WebThe flow depth is the distance between the channel bottom and the water surface. For rectangular chan-nels, the depth is the same across an entire cross sec-tion, but it obviously varies in natural channels. Depth is often measured relative to the channel thalweg (or lowest point). Normal depth is the depth of flow in a WebThis expression for Froude number applies to any single section channel. For rectangular channels the hydraulic depth is equal to the flow depth. ... When flow is at critical depth, equation 7.4 must be satisfied, no matter what the shape of the channel. • Subcritical Flow - Depths greater than critical occur in subcritical flow and the ...
WebJul 23, 2011 · Substituting V c = Q/A c = Q/by c and q = Q/b (where b = the width of the rectangular channel), and solving for y c gives the following equation for critical depth: y c = (q 2 /g) 1/3. Thus, the critical depth can be calculated for a specified flow rate and rectangular channel width.
