Expert Solution
Step 1: Mention the given data.

Drainage area (A) = 60 mi squared

basin coefficient (BC) = 1.35

storage coefficient (SC)  = 0.6

overland slope (Y) = 0.05

curve number (CN)  = 82

longest flow path (L) = 10 mi

 length of the flow path from outlet to centroid = 3.2 mi

To find:

a) Time to Peak (t subscript p right parenthesis

b) Time to Reach the Rising Limb Peak (t subscript r)

c) Time of Recession left parenthesis t subscript R right parenthesis

d) Time to Peak of the Rising Limb left parenthesis t subscript P R end subscript right parenthesis

e) Total Runoff Volume left parenthesis t subscript p right parenthesis

f) Peak Discharge left parenthesis Q subscript p right parenthesis

g) Width of the Hydrograph at 50% peak flow left parenthesis W subscript 50 right parenthesis
