In a particular catchment, the φ-index was found to be 0.4 cm/h. If a total rainfall of 2.4 cm occurs uniformly during an 8-hour storm, the resulting direct runoff depth on the catchment will be:

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?
