Abstract:

Nowadays, there are different methods to estimate groundwater reserve with different points of view, especially for mountain areas. This paper presents a method to estimate groundwater reserve for high mountain and water scarce areas in Northern of Vietnam by calculate groundwater storage and water recharge. Groundwater storage in geological formations is estimated by storage coefficient (μ), thickness (H) and area (F) of aquifers. These values have been defined hydrogeological tests or investigations in situ, experience coefficients. Groundwater recharge is estimated by using module of baseflow which is defined for each hydrogeological formation. Related factors such as lithology, steep of tomography and plant cover were used to estimate infiltration coefficient. The study results show the groundwater reserves of 14 provinces in Northern area is 25.548.887 m3/day and total available groundwater at 96 scarce mountainous communes is 173.557,8 m3/day.
