Groundwater recharge is the process by which water from precipitation or surface water sources infiltrates into the ground and replenishes underground aquifers. This natural process is essential for maintaining groundwater levels and ensuring a sustainable supply of drinking water, irrigation water, and other uses. Understanding groundwater recharge is important for managing water resources, mitigating droughts, and protecting the environment. Researchers in this area study the factors that influence recharge rates, such as soil type, land use, climate, and hydrogeology, and develop strategies to enhance recharge and maintain water quality.
