What are the data required to simulate Urban Flood scenario for a Urban catchment using SWMM ? Further for model calibration and validation what necessary information needed?
You can download the manual given in the link below. It serves as a practical application guide for new SWMM users. It contains 09 worked-out examples that illustrate how SWMM can be used to model some of the most common types of stormwater management and design problems encountered in practice.
2- All pipes, culverts, ditches, gutters, channel, vaults, detention basins, slope of streets (longitudinal and cross), Information of DIs, pumps, ... location, dimensions and roughness.
3- Hydrology of the location for the rainfall
4- You have to have the local, or city or state manual to find which design rainfall and which hydrology and routing method
5- Land use, parcel , future development land use and other systems in your location of study (for example if there is sewer pipe) Surrounding watersheds if there may be a over flow to your area ...
The above-mentioned you need to build model.
To validate that you have to have some measured volume or stage information with rainfall information so you run your model with the loading of that rain fall and check versus that stage/volume or spread or ...
