Genetic types of tectonic lakes

The elevation of Wabu is17m, from Baiyangdian to Qianjiatan, with a length of 52km from north to south and an average width of only 5km. The elevation of the lake bottom is15.8m.. Below Qianjiatan is the tail of the East Huaihe River, with a total length of 15 km and two waterways. One is the old river, with a bottom width of 52-56 meters, a water depth of 3 meters and a flow of 53 cubic meters per second. Second, the new river (195 1 year excavation) has a bottom width of18m, a water depth of 4m and a discharge flow of 78m3 per second. Wabu Lake is one of the flood storage areas in the middle reaches of Huaihe River, which burst at 1954. On July 26, the highest flood storage level reached 25.9 meters (the planned maximum was 22.0 meters), with a total flood storage capacity of 3.8 billion cubic meters and a corresponding water surface area of 856 square kilometers. Baiyangdian flows into Wabu Lake, and the effluent flows into Huaihe River.

Wabu Lake is located on the right bank of Huaihe River. Shouxian, in the middle reaches of East He Fei, is a lake with integrated rivers and lakes. Due to the uneven uplift movement between north and south, the floodplain south of the Yellow River is silted, and the accumulated water in the depression is gradually formed. Wabu Street (now Wabu Town) is on its right, hence its name. The lake spans Shouxian, Changfeng and Huainan, mainly in Shouxian. The lake area starts from Baiyangdian in the south and ends at Qianjiatan in the north, with a length of 52 kilometers and an average width of about 5 kilometers from east to west. Normal water level18.0m, water area156km2, lake bottom elevation15.5m, with a corresponding volume of 220 million cubic meters. Donghefei River is the main water source, and the basin is fan-shaped and belongs to hilly area. It starts from Longxue Mountain in the west and reaches the Jianghuai watershed of Wushan Temple in the northeast in the north. Two streams of incoming water flow into Wabu Lake, one from Feixi Buried Hill and the other from Longxue Mountain in Lu 'an. The two streams meet in Dongpu and enter the plain, and Baiyangdian enters the lake area. There is the Wabu River in the east, also known as the river, that is, the ancient water; There is a steep river in the west. The lake passes through the lower section of Donghe Feihe River in Beiwulimiao, Shouxian County, passes through Donghe Feimen (built in 195 1), flows northward to Zhaotaizi and empties into Huaihe River. The total control area is 4200 square kilometers. In the 195 1 Huaihe River Regulation Project, Wabu Lake is listed as one of the four flood storage areas in the middle reaches of Huaihe River, with a planned flood storage level of 22.0 meters, a total storage capacity of 65,438.029 billion cubic meters and a water area of 386 square kilometers. During the flood of 1954, the highest water level of the dammed lake reached 23.29 meters before the flood discharge, which made it difficult to store flood water. There has been no flood since 1954. East He Fei sluice is used for flood discharge and drainage, and another sluice (built at 1992) is connected with Huaihe River.

Wabu Lake was originally a section of the middle reaches of the East Feihe River, and gradually formed a lake due to siltation of the Huaihe River and the Yellow River. The upper reaches of the East He Fei River are rolling hills, and the middle and lower reaches are gradually flat. As early as 65,438+0,500 years ago, it was recorded in the Notes on Water Classics of the Northern Wei Dynasty that the accumulated water in the East River was a Yanghu Lake. In the 13th year of Tongzhi in Qing Dynasty (65,438+0,874), Shouxian River was rebuilt in Sun Jianai. The foreign ministers of Beifushan, Jiexihu and Sanhu are all in front of the Huaihe River. Jindong River joins the waters in the southeast, flows from east to northwest, and joins the Huaihe River along the foothills. The water conservancy project in Shaobeitang, separated by Wabu Lake for dozens of miles, is also immersed in the Wang Yang when the water rises. Its water belongs to Huai River. "This is the earliest name of Wabu Lake in historical materials. In the 17th year of Guangxu in Qing Dynasty (189 1), Wabu Lake was marked in the whole map of Jiangnan Anhui (the 22nd map), with an area of about 32km2. It can be seen that Wabu Lake was originally only a waterlogged area during the flood, but only after the Huaihe River was flooded, it gradually expanded in the past hundred years and evolved into the present lake. According to the dredging project of 195 1 dongfeihe river, it is concluded that "dongfeihe river runs through the middle of Shouxian county, with a total length of more than 60 kilometers, and its middle reaches are near the west of Wabu town. Open and low-lying, covering an area of about 250 square kilometers. When the flood stops, it becomes a lake, so it is also called Wabu Lake. "1938 After the Yellow River flooded, the East Feihe River was generally silted up for more than two to four meters, and Wabu Lake could not discharge water in winter and spring. The wheat crops in the lakeside fields are flooded every year, and the vast and rich villages have become the hardest hit areas. After the establishment of the Huaihe River Regulation Committee, the dredging of the Dongpei River was included in the first phase of construction, with the aim of discharging lake water in spring and ensuring the wheat harvest of130,000 mu of original lakeside farmland.
