Hydrogeological conditions in the southern part of Dang valley, mid-western Nepal

Abstract

The Dang valley consists of several patches of confined and unconfined aquifer systems. Drilling data reveals that the northern portion of the study area has more permeable surfaces than the southern and central portions. Annual domestic draft and safe yield were calculated to be 7.43 x106 m3/year and 3.16 x 107 m3/year, respectively. The fact that the safe yield is higher than the annual draft indicates the presence of good groundwater potential in the study area.

Implementing conjunctive management of water resources for irrigation development: A framework applied to the Southern Plain of Western Nepal

“…While groundwater abstraction for domestic use alone is estimated to be 7.43 MCM/year. Sapkota (2003) calculated the safe yield from the groundwater aquifers in the southern portion of Dang valley to be 31.6 MCM/year, indicating stress on the groundwater system. The actual volume of groundwater abstraction would be significantly larger after incorporating abstraction for irrigation.…”
