Chapter $4$

An inflow hydrograph is given for a reservoir that has a weir spillway outflow structure. The flow through tbe spillway is governed by the equation Q$=3\mathrm{.}75$Ly$^3/2($cfs$)$ where $L$ is the length of the weir and $y$ is the height of the water above the spillway crest. The storage in the reservoir is governed by

$S=300y(ac-ft)$

Using $t=12hr,L=15ft,$ and $S_0=Q_0=0,$ route the inflow hydrograph through the reservoir using the storage indication method.
