When create a Storm Water model equipped with catch basins elements and gutters; do we apply "Ponded Area" to the catch basins? Is it usually for the Manholes only or it is recommended to do applying that to the Inlets as well, especially we are creating a model for the existing system which already under sized and facing a flooding issues.
If it is recommended to add "Ponded Area" to the inlets, what is technical reason in terms of modelling ? and need an advise how to define that with respect to the curb's height and the flood volume?
