The whole Wuyuer River runs from east to west, from its source to Yi 'an gentle slope, with a valley width of about 2km and a river gradient of1.65,438+0 ‰. The maximum water surface width 140- 180m, the maximum water depth 4.6-5.5m, and the maximum discharge of middle and high water level 1.2- 1.7m per second. At low water level, the maximum water surface width is 8m, the maximum water depth is 0.5m, and the maximum flow rate is 0.5ms..
The river enters the vast plain area below Yi 'an, with a valley width of 10 km. The maximum water surface width of Yi 'an Hydrological Station is 680-4000m, the maximum water depth is 2.4-3.8m, and the maximum discharge of middle and high water level is 1.5- 1.7m per second. In dry season, the maximum water surface width 1 1m, the maximum water depth is 0.4m, and the maximum discharge is 0.4ms.. Tail River downstream of Wuyuer River (north of Binzhou Railway) is a vast Tang Wei with nine channels, no obvious rivers, scattered with lakes, and the terrain is low and flat, with a gradient of 0.04‰. The water flow can't be observed by naked eyes, and the water from the upstream can't flow out of this area that year.
South of Binzhou Railway is mostly a closed-flow lake bubble area. From the late 1950s to the early 1980s, the South-to-North Water Diversion Project and the Lianhuan Lake Water Supplement Project were successively built, and a 64.9-kilometer-long water conveyance trunk canal from Fuhai to Lianhuan Lake in Fuyu County was excavated, and a 60-kilometer-long reed canal was opened, which made the incoming water from the north of Binzhou Railway flow into Lianhuan Lake slightly faster than the natural conditions, and could not be discharged into Nenjiang River through the Lianhuan Lake Control Project at high water level.
