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 flux to the water table surface.

The goal of establishing critical aquifer recharge areas (CARA) is to protect a community’s drinking water by preventing pollution and maintaining supply. We help cities and counties comply with CARA requirements that are required by the state Growth Management Act.

Aquifer storage and recovery (ASR) and managed aquifer recharge (MAR) increase groundwater levels by supplementally recharging groundwater. ASR and MAR can help increase the availability of water during the summer by capturing and storing water during cooler months, when streamflows are high and water demands are low.

2024年10月23日 · Aquifer recharge (AR) and aquifer storage and recovery (ASR) are manmade processes or natural processes enhanced by humans that convey water underground. The processes replenish ground water stored in aquifers for beneficial purposes.

Precipitation is responsible for filling our streams and lakes and allows for infiltration of water to recharge our aquifers. Heatwaves and droughts have become more common in the last 50 years. With heatwaves, groundwater resources will be in …

Groundwater levels are declining across the country as our withdrawals exceed the rate of aquifers to naturally replenish themselves, called recharge. One method of controlling declining water levels is by using artificial groundwater recharge.

Aquifer recharge is water that moves from the land surface or unsaturated zone into the saturated zone. Quantitative estimation of recharge rate contributes to the understanding of large-scale hydrologic processes.

Defined as water that moves from the land surface or unsat-urated zone into the saturated zone, aquifer recharge is vitally important for understanding the hydrologic cycle as well as for applications to water-resource manage-ment.

2024年12月20日 · Enhanced Aquifer Recharge (EAR), often interchangeably referred to as Managed Aquifer Recharge (MAR), has tremendous potential as a process to augment water supplies, replenish groundwater, and restore streamflow in the face of increasing populations, urban development, and climate change.
