In a reservoir with uncontrolled spillways, the peak of the (routed) outflow hydrograph
HydrologyHydrologyMEDIUM
Choose the correct answer
A
lies outside the plotted inflow hydrograph
B
lies on the recession part of the plotted inflow hydrograph
C
lies on the peak of the plotted inflow hydrograph
D
is higher than the peak of the plotted inflow hydrograph
Correct Answer
B. lies on the recession part of the plotted inflow hydrograph
Why is this the answer?
For an uncontrolled spillway, the outflow peak occurs where the outflow curve crosses the recession limb of the inflow hydrograph (maximum storage).
