Out of this, only about 200 mm naturally recharges the ground water aquifers and the remaining part runs off unharnessed into the ocean. Therefore potential exist to capture part of runoff and to store it underground which will be available for use during dry periods. Providing check structures across the unlined drains can increase the recharge capacity of drains. This book, therefore provides a novel method of recharging the ground water. It...
