Brian R Clark
Brian Clark is the Deputy Program Coordinator for the Water Availability and Use Science Program in the USGS Water Resources Mission Area.
Brian has led water resource investigations of groundwater and surface water computer model simulations in 12 States and six Countries. He recently served as the Geographic Information Specialist at the USGS providing support for database construction, project management planning, and web-application design. He has also served as adjunct faculty at the University of Arkansas at Little Rock as Instructor of Hydrogeology.
Brian has authored or co-authored over a dozen USGS reports and has presented various work at over 19 professional conferences for 13 entities in 11 States with audiences ranging from students and water resource managers to an Army Colonel and Brigadier General.
Brian began his career in water resources at a water well construction company in northwest Arkansas installing submersible pumps and drilling wells for domestic and municipal use. He attended Arkansas Tech University, receiving a Bachelors of Science in Physical Science in 1998. While at Arkansas Tech, his interest in subsurface structure and processes led to a minor in geology where Dr. Steve Kline, Associate Professor of Geology, took the initiative to convince Brian to apply to graduate school.
While at Baylor, Brian served as the both lab instructor and manager of the department drill rig. Opportunities outside the classroom while at Baylor included investigations into the efficiency of municipal water transport for the City of Dallas, a gas pipeline survey on Big Sandy Creek north of Beaumont, and the application of geophysical methods within a salt dome 1,500 feet below land surface. Brian graduated from Baylor with a Masters in Geology in 2000.

Groundwater or surface water interaction in the Ozark Plateaus aquifer system. Includes examples of thermal imagery used to see groundwater entering streams.
In 1986, Congress directed the USGS to regularly report groundwater-level changes in the High Plains aquifer system. To comply with this directive, the USGS compares water levels measured every two years. By measuring water levels across the entire aquifer in one year, measurements made two years later enable calculation of changes over time.

The USGS recently constructed a computer model of groundwater in the Mississippi embayment. This model was used to simulate the rise or decline of water level in a deep aquifer. Water from this deep aquifer is utilized to meet the industrial and public supply needs in the area.

The USGS recently constructed a computer model of groundwater in the Mississippi embayment. This model was used to simulate the rise or decline of water level in a shallow aquifer. Water from this shallow aquifer is utilized by the agricultural based economy in the area.

A groundwater-flow model of the Mississippi embayment was used to evaluate changes in water-level altitudes after the addition of wells that simulate potential future pumping from the Sparta aquifer in the Bayou Meto-Grand Prairie area of eastern Arkansas (shown within the black outline) for the 30-year period from 2007 through 2037.

As the animation begins, the land surface of the Mississippi embayment fades away to reveal underground geologic formations (shown as shades of blue, brown, and gray surfaces). A slice deep into the earth cuts off the eastern half of the embayment so we can peer into the formations (aquifers) beneath the surface.

Water, oil, and gas wells (shown as green lines) are drilled to hundreds or thousands of feet below land surface in an area known as the Mississippi embayment. Information gathered from these wells was used to create a 3D computer model of underground formations.

Mississippi Embayment Aquifer System Regional Groundwater Availability Study
The US Geological Survey (USGS) is conducting large scale multidisciplinary regional studies of groundwater availability for the Nation. Studies comprise individual assessments, like the Mississippi embayment, of regional groundwater flow systems that cover a variety of hydrogeologic terrains and are used to develop a comprehensive regional and national perspective.
Mississippi Alluvial Plain (MAP) Regional Water Availability Study
The Mississippi Alluvial Plain (MAP) has become one of the most important agricultural regions in the US, and it relies heavily on a groundwater system that is poorly understood and shows signs of substantial change.
