Time AnalysisTime AnalysisTime analyses may assist with determining
economic damages caused by flood water. At any reach and cross section, the time at
which a particular discharge or elevation is exceeded may be determined.
For example, what is the time for which an elevation of 500 feet is exceeded at a particular cross section ?
