What is the primary difference between a recharge wetland and a discharge wetland?

The primary difference between a recharge wetland and a discharge wetland lies in their water dynamics, particularly regarding how they gain and lose water. Recharge wetlands are characterized by gaining water, predominantly through surface flow, which contributes to the replenishment of groundwater aquifers. This means these wetlands act as areas where water gathers and infiltrates into the soil, ultimately increasing the water table in the surrounding areas.

In contrast, discharge wetlands are locations where groundwater emerges at the surface and typically results in water being lost to the atmosphere through evaporation or to other aquatic systems. They often function as natural outlets for groundwater, releasing water into streams or other bodies of water.

By understanding that recharge wetlands primarily gain water through surface flow, we can infer their ecological role in maintaining local hydrology and supporting water availability in surrounding ecosystems.
