CIVE 445 - ENGINEERING HYDROLOGY FALL 2008 - MIDTERM 2 - SOLUTION

PROBLEM 1

Drainage area = 70 ha

Rainfall intensity = 20 mm/hr

Runoff coefficient = 0.95

Peak discharge Q_p = 0.95 × 20 mm/hr × 70 ha

Q_p = 0.95 × 20 mm/hr × 0.001 m/mm × (1/3600) hr/s × 70 ha × 10,000 m²/ha

Q_p = 3.694 m³/s    ANSWER.
