Abstract
The South-to-North Water Transfer Project plays an important role in guaranteeing the sustainable development of economy and society in North China. The first phase of the middle route of the South-to- North Water Transfer Project (m-SNWTP) has been running safely in the past three years, and the dispatched water amount is increasing. This paper mainly describes the water operation of the m-SNWTP and the groundwater protection in the water-receiving areas. Up to the end of June 2018, more than 1.4×1010m3water had been supplied to the m-SNWTP benefited regions, including 8.65×108m3environmental water. In addition, the m-SNWTP provides water source guarantee for the environment restoration. Over 1.326 ×109m3overexploited groundwater has been reduced in the urban areas of the water-receiving areas, and the continuous decline of groundwater level has been effectively curbed.
Highlights
China is a country short of water resources
The Yangtze River is the largest river in China with an average annual runoff of about 960 billion cubic meters.94 % of water from the Yangtze River flows into East China Sea, so it is possible to divert some water from the Yangtze River basin to alleviate the water shortage in North China
This paper mainly describes the water dispatching situation since the operation of the middle route of the South-to-North Water Transfer Project (m-South-toNorth Water Transfer Project (SNWTP)) and the groundwater protection in the corresponding water-receiving areas (WRA)
Summary
The total amount of water resources reaches about 2800 billion cubic meters, water resources per capita is only 1/4 of the world average due to the large population in China. According to the studies on this issue for several decades, the South-toNorth Water Transfer Project (SNWTP) that diverts water from the Yangtze River to the North China is proposed [2]. The Yangtze River is the largest river in China with an average annual runoff of about 960 billion cubic meters.94 % of water from the Yangtze River flows into East China Sea, so it is possible to divert some water from the Yangtze River basin to alleviate the water shortage in North China.
