Dear researcher,
I would like to understand better which are the most suitable tools to carry out pluvial flood simulation.
In particular, the interest is focused on the ones able to implement dual drainage models (coupling 1D drainage network and 2D overland flow).
Multiple commercial software can satisfy these requirements, such as Infoworks ICM or Mike+, but what about freeware/open source?
Any comment, suggestion or shared documentation is really precious.
All the best
Hec-Ras in one of the most used software for flood simulations.

Dear Jamel Chahed thanks for your answer.
HEC-RAS is surely the most famous software in this field.
My question was more related to the numerical models available to carry out pluvial flood risk assessments, meaning software able to implement dual-drainage models. This allows simulating simultaneously surface and underground runoff propagation.

A very good (but not open source) software is FLO-2D. In addition to being able to model surface runoff it allows coupling of drainage system modeling to EPA-SWMM (open source). In addition, exchange flows on the water table (from top to bottom and vice versa) can also be modeled via coupling with MODFLOW.
Compared with HEC-RAS, it also allows only the zenith forcing to propagate the runoff and does not necessarily require an input hydrogram.
Hello, I am also working on urban pluvial flood modeling but the problem is the lack of data availability. My study area has no ground-based data such as drainage network data, hydraulic data, etc. I am looking for any useful approach which can use satellite-based data for modeling and simulation.
Any comment, suggestion, or shared documentation is really precious.
Thanks
