Numerical modeling the impacts of increasing groundwater pumping upon discharge decline of the BL Spring located in Xilin Gol League in east inner Mongolia, China

Frontiers in Environmental Science, Journal Year: 2024, Volume and Issue: 12

Published: Aug. 30, 2024

Spring discharge decline induced by increasing groundwater pumping under the background of water demand for agricultural, industrial, and domestic utilizations has been recognized as a significant geo-environmental issue which poses great threat to springshed eco-environmental safety. In this study, numerical approach was utilized series 3D flow models based on MODFLOW module were developed simulate current-stage future trends spring discharges impacts due rapid development tourism in BL located Xilin Gol League east Inner Mongolia (China), purpose understanding responses various scenarios future. Simulation results indicated that: (1) reduced from 201.4 m 3 /d 193.7 (reduction ratio 3.80%) scheme; (2) spring-discharge-affected zone is 2.025 km 2 scheme within contributes decline; (3) impact well nearest most while farthest negligible; (4) would reduce 25%, 50%, 75%, 100% if total rate seven abstraction wells increase 45.8 (current-stage scheme) 297.7, 586.2, 888.5, 1,176 /d, respectively. The outcome study can provide useful references advising sustainable exploitation strategies meet requirement supply premise management protection.

Strategies for Sustainable Water Management

ARO-The Scientific Journal of Koya University, Journal Year: 2024, Volume and Issue: 12(2), P. 107 - 118

Published: Sept. 5, 2024

Groundwater in the Rania basin, Iraqi Kurdistan region, has been under intensive exploitation last two decades, where quantity and quality are both affected. Hence, any attempt to protect aquifers become an urgent need. Saruchawa, Qulai Rania, Kanimaran three large springs, among dozens of others area, that heavily relied on as sole or main source water supply. Hydrochemical analysis, first most practical step evaluating quality, was carried out through 60 samples collected from 13 springs 17 wells dry wet seasons (October 2018 May 2019). Laboratory results show a high calcium bicarbonate concentration with weak acids’ dominance. Protection zones delineated for these using aquifer susceptibility contamination analysis recession part spring curves. The equivalent relationship between protection factor (Fp) produced by Epikarst, protective cover, infiltration condition, Karst network development mapping method groundwater zone (S) is considered. Springs mapped be S2 (a highly vulnerable area), whereas Saruchawa Spring located S1 (very vulnerable). Based second (recession curve analyses), all selected fall (D-type) vulnerability category. As result, immediate going surrounded inner zone, enclosed within outer which covers remainder catchment area.

Effect of Faults and Fractures on Springwater Quality and Discharge of West Phaileng, Mizoram

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: May 3, 2024

The North Eastern part of India compromises hilly slopes and ridges. main source water is river, streams, rainfall springs. Due to change in environmental variables, many springs streams are drying up as discharge decreases. A lithological study shows the area consist clay, silt, shale, siltstone sandstone where porosity low leading yielding capacity. Hydrogeological geochemical composition studied represents within this region immature major ions Na⁺>Mg²⁺>Ca²⁺>Mn²⁺>Fe²⁺>K⁺ cations anoins HCO₃^->Cl^->SO₄^2->NO₃^->PO₄^3-. mineral saturation indices constructed using PHREEQC showed supersaturation with dolomite, siderite vivianite. hydrogeochemical formation mechanism Gibbs Diagram Piper diagram suggested rock weathering type. Principal Component Analysis (PCA) was performed a multivariate analysis determine correlation between different components hydrogeochemistry. assessment springwater quality index (WQI) good for most samples. conceptual recharge model anticipating mountain front spring water. hydrograph modelled Maillets. It observed that two types flow, firstly initial larget slope corresponding conduit flow secondly smaller diffuse system. Thus regions West Phaileng attributed which influenced by faults fractures.
