Water shortage and overexploitation of groundwater (GW) have become the key factors restricting the development of the Xiongan New Area (XNA), the environmental management of Baiyangdian Lake, and the social and economic development of surrounding areas. This study used a numerical GW flow model to quantitatively analyze the changes to the shallow GW level and GW reserves of the plain area of the Daqing River Basin over the next 15 years (2021–2035) under different artificial recharge schemes with the south to north water diversion project (SNWDP) acting as the GW recharge source. The results showed increasing GW storage and GW levels and that the regional GW resources are in a positive equilibrium state. The rates of change of the well irrigation supply scheme and the joint river-well irrigation supply scheme in the XNA will increase by 14.56% and 11.04% by 2035 as compared with the current situation. The well irrigation recharge scheme for the XNA was determined to be the most effective when comparing with the effects of the different artificial recharge schemes on the GW levels and recharge. This study provides a reference for the management and protection of aquifers in other areas suffering serious GW overexploitation.

Inter-basin water transfer projects are widely used in water-stressed areas. North China is facing severe imbalance between water demand and water supply. The South-to-North Water Diversion (SNWD) Project was built to transfer water from the Yangtze River Basin to the Hai River Basin. The Fuyang River Basin in the southern part of the Hai River Basin, passing through the Handan city, was chosen as the study area. To identify the effects of the SNWD Project on the water-receiving area, this paper used the decision support system AQUATOOL to simulate the water-dispatching scheme while using the water from the SNWD Project for domestic need in different level years. The results indicate that the SNWD Project provided 128.32 × 106 m3 of water in a wet year, 109.88 × 106 m3 in a normal year and 135.14 × 106 m3 in a dry year to this area. The added quantity of recycled water is 56.75 × 106 m3, 50.59 × 106 m3 and 57.52 × 106 m3, respectively. The water shortage in normal years was covered by the SNWD Project and the water shortage in dry years was reduced by 62.4%. Local environment was improved because of the SNWD Project, i.e., the SNWD water replaced and reduced the use of groundwater and increased the inflow to the Fuyang River and the Yongnian Wetland by increasing the recycled water. This research has demonstrated the SNWD Project has started to play a key role in securing water use and improving the environment in the water-receiving area since its completion in 2014.

For many years, drought is severe in the basins and the mountain area of Nandong underground river basin. The author analyzes the reasons of the drought from the hydrogeological characteristics of the basin, climate characteristics, groundwater pollution ,and study indicates that the drought causes is that shallow groundwater and surface water has been seriously polluted, and it is extremely difficult to look for underground karst water. Then the author analyse solutions to solve these problems: building underground dam in Moshigou to develop Nandong underground river; rising underground water level elevation up to 1253m,it can intercept about 306 million m3 underground water. In this way, the author predict that the water shortage problem can be solved fundamentally in these three basins.

Abstract Water trading is an effective method for solving regional water shortage problems and addressing the uneven spatiotemporal distribution of water resources. Therefore, taking the Middle Route of China's South-to-North Water Diversion Project (MR-SNWDP) as the research object, we present a study on a feasible water trading scheme in the water-receiving area of Henan Province. First, the tradable water of each calculation unit in the water-receiving area was calculated by analyzing the water-saving potential of different industries. Second, a multi-objective optimization model for trading water between different regions was developed, taking the largest social and economic benefits of the water-receiving area as the objective function. Finally, non-dominated sorting genetic algorithms were used to solve this optimization model, and an optimal scheme for water trading was proposed. The simulated results of the optimal scheme indicate that the total water shortage of the water-receiving areas will decrease by 650.69 million m3, and there will be a surplus of 14.98 million m3 of water, and the gross national product will increase by RMB 130.5 billion at a rate of 5.2%. This demonstrates that the water-receiving areas of Henan Province can effectively alleviate local water shortages by trading water without increasing external water supplies.

Abstract Background: Weishan Lake and its surrounding areas represent an important water conduit and storage reservoirs for the Eastern Route due to the South to North Water Diversion Project. It was listed as a potential endemic area for schistosomiasis by the Ministry of Health Schistosomiasis Advisory Committee. Oncomelania hupensis is the unique intermediate host of Schistosoma japonicum in China. To determine whether Oncomelania hupensis could establish colonies in Weishan Lake once introduced from original habitat, in May 2004, 2000 adult Oncomelania hupensis were transplanted from the original habitat to isolated snail cages in Weishan Lake. Results: From October 2005 to October 2016, Oncomelania hupensis were bred in isolated snail cages in Weishan Lake, and samples of the original habitats were collected. The population was monitored, and the morphology of Oncomelania hupensis was measured. Gonads were sectioned and observed under transmission electron microscopy. Oncomelania hupensis could still continually reproduce its population 12 years after transplantation to Weishan Lake. Comparing the morphology with that of animals from the original habitat, it was found that the snail shell length, shell width and aperture width decreased in 2005, and significant changes were observed in the ultrastructure of sperms (axoneme and the 9+2 the axoneme coarse fibers were absent, and chromatin density decreased in the head of the sperm cells) and oocytes (nucleus swelling, endoplasmic reticulum, pale vesicles and lipidosomes decreased and chromatin was absent) of snails breeding in Weishan Lake.Conclusions: Although abnormal development of the ultrastructure of Oncomelania hupensis reproductive gonad was observed, they still survived for 12 years, which might reflect a survival strategy in which the snail trades a degree of fecundity to survive though harsh winters.
