Modelling Steeply Sloping Pressurised Pipes (click to open technical note)

A previous technical note covered the modelling of pressurised pipes within InfoWorks ICM and InfoWorks CS. This technical note provides a description of how to model pressurised pipes which slope (steeply) downhill.

In reality, it is possible that the top part of the pipe will be operating under free surface flow, whereas the lower portion will be heavily surcharged due to backing up from downstream. There is no ideal way to model this configuration, but the best approximation is to model the entire pipe as ‘forcemain’ and to ensure that it is pressurised throughout the simulation.
