I have just started working with SWMM and wonder how to efficiently perform long term simulations respective do the extreme value statistics. What I need is a table comprising extreme values in terms of water levels above ground level of flood volume for all manholes affected by flooding during the simulation period. In the GUI of SWMM it is only possible to calculate the statistics for a single manhole by using the Statistics function. Maybe it is possible to run this function automatically from the command line providing the desired statistics for all manholes in text format. Otherwise, I need to derive the statistics from the time series of manhole water levels.
Does anyone have any recommendations for what is the best I can do in this case?
Thanks a lot. Christoph
