Abstract
As an essential component for the development of the Xiong’an New Area, China’s second capital, groundwater in the area has been overexploited, resulting in ecological and environmental geological problems. Therefore, artificial groundwater replenishment measures are urgently required, for which the evaluation of the recharge potential is an important prerequisite. In this study, a GIS (Geographic Information System)-based multi-criteria evaluation system was constructed, considering the source water conditions, recharge infiltration conditions, aquifer storage conditions, and environmental conditions. In addition, factors such as the distance to a canal, source water quality, slope, vadose zone infiltration rate, drainage density, groundwater depth, aquifer hydraulic conductivity, aquifer thickness, groundwater quality, soil quality, and distance to sensitive areas were also analyzed. GIS was used to draw and calculate potential artificial recharge sites. The results showed that the potential recharge sites in the study area are mainly distributed in the alluvial plains on both sides of the river, with a total area of 2103.9 km2, accounting for 15.8% of the total study area. In the Xiong’an New Area, the potential sites are mainly distributed in the alluvial–proluvial plains on both sides of the Baigou River in the north-central area, with a total area of 39.4 km2, accounting for approximately 2.2% of the total area of the Xiong’an New Area.
Highlights
Groundwater is an extremely valuable and highly important resource with multiple uses [1]
Very good areas for artificial recharge are distributed on both sides of the river channel (Figure 4a)
11 indicators reflecting source water conditions, recharge infiltration conditions, aquifer storage conditions, and environmental conditions were selected in order to identify potential sites for artificial groundwater recharge using a Geographic Information System (GIS)-based multi-criteria method
Summary
Groundwater is an extremely valuable and highly important resource with multiple uses [1]. Owing to its wide global demand [2], groundwater has been overexploited in many areas around the world, leading to ecological and environmental problems. Groundwater recharge is an important factor for sustainable groundwater management. The recharge of natural and artificial aquifers has gradually become a potential mechanism for managing groundwater resources [3,4]. The ecological and environmental problems associated with the overexploitation of groundwater can be overcome using artificial groundwater recharge technology [5,6,7]. An important prerequisite for artificial groundwater recharge is the evaluation of recharge potential, in which the suitability of sites for groundwater artificial recharge is assessed. The evaluation results are closely related to the effectiveness of the artificial recharge
