Rainwater percolates through the soil where does this water collect ? What is the level of this water known as ?
Answers
Rainwater is stored after percolation upon the impermeable rocks. This level of water is known as groundwater level.
The rainwater percolates to the deepest layers of the soil and accumulates to form groundwater. The level of this water is known as the water table.
The rainwater is able to percolate through the soil and it goes down to the reservoir of water in the earth, the groundwater. The rainwater increases the groundwater level as it percolates in the soil. Due to the formation of roads and the accumulation of plastics on the ground, the rainwater is not able to percolate through the soil and leads to flooding. The groundwater is beneficial as it can not be evaporated.
The level at which the groundwater is present below the surface of the earth is known as the water table. The percolation of water down the layers of the soil leads to an increase in the water table of the region.
