Hangbu River

Hangbu river was called Longshu River and Nanxi River in ancient times, and Qianhe River and Bayang River in Qing Dynasty. In 1949, the people's Government of Shucheng County named it Hangbu River, which has been used up to now. The upper source of Hangbu river is Xiaotian river. It flows from the east foot of maoerjian (1415 meters above sea level) in Dabie Mountain Area of Yuexi county to the northeast. It flows through Baiguo River and Yaohe River to Longjing river of Zuona in nanyuefan. It flows eastward to Xiaotian Town, right to Shuanghe River and Yellow River. It flows northward to Dahekou, left to Jiumu river. In the reservoir area, the water comes from the tributaries of Zuona talc River and younawusha river. Zhongmei town was an important business town in the mountainous area. It was known as Tianzhen town on rafts and sent to Sanhe Town by boat to Chaohu Lake. After the Longhekou reservoir was built in 1958, it was submerged and moved to the bottom of the reservoir. It was rebuilt downstream of the reservoir dam. Now it is renamed as Longhekou town.

Hangbu River

Hangbu river is an important tributary of Chaohu in Yangtze River system. It was called Longshu River and Nanxi River in ancient times, and Qianhe River and Bayang River in Qing Dynasty. In 1949, the people's Government of Shucheng County named it Hangbu river. The upper source of Hangbu river is Xiaotian River, which flows from the east foot of maoerjian (1415 meters above sea level) in Dabie Mountain Area of Yuexi County. It flows through Yuexi and Shucheng counties in Lu'an City, Lujiang and Feixi counties in Hefei City, and flows into Chaohu in Sanhe Town. The total length is 145 km and the drainage area is 3064 square km. There are famous hangbuhe irrigation area and Longhekou reservoir in the basin. It has better irrigation and shipping benefits.

General situation of main stream

River course

Hangbu River, known as Longshu River in ancient times, is also called Nanxi because it is in the southeast of Shucheng County, Anhui Province. It is also called Qianhe in Shucheng county annals by Guangxu of Qing Dynasty. In 1949, it was renamed Hangbu River as an important downstream market town.

Ancient books and records are said to have originated from Jingyuan (gujingyuan) in Yuexi County, but actually from maoerjian in Shiguan on the west side of Tongan village in Yuexi County. The Northeast flows through the Longjing River in the west of the main source of the book, and then flows to the Yaoxi River and Naxi River in the north. It flows northward into Chawan of Shucheng county and joins the chashui River from fengxiang'ao in Yuexi County. From the east to Xiaotian Town, Shuanghe river flows from the south to the north, Shizao River and Jiumu river flow from the west to the north, Xiaohekou River and youhuishan Qili river flow from the east to the northeast, and enter Longhekou reservoir at gravel beach. This section is called Xiaotian river. In the reservoir area, there are Huashui River and Hepeng River (Wusha River). The reservoir flows through jiujingsi in the northeast, Jiujing River in the right bank, Zhedong Longtan River in the right bank, dike in the left bank, qimenyan, Xinjie and gancha River in the northeast, majiahekou in the northeast, Baimalong in the right bank, Nangang River in the right bank, zhucaogou in HeXinglong in the left bank, Qingshui River in zhougongdu in the East, jiangjunlong in the north, qiandashan in the East After passing through Hangbu, they enter Guanghan and wangliudu in Lujiang County, turn north to Sanhe Town in Feixi County of Hefei City, join fengle River, flow eastward through datanwan and Beizha, and flow into Chaohu Lake. The total length is 145 km and the drainage area is 3064 square km.

River course changes

Before 1883 (the ninth year of Guangxu), Hangbu River diverted flood from wangsi Liudu, the main stream flowed into Nanhe, xiabaishitian river flowed into Chaohu, and its tributaries flowed into Sanhe Town of Hefei county and confluenced with fengle river. During the flood of the ninth year of Guangxu, fengle river was blocked by floating objects in the West Bridge of Sanhe Town, and the dike was destroyed. A channel was washed out along the downstream polder mouth and entered Houhe, where Xinhe river is located, making the channel straight into Chaohu“ In 1722 of the 61st year of Kangxi, the county magistrate, Jiang Heming, raised the North Township and the people in the township, and reopened the Qianhe river for water transportation. From longwanglong to Xinhekou, the excavation was 70 Li in length, 2-3 Zhang in width and 8-12 feet in depth. It took three months to complete. Since then, the river in the county has been connected by boats. See Shucheng county annals.

Basin hydrology

Hangbu river is located in mountainous area above Longhekou reservoir, with large drop, rocky and pebble bed, 80-200m wide; below Longhekou is Pingfan, with small drop, sandy bed, 120-300m wide; from Wangshi Liudu to Sanhe Town, the original dike distance is less than 100m, and the river bottom width is only 50m. Due to the large area of upstream ponding, the middle and lower reaches of the river bend narrow, flood discharge is not smooth, often flood disaster. During the Wanli period of Ming Dynasty, Kangxi period of Qing Dynasty and Qianlong period of Qing Dynasty, there were three times of road changes. In 1914, the peak discharge of Longhekou reached 6400 m3 / s. After the founding of the people's Republic of China, the Longhekou reservoir was built. In 1969, there was a mountain torrent, and the inflow was as high as 10320 m3 / s. The middle and lower reaches of the river have been renovated for many times, and the flood discharge capacity of the section from jiangjunlong to datanwan reaches 1960 m3 / s, and that below datanwan is 2700 m3 / s.

