Effects of the South-North Water Diversion Project on the Water Dispatching Pattern and Ecological Environment in the Water Receiving Area: A Case Study of the Fuyang River Basin in Handan, China

Abstract

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.

Effect of Land Use and Drainage System Changes on Urban Flood Spatial Distribution in Handan City: A Case Study

“…Urban flooding management is of great significance for Handan City in the prevention and mitigation of natural disasters. However, only a few researchers have performed studies related to urban stormwater management in Handan [38][39][40][41][42][43].…”

Interbasin water transfer in a changing world: A new conceptual model

“…The documented purposes of schemes can be summarised into six primary groups: irrigation, municipal, industrial , hydropower, environmental and flood control . Of this list, environmental aims are the most diverse category, covering a range of sub-aims such as improvements to water quality, enhancing ecological sustainability and supplementing flows to meet environmental minimum flow requirements (Berkoff, 2003; Fu and Yang, 2019; Lund and Israel, 1995). Other usages are identified in the literature, for example, recreation, but the number of schemes which identify these are small, and they have a low priority when cited, so these have not been included here.…”

A Gateway to Rapid Prediction of Water Quality: A Case Study in China’s South-to-North Water Diversion Project

“…If the pollution is widespread and intense, it may also cause shutdown, and even affect social stability, resulting in a great impact on the economy and society of the downstream area. Since the construction of SNWDP, water delivery safety and water quality protection in the project have been a hot issue, which are addressed in many scientific papers focused on water environmental risk analysis [9][10][11], water security evaluation [12], water quality of reservoir and downstream [13,14], water pollution risk simulation and prediction [15,16] and emergency regulation and treatment of water quality [17,18]. However, there are few studies on the rapid prediction of sudden water pollution accidents in Shandong Section, and the methods, models and instruments used in the above studies need a large amount of basic data, while the operation of the model requires a lot of time [19][20][21].…”
