I am creating a drainage system which at some point drains into perforated pipes.
How can i model a perforated pipe?
Hello Sepideh,
For this purpose you can use the Explicit (SWMM) solver (selected in the calculation options) > groundwater module. The aquifer can be defined under Components > SWMM Extensions > Aquifers.
Here is information on these SWMM extension and modeling aquifer.
How to model aquifers in SewerGEMS and CivilStorm using the SWMM solver
Please see below similar forum detailed discussion on modeling perforated pipes, for your reference.

To add to Sushma's response - if you only need a simple modeling of the infiltration of water into the perforations in an underground storage pipe, you could model this with the pond element in SewerGEMS, CivilStorm and PondPack, with either the infiltration method set properly in the pond properties, or a "user defined" composite outlet structure configured with the appropriate head vs. infiltration rate rating curve. See more in these articles:
Using the Average Infiltration (Seepage) method for ponds
How Infiltration is calculated when using the "Infiltration Head / Depth" method
How to vary pond infiltration rate with water surface elevation using an outlet rating table
If you need to model complex interactions with groundwater/aquifers, that's when the SWMM extensions can be used which Sushma mentioned.
