Question:

The ordinates of a 1-hour unit hydrograph (UH) are given below.
Time (hours) 0 1 2 3 4 5 6 7 8 9 10 11
Ordinates of 1-hour UH (m³/s) 0 13 50 80 95 85 55 35 15 10 3 0
These ordinates are used to derive a 3-hour UH. The peak discharge (in m3/s) for the derived 3-hour UH is _____ (rounded off to the nearest integer).

Time (hours)	0	1	2	3	4	5	6	7	8	9	10	11
Ordinates of 1-hour UH (m³/s)	0	13	50	80	95	85	55	35	15	10	3	0
