$($A$)$ Estimate the peak discharge and time to peak of the storm hydrograph at location $2($Figure $4),$ if the inflow hydrograph at location $1($Figure $4)$ is given in Table $4.$ The channel through which the inflow hydrograph travels has the weighting factor $($x$)=0\mathrm{.}2$ and travel time constant $($K$)$ of $10$ minutes. Skecth the hydrographs at locations $1$ and $2($Figure $4)$ Showing all salient features.

Figure $4.$ Basin Network

Table $4.$ Storm hydrograph at point $1($inflow hydrograph to the channel$)$

$($B$)$

Discuss how will the hydrograph computed at the outlet of the catchment $($Point $2$ in figure $4),$ change if it travels through a reservoir at that location.

$($Answers$)=$ Peak discharge, $1\mathrm{.}29$m$^3/$sec

Tme to peak $=30$ mins
