Guide to the cooperative mapping programs in the state of Texas administered by the USGS Texas Mapping Partnership Office. Provides description of ongoing projects with links to USGS and cooperator datasets for the state of Texas.
Examples of the use of Satellite Interferometric Synthetic Aperture Radar to measure and map changes on the Earth's surface as an aid to understanding how ground-water pumping, hydrocarbon production, or other human activities cause land subsidence.
Water from this reservoir will be used more extensively by the city, so we are developing methods of assessing the water quality in real time by measuring characteristics of stream flow that correlate with important water quality data.
The Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is conducting an analysis of historical shoreline changes along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii.
The area contributing recharge to this aquifer is undergoing rapid growth, generating more wastewater. We found that nitrate, a major component of wastewater and a nutrient that can degrade water quality, has increased in the creeks in this area.
Brief summaries of USGS projects in Texas including water quality monitoring, digital mapping, energy resources, U.S.-Mexico border mapping, fish and wildlife health, Kemp's Ridley sea turtle, and conditions affecting water quality.
We identified six compounds at concentrations less than human-health benchmarks, but within a factor of 10 of those limits. Those compounds might warrant further study to understand their transport and fate within the watershed.
