WebThe depth of a trapezoidal channel section is 2m, base width of 3m and has a side slope of 1H:2V. Calculate n if the bed slope is 1 in 1000. Calculate the velocity of flow through a channel having depth of 1.2m and specific energy equal to 1.24m. WebOct 7, 2024 · The uniform flow approximation for boundary stress—the so-called depth-slope product, τ bf = ρgH bf S—can only be applied over length scales significantly larger than individual bends. As pointed out by Dietrich et al. , it is the lowest-order stress model. Higher-order behaviors like flow around bends produce stresses that vary spatially ...
