Side slope of channel
WebExample12.1: Compute the mean velocity and discharge for a depth of flow of 0.30 m from a lined trapezoidal channel of 0.6 m wide and side slope of 1.5 horizontal : 1 vertical. The Manning’s roughness (n) is 0.012 and the bed slope is 0.0003. Solution: Area of cross section (a) = by + zy2. = 0.60 x 0.30 + 1.5 (0.30)2. WebIn open channel, z is side slope of trapezoidal and triangular channels, defined as horizontal to vertical ratio. Both sides of the open channel are assumed to have the same side slope. Open Channel Equations (note that R=A/P): The non-circular open channel geometry calculation does not check for unreasonable inputs. Please enter positive values.
