Question

At a station, storm i of 5 hour duration with intensity 2 cm/h resulted in a runoff of 4 cm and storm ii of 8 hour duration resulted in a runoff of 8.4 cm. assume that the ϕ-index is the same for both the storms. q.54 the ϕ-index (in cm/h) is:

Answer 1

Answer:

2.25 cm/hr

Explanation:

x=Intensity of storm II in terms of cm

As given condition, ϕ1 = ϕ2

(10-4)/5=(x-8.4)/8

on solving, x = 18.0 cm

Intensity of storm in cm/hr = 18/8 = 2.25 cm/hr
