Q$3)$ A unit hydrograph is to be developed for a $120-m{i}^2$ watershed. $10$ mi $,$ Average slope is $80\frac{f}{m}i)$

a$)$ Find the peak flow $($in efs$)$ if the Snyder's method is used.

$120m{t}^2$ watershed

$Ct=1\mathrm{.}8$

$CP=-6$

$L=15mi$

$LC=10mi$

Avg slope $=80\frac{H}{m}i$

$t_P=c+(ccc{)}^3$

$=1\mathrm{.}8(1510{)}^{\mathrm{.}3}$

$=8\mathrm{.}09$

$9_P=640cP\frac{A}{1P}$

$=640\mathrm{.}6\frac{80}{8.c9}$

$=5695\mathrm{.}9Cs$

b$)$ If the duration of this unit hydrograph is $2$ hr $,$ find the time to rise and the time base of the hydrograph.
