The researchers studied the Edwards aquifer in Texas to understand how water flows and is stored underground. They used a computer model to simulate different scenarios, like the effects of faults on water movement. The results showed that there are two separate areas where water flows in the aquifer, and they come together at Comal Springs. The direction of water movement is influenced by major faults in the area. The aquifer has high transmissivity values and a storage coefficient of 0.05 in some parts. Overall, the study helps us better understand how water moves through this important underground water source.
