Stage 3: Use the following catchment characteristics and the SCS method to estimate the 100-years design peak-flow for the catchment. Catchment area: obtained from Figure 1 Length of the main channel: 54630 m Elevation at the catchment outlet: 53 m Elevation at the most upstream point of the main channel: 1134 m Average slope in the watershed: 2% Average curve number for the watershed: 70 For your convenience, you may round off the time of concentration to the nearest hour.
