Predicting Edwards Aquifer Recharge Using Potential Evapo-Transpiration (PET) Values

The EAA, with its partners (including Barton Springs Edwards Aquifer Conservation District, Bandera River Authority and Groundwater District, the Nueces River Authority, Cibolo Nature Center, Bat Conservation International), and private landowners, is developing a network of weather stations in our shared region. Since some water loss is due to evapo-transpiration (ET) after precipitation, predicting potential recharge of ET is a valuable tool for managing groundwater resources.

This shared network of weather stations collects climatic and soil moisture data that can be applied to calculate PET values at numerous locations throughout the Edwards Aquifer Recharge Zone and Drainage Area. These data are collected every 15 minutes, and transmitted hourly through a telemetry network, available to the public through this EAA web page. Parameters collected at the PET stations are:

  1. Air Temperature
  2. Relative Humidity
  3. Barometric Pressure
  4. Precipitation
  5. Solar Radiation
  6. Dew Point
  7. Wind Direction
  8. Wind Speed
  9. Soil Moisture

The calculations from these data at each of the weather stations aids in our understanding of how, when, and where the aquifer recharges, and are incorporated into numerical models that are used to support management of the Edwards Aquifer.
