Question $2$

a$)$ Given a triangular $1-$hrUH with

$T_B=12hr($time base of the UH$)$

$T_R=4hr($time of rise$)$

$QP=200$ cfs $($peak flow$)$

Develop a storm hydrograph for hourly rainfall $($in$)$ of $P=[0\mathrm{.}1,0\mathrm{.}5,1\mathrm{.}2].$

b$)$ Repeat the above problem for hourly rainfall $($in$)$ of $P=[0\mathrm{.}2,1\mathrm{.}0,2\mathrm{.}4].$