Main tributaries

Fengle river was called Taoxi in ancient times, Houhe in Qing Dynasty, also known as Jiehe. It has a total length of 117.5 kilometers and a drainage area of 2080 square kilometers. There are three sources, South, North and middle, all of which come out of Lu'an City. Zhangmuqiao River, also known as Xiaojie River, originates from dashanzhai Qiaogang in the south, flows to donghekou in the northeast, converges with the East water from Songliao rock Baoerling, and flows to Jiangjunshan aqueduct to longzui in the East. It originates from the sigutan River in the north, xiaochunshugang in the north, converges with the slop water on the East and south sides of Jianghuai Watershed in jijiandian, Xiaohuashan and Longxue mountains, and flows to Shuanghe town in the East. Zhongyuan Chenjiahe River, also known as Zhangdian River and Mapeng River, originates from zhumajian of fenghuangtai and haozhuling of hengtanggang. It converges at zhangjiadian, passes through Dashan aqueduct, flows eastward to Shuanghe Town, converges with sigutan River, and then flows eastward to longzui and Zhangmuqiao river. At this point, fengle river has three sources. Longzui is the junction point of Lu'an, Shucheng and Feixi counties. In history, there were no dams in the three counties, and the floods flooded down the floodplain. After the founding of the people's Republic of China, embankments were built on both sides of the lower reaches for flood control, forcing the water level to rise, and flood disasters still occurred frequently. After crossing longzui, it flows eastward, then crosses Taoxi bridge to Sanhe Town, where it originally converges with Hangbu River, and then extends eastward to join datanwan and flows into Chaohu Lake.

Yaojiahe River, originating from jielingtou, Shiguan Township, Yuexi County, flows to the northeast and enters Shucheng County under Yaohe river. It's a typical valley river. It is 35 kilometers long. Before the 1950s, people along the river built their own hydraulic drum pestles to process wood flour and grain. It is a tributary of Hangbu river.

The Qianmu river originates from qiwangmiao in the southwest of Huoqiu County, flows through Miaozhuang in Lu'an City to Hekou Jinan, with a length of 35 km, a drainage area of 160 square km and a slope of 0.94 ‰.

Shanqili River, originated from wujishan in the south of Shucheng County, flows through renxingdi to hejialaozhuang, with a length of 20 km, a drainage area of 103 square kilometers and a river slope of 7.3 ‰.

Hepeng River, formerly known as Wusha River, originates from huangtouguan in the southwest mountain area of Shucheng county and the north foot of Huayan West. Through Ansai and Xiaojie, to Hefeng River in Heping Village, to Huiyu River in Shuanghekou in the East, to Helan flushing in zhuhuangdian, to Xinkailing in the north through Hepeng old street, and to Longhekou reservoir. It has a total length of 32.5 kilometers and a drainage area of 200 square kilometers. The river is a seasonal mountain river with large bend, rapid flow, many beaches, 40-180 meters wide and 1322 m3 / s maximum flow. In the 1970s, in xiezishi, Duci, Heping, Erhe, guanjing (well), zhuhuangdian, Yulong, Huanghe and other sections of the Yellow River, we cut and straightened the bends, built embankments and repaired stones, which achieved certain results in the development of grain production. Longtan River originates from dahuijian, Huayan mountain, chongxiang Township, Shucheng County, passes through longmianchong in the East, reaches Wanghe River and Fenglin River in the East, goes through sandaowu to Hufan River and Tangchi River in yaojiahe Township, and enters Hangbu river through guanyinan, Quedian and YeFan village in Dudian Township, with a total length of 31.8 km and a drainage area of 320.9 square kilometers. The river is a seasonal mountain river with large bend, rapid flow, serious scouring on both sides and silting up of the river. The width of the river is 50-250m, and the maximum flow is 1810m3 / s. In order to reduce disasters, in the winter of 1975, chengchong people's commune organized people to dig 600000 cubic meters of earth and rock and build 300 mu of farmland in sandaowuanqiaoling. At the same time, in Wanghe, Tangchi, Hufan, jiangjunling, Dudian, YeFan and other sections, the bend was cut and straightened, the dike and stone were built, the riverbed was reduced, and the local treatment was carried out. Nangang River, commonly known as Kongjia River, originates from Donglong and Xilong in Shucheng county. The two rivers converge at the sand ridge, and then turn north to baimagang to enter Hangbu river. It has a total length of 30 kilometers, a drainage area of 150 square kilometers, a river width of 30-120 meters, and a maximum flow of 790 cubic meters per second. Because the riverbed is silted up, some of them are higher than farmland, so mountain torrents break out and overflow without breaking dikes. Local governance was carried out in the 1970s. Above the sand ridge, we should "stand by the side of the small river", and below the sand ridge aqueduct, we should reach Zhulaozhuang, Nangang Town, so as to achieve "one line for the big river". We should build embankments and stones on both sides of the river to reduce the river bed. However, in the section from xiaoyankou to Hangbu river via Jinxing, the river course is curved and the water delivery is not smooth. In order to expand the water outlet, the relevant departments put forward the treatment scheme of abandoning the bend river from laoheshedi to Baimalong. Due to the land boundary between villages, the contradiction between upstream and downstream drainage and irrigation could not be properly solved and could not be implemented. Qingshui River originates from Fuchong and HongChong in Shucheng county. Erhui river flows from Shanbu. It turns north to Hangbu river through Shucha (gouerkou) town, Longwangmiao town and baishen town. It has a total length of 34 kilometers, a drainage area of 45 square kilometers and a maximum flow of 700 cubic meters per second. The middle reaches are warped, the lower reaches are narrow, and the water delivery is not smooth. In 1967, Shucha people's commune organized the masses to carry out local governance. From xiaohewan to xuejiaxiaodian, the 11 kilometer long river course was cut and straightened, embankments were built along the bank, the riverbed was dug deep, silt was removed and obstacles were removed. 370000 cubic meters of earth and stone were completed, and the new river was 20 meters wide and 5 meters deep.
