Rainfall intensity = 2 cm/hr
Rainfall depth(cm) = 2 cm/hr × 3 hr = 6 cm
Runoff depth = Rainfall depth – Evaporation losses – infiltration losses
Runoff depth = 6 cm – 0.8 cm – 1.6 cm
Runoff depth = 3.6 cm
Rainfall depth(cm) = 2 cm/hr × 3 hr = 6 cm
Runoff depth = Rainfall depth – Evaporation losses – infiltration losses
Runoff depth = 6 cm – 0.8 cm – 1.6 cm
Runoff depth = 3.6 cm
