WinTR-20 Advanced Features March Diversion options Divert flow over a certain value. Divide flow based on two rating curves. Send diverted flow outside the watershed. Send the diverted flow to another stream reach.

WinTR-20 Advanced Features March Diversion example

WinTR-20 Advanced Features March Time Analysis Time 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 ?
