If a 4-hour unit hydrograph of a basin has a peak ordinate of 80 m^3/s, the peak ordinate of a 2-hour unit hydrograph for the same basin will be
HydrologyHydrologyMEDIUM
Choose the correct answer
A
equal to 80 m^3/s
B
greater than 80 m^3/s
C
less than 80 m^3/s
D
between 40 and 80 m^3/s
Correct Answer
B. greater than 80 m^3/s
Why is this the answer?
A shorter-duration unit hydrograph is sharper and therefore has a higher peak ordinate
