AQUIFER SUSTAINABILITY: MODERN METEOROLOGICAL DATA GENERATES MORE ACCURATE RECHARGE CALCULATIONS
To ensure the most accurate representation of meteorological conditions, interpretation of diverse data sets is imperative. In this study, Meteorological Terminal Aviation Routine Weather Reports (METARs) from aerodromes surrounding the Salado Creek watershed of the Edwards Balcones Fault Zone aquifer were analyzed to determine storm timing and source type for each measured precipitation event gathered from the National Centers for Environmental Information (NCEI) Record of Climatological Observations Stations within the area of interest. Storm identities from each of these precipitation events, alongside rainfall quantity estimations from Weather Surveillance Radar-1988 Doppler (WSR-88D) data published by the National Weather Service (NWS) Next Generation Weather Radar (NEXRAD) program, were compared against USGS stream gauge data and groundwater levels to better understand the relationship between the magnitude of precipitation events resulting in hydrological response. Preliminary results indicate a clear seasonality for storm type occurrence. Information gained through the utilization of differing data sets provides insight into which storm types result in aquifer recharge as well as the time of year when most recharge occurs.
