Area of Science:

  • Hydrology
  • Hydrogeology
  • Water Resource Management

Background:

  • Land use changes significantly affect water resources, particularly groundwater recharge and stream discharge.
  • Predicting these impacts requires understanding groundwater response times, especially in large catchments.
  • Data scarcity in large catchments limits the application of detailed numerical models.

Purpose of the Study:

  • To develop a simple analytical model for estimating groundwater response times in sloping aquifer systems.
  • To provide a method for incorporating groundwater variability into catchment hydrological models with minimal overhead.
  • To inform water resource planning in large, data-scarce catchments by predicting groundwater discharge based on broad catchment characteristics.

Main Methods:

Related Experiment Videos

  • Developed an analytical model to simulate features of real, sloping aquifer systems.
  • Derived a groundwater response timescale from the analytical model.
  • Compared model results with published field and numerical model data.

    • Main Results:

    • The analytical model successfully captures key features of sloping aquifer systems.
    • The derived response timescale can parameterize a groundwater discharge function.
    • Model results show good agreement with existing field and numerical data.

    Conclusions:

    • The developed analytical model offers a practical approach for estimating groundwater response times.
    • This method is suitable for water resource planning in data-limited large catchments.
    • The approach has broad applicability for predicting hydrological impacts of land-use change.
