Groundwater is one of the important sources of potable water. The water table fluctuation method was used to evaluate the annual variations in water level rise and to estimate the groundwater recharge during pre interventions and post interventions phase of Domagor-Pahuj watershed development. The area experiences an average annual rainfall is 880 mm. The estimates of average annual water table fluctuation and change in groundwater storage volume of randomly selected thirty wells of pre-interventions and post-interventions phases of watershed were 3.03 to 4.34 million m3, and 1.52 to 2.18 million m3, respectively. The total annual groundwater recharge potential estimated for the areas was 1.47 million m3 before intervention and 2.06 million m3 after intervention.

Abstract


Groundwater is one of the important sources of potable water. The water table fluctuation method was used to evaluate the annual variations in water level rise and to estimate the groundwater recharge during pre interventions and post interventions phase of Domagor-Pahuj watershed development. The area experiences an average annual rainfall is 880 mm. The estimates of average annual water table fluctuation and change in groundwater storage volume of randomly selected thirty wells of pre-interventions and post-interventions phases of watershed were 3.03 to 4.34 million m3, and 1.52 to 2.18 million m3, respectively. The total annual groundwater recharge potential estimated for the areas was 1.47 million m3 before intervention and 2.06 million m3 after intervention.
