$1.$ Given below is stream flow data due to a storm of two hour duration. The area of the drainage basin is $2000$ Acre. Determine the total volume of direct runoff $($in inch$).$ Use the constant discharge method to separate the base flow. Plot the hydrograph $(5$ points$).$

$2.$ Prepare a unit hydrograph for the two$-$hour duration storm for this watershed based on the storm given in question$\backslash$# $1.$ Plot the UH $(5$ points$).$

$3.$ Construct a Unit hydrograph for the Four$-$hour duration from the two$-$hour duration UH you generated above. Plot the $4-$ hour UH $(5$ points$).$

$4.$ Based on NRCS triangular UH for a $360$ acres of watershed with average slope of $\backslash (2\backslash \%\backslash )$ and flow $($channel$)$ length of $\backslash (7114\backslash$mathrm$\{$ft$\}\backslash ).,$ estimate the curve number $\backslash ((\backslash$mathrm$\{$CN$\})\backslash )$ for a watershed. Peak discharge of UH is $\backslash (184\backslash$mathrm$\{$ft$\}^\{3\}/\backslash$mathrm$\{$s$\}\backslash )(5$ points$).$
