WebMar 14, 2024 · 1. According to TR-55, here, you use total rainfall. This requires a bit more information about the watershed, namely the time of concentration (which affects the unit peak discharge). Then, from TR-55: q p = q u A m Q F p where: q p = peak discharge (cfs) q u = unit peak discharge (csm/in) A m = drainage area (mi 2) Q = runoff (in) F p = pond ... WebMar 19, 2024 · Moreover, peak runoff and snow melt are closely related in snow-dominated basins; thus, a temporal shift in the time to peak reflects the impact of climate change . At the end of the century, future melt runoff is expected to peak one month earlier in April rather than May (with 20–25-day shift), as it did in the reference period ( Figure 5 ...
WebA 60-ac urban watershed (time of concentration tc = 15 min) in Norfolk, VA has a SCS curve number CN = 85 and 10% of the area is ponded. If the 50-year, 24-hr rain is 8 in, find the 50- year peak discharge. The answer is 205 cfs. Just need the procedure to get that value. This problem has been solved!
