Description

The purpose of the study was to determine the change in storage of two water sheds after the impact of two rain events, considering factors such as rainfall, discharge and infiltration, and evapotranspiration. The two sub-watersheds, located on the Edward’s Aquifer Authority Field Research Park, each had a weir. The larger of the two watersheds was named Watershed 1, while the smaller one was named Watershed 2. Watershed 1 was where the weir named Arnold was located, while watershed 2 was where the weir named Danny was located. Inflow and outflow were calculated by analyzing precipitation data and water flow data provided by the EAA. Outflow in low flow conditions was calculated using measurements taken during the onsite visit.

This report is a summary of the work of the Fall 2025 Physical Hydrogeology course at St. Mary’s University. There were two teams of students in the class who worked on the project as independent groups titled Team Rattler and Team StMU. For this reason, results are reported in the report for each group along with the values calculated by the instructor, Evelynn Mitchell, PhD, and an average value for each category. The Executive Summary reports the average values as the findings of the report.
