Answer:
Infiltration is the process by which water enters into the ground. There are three main processes involved in infiltration:
Intake: This is the initial stage of infiltration where water is first absorbed by the surface soil layer. The surface layer acts like a sponge and absorbs water until it becomes saturated.
Transmission: Once the surface layer becomes saturated, the water begins to move downward through the soil. The water moves through the spaces between the soil particles and through the interconnected pores and fissures.
Percolation: This is the final stage of infiltration where the water continues to move downward until it reaches the groundwater table. The rate of percolation depends on the soil properties, such as the size and distribution of pores, soil texture, and structure.
So, these three processes, Intake, Transmission, and Percolation, work together to allow water to infiltrate into the ground.
