Assessing surface and groundwater interactions between the middle Brazos River Alluvium Aquifer and the Brazos River.

The Brazos River Alluvium Aquifer (BRAA) is a vital source of water in Central Texas, primarily used for irrigation. The BRAA and the overlying Brazos River are connected; however, their interaction is not well understood and often overgeneralized. This study seeks to clarify aspects of surface water groundwater (SW/GW) interactions in the middle segment of the BRAA. Regional modeling of the BRAA has been guided by the Texas Water Development Board (TWDB); however, current models have not accounted for the aquifer heterogeneity and/or included the variability of SW/GW interactions. This study uses original data in the context of historical data to better define hydrogeologic gradients, chemical composition, and flow variation in the middle segment of the BRAA. Results show a generalized hydrogeologic gradient from the BRAA to the Brazos River with temporary reversals, near the river, during periods of increased river discharge and higher channel water levels.
