Document Summary
The flow area can be divided into 3 regions by the normal depth line (ndl), the critical depth line (cdl), and channel bottom. If y0 > yc the slope is "mild" (m) and m1, m2 or m3 profiles occur. 1- calculate y0 from chezy-manning eq. and sketch on each channel reach. 2- calculate yc from q2b/(ga3)=1 or for a rectangular channel from yc = (q2/g)1/3 and sketch on each reach. Note that yc does not change with so. 3- identify very long channel reaches where uniform flow is expected (y y0). 4- mark the location of controls and critical points (where y or yc are known, respectively) from rvf calculations. Locations of critical points (y=yc: over hump where h=hc, change of slope from mild to steep (fr < 1 to fr > 1). (y>yc just upstream of the slope break and y
