I am working on a fairly complicated stormwater design with several interconnected ponds. My hydraflow model will calculate the entire basin routing and will give me a peak flow rate.When I look at the elevation vs. time graph for the basin routing I am finding that the "max elevation" Hydraflow is giving me is not necessarily true since the tabular elevations are showing a number in brackets like this <15.5>. In some cases the graph drops off straight to zero. My guess is that there is not enough storage in the basin but the program is forcing it to work? Has any ever experienced a similar problem? Any thoughts?
