Source: github Introduction Outfall nodes are terminal nodes where water leaves the simulated system. You can define the boundary conditions of outfall in SWMM5 as, Critical or normal flow depth in the connecting conduit A fixed stage A tidal stage A user defined stage vs time series XPSWMM provides similar options…

source: github Introduction To model an underground storage unit shown below is straight forward, you just need to define the storage curve of the tank and the manhole. …

source: github Introduction The hydraulic theory of a force main is quite simple, water flows pressurized inside the pipe, and the in and out flow rates are the same. We only need to get the friction loss and the minor losses (entrance and exit loss, etc.) correctly accounted for. …

source: github Introduction Screen is modeled using the Kirschmer’s equation in ICM. Refer to this Reference PDF on pg 5 for more information. As shown above, it is an empirical equation based on the configuration of the screen. Field measured data probably will be needed for more accurate results(refer to this…

source: Github, Innovyze Support Portal Introduction Modeling the head losses through a junction can be tricky because the losses are not directly captured by the differential equations that govern the flow through pipes. Therefore, it is up to each software package to decide how the losses are accounted for. As shown…

source: Github, Innovyze Support Portal Introduction When a pump is turned on, it will take some time for the flow to ramp up from 0 to its pumping capacity. Just like it takes a car some time from stop to reach 60mph. However, when we are modeling pump, that might not…

source: Github, Innovyze Support Portal Introduction InfoWorks is a powerful platform with thousands of functions. Ruby scripting is a great way to automate repeated or tedious modeling tasks. However, getting started with Ruby scripting can feel quite intimidating. If your job involves moving a lot of data in and out of…

source: github, Innovyze Support Portal Introduction Modeling a pump can feel challenging if you are not familiar with the concept of how a pump works. In this article, you’ll learn a very simple fix flow rate pump can be complicated, too. Here is the model, we have a very simple model…
