Modeling groundwater depletion

Hydrology Understanding the full effects of human activities on groundwater resources has been a persistent challenge to hydrologic models. Such models often seek to inform best practices for resource management. One important gap in our understanding is how groundwater depletion affects surface water behavior. Condon and Maxwell simulated the impact of 100 years of groundwater declines across the continental United States. Their integrated model illuminates the nature of connections between groundwater pumping and changes in natural watersheds, including the widespread impacts of pumping on evapotranspiration rates and streamflow.
