a$.$ Considering a simplified, straight$-$line $4$:$1$ storage$-$indication curve, route the inflow hydrograph by filling out the table below with typing $($no hand$-$written work$).$ The water level is above the crest of the spillway when the inflow hydrograph arrives $($i$.$e$.,$ an earlier hydrograph is still being routed through the reservoir$).$ Continue the routing until the outflow discharge is of the peak flow of the inflow hydrograph. Add as many rows to the table as necessary.

b$.$ At what time will the routing end?

c$.$ What is the available storage volume at the time of peak outflow?
