South Central Texas depends on deep seated aquifers to maintain a water supply for over 5 million people. Much of this water supply is recharged through karst features in the Texas Hill Country. Understanding the features on a property helps determine the appropriate level of development, but geophysical methods have limitations on interpreting feature size. Students in this project built on previous work to examine the error of two common geophysical methods when detecting humanly accessible shallow karst features. They gained skills in site analysis using spatial software and high-resolution GPS collection, field work planning, data collection and analysis.
