Recharging of groundwater takes place by the rainwater and water present in the water source like river and ponds. The water tends to seep through the soil and fill the empty spaces and cracks below the ground. That’s how groundwater gets recharged.
The groundwater gets recharged through the process of infiltration. Infiltration means the seeping of water from rivers and lakes into the empty spaces and cracks deep below the ground. The rainwater and water from other sources such as rivers and ponds seeps through the soil and fills the empty spaces and cracks deep below the ground. The process of seeping water into the ground is called infiltration.
- The greatest factor controlling infiltration is the amount and characteristics (intensity, duration, etc.) of precipitation that falls as rain or snow.
- Some soils, such as clays, absorb less water at a slower rate than sandy soils. Soils absorbing less water result in more runoff overland into streams.
