To solve a few problems such as great depth and large amount of earthworks occurring when a parabolic cross-section is applied in large-and medium-sized channels,a channel with compound cross-section was proposed,which was subject to a flat bottom and two 2 th-order parabolic side walls.Analytical formulas for determining the channel cross-sectional area and wetted perimeter were deduced.Based on the open-channel uniform flow theory,a relationship between flow and water depth was established for the channel...
