Question

what effect does construction of building and roads have on water perolation through soil ? hence effect would have on the water table ?​

Answer 1

Answer:

CONSTRUCTION OF BUILDING AND ROADS AVOID OR STOP PERCOLATION OF WATER. AS THE BUILDINGS ARE CONSTRUCTED ON THE SOIL, THEY DON'T GET AREA TO ABSORB WATER, WHEN WATER IS NOT ABSORBED THEN THERE IS NO WAY OF PERCOLATION AND DECREASES GROUND WATER LEVEL. HENCE, IN THIS WAY THEY AFFECT WATER TABLE.

Answer 2

Explanation:

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.
