Question

Determine the direct runoff and streamflow given the following unit hydrograph. The rainfall is collected at 4-hour intervals and is measured as follows: 2, 3, and 5 cm. The rainfall infiltration rate is 0.3 cm/hr. The baseflow is 22 m3/s.

Answer 1

Answer:

See explanations

Explanation:

Thus, for this solution.

VDRH = (200+650+1050+750+600+400+200+75) m3/s (3600) s = 14'130,000 m3

3. Express VDRH in equivalent units of depth:

VDRH in equivalent units of depth = VDRH/Abasin = 14'130,000 m3/(282600000 m2) = 0.05 m = 5 cm.
