Very little effort has been devoted to analyzing the contributions of National Forests to groundwater resources inthe USA and around the world. In this study, the US Geological Survey’s MERAS (Mississippi Embayment RegionalAquifer Study) model was used in the ModelMuse simulating system to estimate more than a century of subsurfacehydrologic processes, groundwater budgets, and spatial-temporal groundwater level distributions in threeforests in Mississippi, USA. The results showed that groundwater recharge and stream leakage are importantfor groundwater storage in this region. All three forests served as groundwater sinks at times and sources atothers, but the volume changes were relatively small. Groundwater levels declined over the simulation period– 1900 to 2014 – beneath all three forests, especially around the DNF (Delta National Forest) where groundwaterabstraction is relatively intense. Knowledge gained from long-term hydrologic simulations and water budgets isuseful when managing forest land groundwater resources.
