Estimation of Groundwater Recharge Potential of Domagor-Pahuj Watershed Using Water Table Fluctuation Method.

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 FROM AUTHOR]
