can you suggest any two method to let more rain water percolate and reach the water underground?

Dear Student

We often observe that rain percolates through muddy areas like parks, fields, forests etc. and collect floors which do not allow their percolation like cemented grounds, roads etc. So, we should have mud based areas on sides of the cemented and coal tar roads so water do not collect on sides and percolates underground.

The soil which percolates more water should be preferred.
