THE Semi Elliptical Section of SWMM, implements semi elliptical section galleries
The relevant geometry property for this section is the Maximum Height:
In SOLIDOS, the user must implement a property in the device constructor that describes that properties, for example:
Note: You can use the section generated by this activity to model the device's internal section and also to define
the Hydraulic Section of the linear device, as this is a mandatory property for dimensioning.
Note: The geometry shown is an approximation. In SWMM, there is no mention of the radius of the arcs
