Groundwater Recharge Area Based on Hydrochemical and Environmental Isotopes Analysis in the South Bandung Volcanic Area
نویسندگان
چکیده
The determination of recharge areas needs to support the groundwater conservation in southern volcanic Bandung area. This study aims determine area based on environmental isotopes and hydrochemical. A sampling 26 was carried out at springs, dug wells, drilling wells. variation chemistry principally is controlled by a combination ion exchange, silicate weathering, calcite, dolomite dissolution minerals. hydrochemical facies were CaCl, CaMgCl, CaMgHCO3, CaHCO3, NaKHCO3. CaHCO3 describe moderate flows. NaKHCO3 shows mixing shallow deep groundwater. central, proximal, medial zone consists 3 groups. Group I considered water originating from local rainwater infiltration; II infiltration elevation which ranges 980–1230 m asl; III estimated be derived between 750–970 asl, IV are more likely show symptoms evaporation or interaction with surface water. discharge characterized less active circulation, dominant HCO3– TDS value distal zone. Hydrochemical helped identification facies.

gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Identifying Seasonal Groundwater Recharge Using Environmental Stable Isotopes
In this study, the stable isotope values of oxygen and hydrogen were used to identify the seasonal contribution ratios of precipitation to groundwater recharge in the Hualien River basin of eastern Taiwan. The differences and correlations of isotopes in various water bodies were examined to evaluate the groundwater recharge sources for the Hualian River basin and the interrelations between grou...
متن کاملEstimation of Groundwater Recovery by Recharge in the Agricultural Area
The Kumamoto area, Kyushu, Japan has 1,041km in area and about 1milion in population. This area is a greatest area in Japan which depends on groundwater for all of drinking water. Quantity of this local groundwater use is about 200MCM during the year. It is understood that the main recharging area of groundwater exist in the rice field zone which have high infiltrate height ahead of 100mm/ day ...
متن کاملQuantitative Analysis of Groundwater Recharge in an Arid Area, Northwest China
The Mixing Cell Model (MCM) is a useful tool that can be applied to areas with limited hydrogeological data, such as arid areas in northwest China, to transform available groundwater hydrochemical data into quantitative information about an aquifer. In this study, we used the MCM to quantify water circulation in the study area and to analyze information such as the supply source composition and...
