Groundwater Recharge：

Groundwater recharge is the process of replenishing the groundwater stores in an aquifer by adding water from the surface. Recharge occurs through infiltration of precipitation, surface water, and irrigation. It is an important mechanism for replenishing aquifers and sustaining groundwater levels.

Groundwater recharge is an important process for maintaining the balance between water availability and demand. It is also integral to the formulation of water-management strategies and plans, such as water supply and irrigation schemes.

Groundwater recharge occurs naturally when water from a river, lake, or stream percolates or infiltrates through the soil and accumulates in the groundwater system. This process can also be facilitated by humans in various ways, including constructing recharge structures, recharging aquifers artificially, aquifer storage and recovery (ASR), and stormwater recharge.

Recharge structures are basins or other engineered structures that are constructed with permeable material to capture surface runoff and allow it to infiltrate into the groundwater. Artificial recharge works by diverting water into groundwater aquifers using pumps, canals, or infiltration wells. ASR is the process of capturing excess surface water supplies, storing them in aquifers, and recovering them for use during dry periods. Stormwater recharge involves capturing stormwater runoff and recharging it into aquifers for storage.

Groundwater recharge is an essential process for sustainable water management and a key factor in maintaining the health of aquifers. It is important to understand the process so that freshwater resources can be used sustainably and effectively.
