“…Since the sixties and seventies of the 20th century, numerical simulation has gradually penetrated into hydrogeology and becomes an important method for quantitative evaluation and prediction of groundwater quality and quantity [15][16][17]. This study simulates and analyzes the changes of local groundwater environment caused by groundwater recharge from the South-to-North Water Diversion Project.…”

The purpose of this study was to discuss the change in groundwater level and quantity supplemented to Mihuaishun area from South to North Water Division Project. In this study, the method of numerical simulation was adopted to predict and analysis of the trend of groundwater level in the study area within 20 years. The survey concluded that the cumulative loss of groundwater resources in Mihuaishun area in 2007 ~ 2016 reaches -1.784 × 10 9 m 3 . According to the forecast, after the water source of South-to-North Water Division continues to recharge the aquifers at the rate of 0.12 billion m 3 /a for ten years, the local groundwater equilibrium changes from negative to positive, and the water level in the central funnel area increases by 25m. In addition, the artificial recharge of multiple water sources is also related to local hydrology geological conditions. The impacts of the obtained results are analyzing comprehensively the influence of South to North Water Division supplement on groundwater and providing reference for underground regulation and unified regulation of water resources after the water source of South-to-North Water Division transferred into Beijing.

In several unconfined aquifers under irrigated agricultural areas, the groundwater system consists of a saturated porous medium containing miscible fluids (fresh groundwater and saline groundwater). The native groundwater is deep and saline because of the marine origin of the hydrogeologic formation. However, fresh groundwater lenses from deep percolation of the extensive water conveyance and distribution system, as well as from irrigation and rainfall, overlie this native saline groundwater. The thickness of these fresh groundwater lenses varies from a few meters to more than 100 meters. Farmers are using this skimmed groundwater to fill the gap between the supply and demand of surface water in the conjunctive water use environment of the Indus Basin of Pakistan.

A survey was conducted in the Chaj Doab (the area between the rivers Chenab and Jhelum) to characterize the skimming wells used to extract freshwater layer. The survey revealed a drastic increase in the number of skimming wells installed during the drought period from 2000 to 2002. About 36% of skimming wells were found to pump water of EC greater than 2.0 dS/m. The number of strainers varied from 2 to 20 and the size varied from 5 to15 cm. The prevailing depth to the water table in the area ranged from 2 to 10 m, whereas the strainers of the wells were usually at 18 m depth. The spatial and temporal variability of groundwater quality was very high. Based on pumping test results and analysis, it is suggested that skimming wells of about 28 lps discharge should not be installed within a radius of 350 m. Six strainers of 7.5 cm diameter are recommended for installation within a depth of 20 m to pump about 28 lps of water. The skimming wells may be operated continuously for 4 to 12 hours/day, depending on the source of recharge, without having adverse effect on groundwater and pumped water quality.
