Study on water level correlation of key nodes in the north line of East Zhejiang Water Diversion Project

Eastern Zhejiang is an important area for the economic development of Province. However, water resources in eastern are relatively poor. After completion north line East Water Diversion Project, catchment and drainage connecting rivers all counties cities have been dredged, flood control capacity has improved, river channels along also comprehensively renovated, network environment Shangyu City, Yuyao City Cixi diversion significantly environmental quality around Hangzhou Bay on South Bank Qiantang River improved. In order to find out correlation between levels key nodes project provide more targeted guidance future scheduling, this paper uses partial least square method calculate relationship each node. It found that there a significant upper level Sanxing sluice under Xinsan Mashan sluice, certain with xinsanjiang sluice. The upstream Xiaoshan hydroproject Heshan obvious; There most linear Hengjiang xisantang Lingshan, Qitang, Sitou Sitou. Yangxun bridge, Puqian gate Qitang significant, other stations addition, great bridge downstream level. Attention should be paid observing during dispatching process.
