Design Projects D10.1 A straight weedy-earth channel has the trapezoidal shape 35°. The channel has of Fig. 10.7, with b = 4 m and 0 = a constant bottom slope of 0.001. The flow rate varies seasonally from 5 up to 10 m²/s. It is desired to place a sharp-edged weir across the channel so that the water depth 1 km upstream remains at 2.0 m ± 10 percent throughout the year. Investigate the possibility of accom- plishing this with a full-width weir; if successful, deter- mine the proper weir height Y. If unsuccessful, try other alternatives, such as (a) a full-width broad-crested weir or (b) a weir with side contractions or (c) a V-notch weir. Whatever your final design, cite the seasonal variation of normal depths and critical depths for comparison with the desired year-round depth of 2 m.
