It is used to estimate the peak discharge of a flood event from the rainfall data. The unit hydrograph is constructed by dividing the peak discharge of a flood event by the rainfall excess, which is the difference between the rainfall and the infiltration. The time base of the unit hydrograph is the time it takes for the peak discharge to occur.<\/p>\n<p>The other options are incorrect because:<\/p>\n<ul>\n<li>Rainfall duration is the length of <div
