The solution of node depths and link flows in SWMM 5 is an iterative process but the number of iterations for the flows and links depends on how fast the node depth converges. The node continuity equation is ALWAYS solved at each iteration for eac...

I am having trouble doing something that I have done a thousand times before, I am trying to directly input flow data into a node, for whatever reason, it refuses to accept it. I go to time series editor, name it, paste it in, view it, and then go...

I am trying to locate a "typical years" rainfall for the Pittsburgh region for use in a model. I am trying to get away from the single event design sotrm modeling but don't have the resources to analyze 50 years worth of data to find the a years' ...
