एक विशेष जलग्रहण क्षेत्र (catchment) में, φ-सूचकांक (φ-index) 0.4 सेमी/घंटा पाया गया। यदि 8 घंटे के तूफान के दौरान कुल 2.4 सेमी की वर्षा समान दर से होती है, तो जलग्रहण क्षेत्र पर परिणामी प्रत्यक्ष अपवाह गहराई (direct runoff depth) कितनी होगी?

The ratio of rainfall in a particular year to the Average Annual Rainfall (AAR) is defined as the:

A unit hydrograph represents a direct runoff hydrograph resulting from one unit depth of:

The peak of the outflow hydrograph will occur at the point of intersection of the inflow and outflow curves in which of the following cases?
