Engineering technology of recharging groundwater in Shijiazhuang with water diverted from the Yangtze River

Abstract：Shijiazhuang is one of the cities suffering severe shortages of water resources in northern China, where a huge cone of depression has formed because of excessive exploitation of groundwater. Shijiazhuang is on the broad beach of the Hutuo River and its hydrogeological conditions allow surface water to directly penetrate into the cone of depression and recharge the groundwater. So, it is practically significant to recharge groundwater in Shijiazhuang the water diverted from the Yangtze River. According to different qualities of water from the Yangtze River, by using the existing appropriate groundwater recharging methods and related water purifying technologies and selecting the Hutuo River watercourse, sand pits on flood land and other favorable sites, the technologies of recharging Shijiazhuang groundwater with water from the Yangtze River are discussed and an appropriate engineering technology scheme is put forward, which is expected to serve the strategic control and management of water resources in Shijiazhuang.
