Question

What effect does construction of buildings and roads have on water percolation through the soil? Hence what effect would this have of water table?

Answer 1

Answer:

The construction of buildings and roads are gradually covering the open part of the soil with concretes. As a result the rain water run offs fail to percolate (movement of water) through the soil. Water table is the upper level of an underground surface beneath which rocks and soil are completely emerged under water.
