Repeat Problem 4.25 for reach lengths of 6, 12, and 32 km. What happens to the timing and value of the peak flow? Explain.
In problem 4.25
Using only the inflow hydrograph from Example 4.7 (i.e., no precipitation), use HEC- HMS* (iwww.hec.iisace.army.mil/software/hec-hms/download.html) to route the hydrograph through a channel using the Muskingum-Cunge routing method, The channel has a trapezoidal cross section with a 3:1 side slope (horizontal: vertical), a Manning's roughness (n) of 0.039, and a bottom width of 8 meters.
