| Abstract: | Through the layout comparison of three types of cross section, the arc - bed trapezoidal canal cross section (the cell in the second row,second coulum,Table 1 has been decided to be adopted in Jiamakou irrigation district, Yuncheng, shanxi. The adopted type mentioned above has certain evident advantages over the other two types of the cross section, such as better in flow velocity distribution , larger in sediment - carrying capacity, less in volume of earthwork and shorter in construction period, and inverted arch action more or less. In this paper, the comparison Yellow River to irrigate, the lift irrigation area is about 2600 hectare (about 400000mu) . |
