-resource professionals with planning decisions. Groundwater models are commonly used to evaluate changes to the water budget of an aquifer resulting from land-use changes, water withdrawals, and climate, and how these changes affect streamflow, lake levels, water quality, and...
Edwards Aquifer Studies in Texas
The Edwards aquifer in south-central Texas is one of the most productive aquifers in the Nation and is the primary source of water for the rapidly growing San Antonio area. Springs issuing from the Edwards aquifer provide habitat for several threatened and endangered species, serve as locations for recreational activities, and supply downstream users. The USGS Oklahoma-Texas Water Science Center...
Groundwater Modeling at the Oklahoma-Texas Water Science Center
The Oklahoma-Texas Water Science Center performs computer simulations using MODFLOW to simulate groundwater/surface-water interaction, quantify groundwater resources, and evaluate the effects of withdrawals on future groundwater supplies for aquifers in Oklahoma and Texas.
