Calculation of the exploited flow water in the T2ađg sediments at the well Kien Khe, Hanam

Abstract

Groundwater wells in Triassic sediments of Dong Giao formation in Kien Khe, Hanam include 6 wells in an area of 4km2. To evaluate the ability of sustainable exploitation, meeting the demand of water supply, the scientific calculation is very important and necessary. This layer is rich in water, good quality, meeting large water supply requirements. However, if the regime and volume of exploited water cannot be determined, it may cause degradation, depletion or change of water quality of the reservoir. In order to have a scientific basis for exploitation, we have conducted exploration with many types of work (field surveys, geophysical measurements, exploratory drilling, water absorption experiments, sampling analysis, calculation , synthesis of assessment and design of exploitation). Calculation results show that the exploitation of 6 wells with the flow of 1,500m3/day in the study area is reasonable, safe, meeting the requirements of both volume and quality for water supply and sustainable development.
