Question:
Considering a 20m wide channel, the bed slope is 0.00075 and the observed flow depth is 3.2m. The channel bed is sandy (ds = 0:008m). Calculate: (a) mean velocity, (b) mean boundary shear stress, (c) shear velocity, (d) Shields parameter and (e) occurrence of bed-load motion. If bed-load motion occurs, calculate: (f) bed-load layer sediment concentration, (g) bed-load layer thickness, (h) average sediment velocity in bed-load layer and (i) bed-load transport rate. (Assume that the equivalent roughness height of the channel bed equals the median grain size. Use the Nielsen simplified model).
