The ordinates of a 1-hour unit hydrograph (UH) at 1-hour intervals starting from t = 0 are 0, 13, 50, 80, 95, 85, 55, 35, 15, 10, 3, and 0 m3/s. These ordinates are used to derive a 3-hour UH. The peak discharge (in m3/s) for the derived 3-hour UH (rounded off to the nearest integer) is:

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?
