Q$1.$ A complex storm occurred over a basin. Ordinates of the direct runoff hydrograph $($DR$)$

and the total hyetograph of the storm are given below. If the area of the basin is $64\mathrm{.}8km2,$

determine:

a$)$ depth of direct runoff,

b$)-$index,

c$)$ depth of infiltration,

d$)$ UH$2$ by lagging method, $($ solve on table$)$

e$)$ UH$6$ by S$-$curve method $($ solve on table$)$

i $(m\frac{m}{h}r)$
