Question

Determine the 10-year design peak flow rate of rúnoff at: 50 30 바 20 C 06 mín 10 6.0b 20P A2 4 acres C2 0.8 5 min A2 1 0 0.6 04 0.2 2 7912 16203040501 2 34 611012 tha) (min) Duration

Two areas with the characteristics shown in the figure generate runoff that ultimate reaches point b . all flow rea from A1 enters at point a and all flow area a1 enters the chanel at point b . the intensity -duration frequency curves that were provide by the local responsable agency are herein . the time flow from a to b is 8 min

A1 = 5 acres

c1= 0.6

tc =20 min

a2= 4 acres

c2 =0.8 tc = 5min
