tailieunhanh - Research and assessment of potential groundwater exploitation reserves in coastal areas of Ninh Thuan province

This paper presents the results and assessment of the groundwater exploitation reserves in coastal areas of Ninh Thuan province. The research was based on determining the exploitation reserves of all grid cells with dimensions 500 m × 500 m distributed in fresh-salted water areas of the Holocene (qh) and Pleistocene (qp) aquifers. Each grid was assigned the corrected hydrogeological parameter values (depth, gravity coefficient, hydraulic conductivity, and drawdown level). | Vietnam Journal of Marine Science and Technology 2023 23 2 145 159 Vietnam Academy of Science and Technology Vietnam Journal of Marine Science and Technology journal homepage jmst Research and assessment of potential groundwater exploitation reserves in coastal areas of Ninh Thuan province Tran Thi Thuy Huong1 Trinh Hoai Thu1 Nguyen Van Hoang2 1 Institute of Marine Geology and Geophysics VAST Vietnam 2 Institute of Geological Sciences VAST Vietnam Received 19 July 2022 Accepted 6 October 2022 ABSTRACT This paper presents the results and assessment of the groundwater exploitation reserves in coastal areas of Ninh Thuan province. The research was based on determining the exploitation reserves of all grid cells with dimensions 500 m 500 m distributed in fresh-salted water areas of the Holocene qh and Pleistocene qp aquifers. Each grid was assigned the corrected hydrogeological parameter values depth gravity coefficient hydraulic conductivity and drawdown level . The calculation results show that the total amount of potential exploitation reserves in the entire qh and qp aquifers-distributed areas is 10 6 m3 per day whereas in the freshwater area is 106 m3 per day and the saline water area is 106 m3 per day . These potential exploitation reserves can be used for groundwater exploitation management and planning in Ninh Thuan province.
