Book Description
Groundwater flow paths and flow rates through alluvium aquifers are often oversimplified. This oversimplification may be due to sediment description limitations or aquifer properties obtained using well hydraulics that assume homogeneity. Groundwater travel times to the Brazos River channel can be longer than anticipated when the aquifer gradient is low and flow paths encounter heterogeneity within the lithologic framework. Conversely, travel times to the river channel can be less than anticipated when gradients are steep and homogeneous coarse sediment dominate the lithology within the aquifer while connecting directly to the river. This thesis investigates unstressed groundwater flow rates and flow paths under natural conditions using detailed lithologic logs to recreate more realistic heterogeneity of the Brazos River Alluvium Aquifer characteristics and a 2D finite element steady state model. These estimations provide important insight for surface to groundwater interactions within alluvium aquifers.

Effluent-impacted Groundwater-surface Water Interactions in the Brazos River Alluvium Aquifer

Book Description
The primary recharge source to the Brazos River Alluvium Aquifer (BRAA), a water table aquifer in central Texas, is through direct precipitation on the floodplain. However, recharge provided by other sources, such as Brazos River tributaries crossing the alluvium is not well known. To quantify potential recharge from tributaries hydraulically connected to the BRAA and understand spatiotemporal interactions with the aquifer, Bullhide Creek was chosen due to its constant effluent discharge from a wastewater treatment plant and a 3-mile reach that interacts with the BRAA. Based on ionic and isotopic compositions, nutrient densities, and changes in flow measured throughout the studied reach, Bullhide Creek exhibits perennial streamflow after the wastewater contribution and gains flow from the BRAA during baseflow conditions. However, the creek may provide measurable recharge to the aquifer during periods of high flow through seepage to aquifer sediments adjacent to the channel and banks.
