Hello,

I am working on the storm water management of a city, through SWMM. For this to be possible, I need to have the elevation of every drainage element, which I actually do not have. However, I do have the topography of the area I am modelling. If we make the assumption that the drainage elements are situed more or less close to the surface (depending on the elements), is it possible to attribute and interpolate the elevations of my drainage elements with reference to the topography information, or my DEM ?

There are some threads that discuss how to do that:
