Identifying Potential Sites for Artificial Recharge in the Plain Area of the Daqing River Catchment Using GIS-Based Multi-Criteria Analysis

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.

Comparative assessment of groundwater recharge estimation using physical-based models and empirical methods in Upper Greater Mae Klong Irrigation Project, Thailand

“…For example, the assessment of groundwater potential in the Thachin and Mae Klong River Basins was studied in 2008; the recharge rates were estimated and classified according to the specific crops and land use types in the area (Department of Groundwater Resources, 2008). In addition, the potential sites of groundwater recharge in arid and semiarid regions in Asia have been assessed in numerous studies by applying geospatial and multi-criteria decision analysis technologies (Kadam et al, 2020;Kaewdum and Chotpantarat, 2021;Xu et al, 2021). The potential of utilizing groundwater resources in transboundary aquifers has received much attention for the sustainable development of groundwater systems (Liu et al, 2020;United Nations Educational Scientific and Cultural Organization, 2006).…”

Water Recharges Suitability in Kabul Aquifer System within the Upper Indus Basin

“…GIS is able to effectively handle complicated spatial-temporal data and various datasets for the same geographical location [31]. Several researchers have used RS and GIS approaches for delineating potential sites and identifying artificial groundwater recharge areas [32][33][34][35][36][37]. Other methods are based on bivariate and multivariate statistical analysis with decision making in prioritization of the collected information [38,39].…”

Identification of the Dominant Factors in Groundwater Recharge Process, Using Multivariate Statistical Approaches in a Semi-Arid Region

“…Groundwater recharge is an essential part of the hydrological cycle and an essential factor for the sustainable management of hydric resources [1][2][3][4]. Recharge feeds aquifers and is essential to balance the demand and supply of water to develop activities, particularly in arid and semi-arid regions [5][6][7].…”
