Main tributaries of Xin'an River

The Xin'an River basin is located in the rainy center of Anhui Province, with a normal annual precipitation of 1,752 millimeters, ranking the first in the province, and a sound development of the river system and a high density of the river network, which also ranks the first in the province. Especially the left bank of the river system development and density are better than the right bank. In all levels of tributaries into the Xin'an River, the length of the river in more than 10 kilometers, 57; in 10 kilometers below 586. This shows the great density of its river network.

Rate water, also known as Nangang. Originated in Xiuning County, six shares of the tip, for the FengYuan River; to the DiDian near will be MeixiYuan, with the She River, for the Danyuan River; to the mouth of the stream will be a small source of the River, through the Qimen County Teal Peak, will be LuangXi River; and then into the Xiuning County, will be GratiaXi River; through BingTan, will be HangXi River, TongZiXi; through the JiangTan to the mouth of the upper Xixi will be the Yiyuan River; through ChenXia, will be back to the Xixi River; through the ShouCun, will be WangXi River, through the YuetTan to the Dragon Bay will be YanguangXi; and then through the HongLi to the Yantang village near will be the Then it goes through Hongli to Yantang Village and meets Lanshui into Tunxi District, and then it goes through Sanzhong and Liyang to Yanghu and meets Hengjiang River and injects into Xin'anjiang River.

It is the first big river in Xiuning County. The source to the riverbanks of the upper Xikou, both sides of the mountains are steep, the river bends, the bed of the river bed bedrock is exposed, the curved concave bank beach development, mostly by the sand and pebbles deposited. The riverbed is relatively stable, the general width of the river is 25-35 meters, the river has a large drop, with the construction of small and medium-sized hydropower stations in good condition. Below Shangxikou to Chenxia River section, the terrain gradually open, the river width of 60 to 100 meters. Chenxia to the first village area, the river into the canyon, the mountains are steep, the river twists and turns, since the moon pool below, both sides of the low-slope hills, the terrain is open, the river is smooth, the river width of 120-200 meters, the river floodplain is more developed, the riverbanks for the alluvial deposits, is not stable enough, and the vegetation is poor, there is a certain degree of soil erosion.

Hengjiang River, also known as Jiyangshui, Donggang, Baihexi.
