TWRI grant recipient studies groundwater input to the Brazos River

By Caitlin Churchill

Rice University graduate student Fanwei Zeng is earning her doctorate in biogeochemistry as she works with her advising professor Dr. Carrie Masiello to test using carbon isotopes as a tool to estimate groundwater input from carbonate-containing aquifers to rivers. For this project, she measured dissolved inorganic carbon in the Brazos River.

Zeng, a native of China and graduate from the University of Science and Technology of China, is a recipient of a 2007-08 Texas Water Resources Institute (TWRI) research grant. With the $5,000 research grant, Zeng said she found that carbonate input to rivers can be detected using carbon isotopes. However, she is not yet ready to apply these carbon isotopic techniques to estimate groundwater. More research on the input of carbonate from surface water and interflow runoff and atmospheric carbon dioxide is needed, she said.

AgriLife Research, Extension to investigate Cowhouse Creek conservation practices

A team of Texas AgriLife Research scientists and Texas AgriLife Extension Service specialists has received a $647,000 federal grant to evaluate the impacts of conservation practices within the Cowhouse Creek watershed in Central Texas.

“The purpose of our efforts will be to understand how specific conservation practices affect the watershed’s overall health and landscape,” said Dr. Bradford Wilcox, the AgriLife Research rangeland specialist who is leading the project.

The three-year grant is funded by the U.S. Department of Agriculture-Cooperative State Research, Education and Extension Service. Counties included in the study are Hamilton, Coryell and Bell counties.

“Results from this project will provide agencies and landowners with an understanding of how alternative conservation practices, timing of implementation and distribution of conservation efforts impact grazing lands and assist in achieving watershed health goals,” said Dr. Bill Fox, assistant professor with the Blackland Research and Extension Center in Temple and project researcher.

Arroyo Colorado partnership installs watershed road signs

The Arroyo Colorado Watershed Partnership recently installed 10 road signs marking the boundary of the Arroyo Colorado watershed in the Lower Rio Grande Valley as part of the partnership’s ongoing efforts to restore and protect the watershed. The Arroyo Colorado, which runs 90 miles from Mission to the Lower Laguna Madre, is on the state’s list of impaired waters for high bacteria levels and low dissolved oxygen.

In addition to the signs installed by the partnership, several local cities are also installing more signs to mark either the watershed boundary or an Arroyo Colorado crossing, said Jaime Flores, Arroyo Colorado watershed coordinator. The city of McAllen is installing two additional signs and other cities in the watershed, as part of the Lower Rio Grande Valley Stormwater Task Force, will install more later.
