Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a … Visa mer Diffused or focused mechanisms Groundwater recharge can occur through diffuse or focused mechanisms. Diffuse recharge occurs when precipitation infiltrates through the soil to the water table, and is by … Visa mer Rates of groundwater recharge are difficult to quantify. This is because other related processes, such as evaporation, transpiration Visa mer • Drainage • Impervious surfaces • Soil compaction • Groundwater pollution Visa mer Climate change Urbanization Further implications of groundwater recharge are a consequence of urbanization. Research shows that the recharge rate can be up to ten times higher in urban areas … Visa mer • Water portal • Aquifer storage and recovery • Contour trenching • Depression focused recharge • Dry well Visa mer WebbRecharge areas are at higher elevations, where the water has high gravitational energy. It was energy from the sun that evaporated the water into the atmosphere and lifted it up to the recharge area. The water loses this gravitational energy as it flows from the recharge area to the discharge area.
