EPA's Storm Water Management Model (SWMM) is used throughout the world for planning, analysis and design related to stormwater runoff, combined and sanitary sewers, and other drainage systems in urban areas. There are many applications for drainage systems in non-urban areas as well.
SWMM is a dynamic hydrology-hydraulic water quality simulation model. It is used for single event or long-term (continuous) simulation of runoff quantity and quality from primarily urban areas. The runoff component operates on a collection of sub catchment areas that receive precipitation and generate runoff and pollutant loads. The routing portion transports this runoff through a system of pipes, channels, storage/treatment devices, pumps, and regulators.
SWMM tracks the quantity and quality of runoff made within each sub catchment. It tracks the flow rate, flow depth, and quality of water in each pipe and channel during a simulation period made up of multiple time steps. SWMM also models the hydrologic performance of specific types of low impact development (LID) controls.
Dear Alban, I know these two models, but I've never used.
I hope it may help you.

HEC-RAS,HEC-GeoRAS, HEC-HMS, HEC-GeoHMS, MIKE Urban, MIKE 21, MIKE Flood...Please go through it.. All are best models for urban studies..
I think there is Not a common or Best solution for a complicated problem like Storm modeling. but there is an EPA model which match your need. SWMM. (Storm water management modeling).
it is applicable were you want model the runoff water of rain in Cities and it is able to model rain falls whether it's a single event or a continues phenomenon,

what type of data is needed for HEC RAS . Is it suitable for small reaches in a city. Does it have any impact on results, as it is I D
you need to be more precise with respect to your criteria, which will allow to consider a software product as "the best". There are also many factors, which should be taken into account while modelling of inundations in the urban areas : storm drainage system and infrastructure are the most important and for that reason any 2D/3D modelling system will be a recomended choice.
Depends on your research question and what type of results you are after. If you are not interested in 2d flood maps, then SWMM is the most commonly used. They have 2d versions also but thats not free. Mike packages are also famous in dealing with urban water problems but they are never free brother

It depends on the field conditions of the urban area such as existing drainage systems, and the output results you wanted. If you have the data for existing drainage systems (e.g. pipe/channel sizes, invert elevations, etc.), Autodesk Storm and Sanitary Analysis (SSA) or SWMM may be a good choice.
Others such as TR55/TR20 (they are simple) can also be used to simulate the hydrograph (TR20 has the channel section input to simulate flood). For floodplain mapping (the area has rivers), Maybe you can use HEC-HMS/GeoHMS (GIS-Based), HEC-RAS/GeoRAS(GIS-Based) to get your flood mapping and elevation grid.
It all depends on whether you want a 1-D, 2-D, or 3-D simulation, the catchment characteristics, and the availability of data. HEC-RAS coupled with HEC-HMS, or SWMM can be a good option. Alternatively, you can use Info Works or MIKE which are quite pricey.
It depends on what is your requirement. HEC RAS along with HEC geoRAS will be an option that can be tried out.
Dear Alban,
I think it's hard to get a good answer to your question, as very few people have enough experience to determine the quality of a range modelling software themselves, as it takes years to really become an expert in any software.
You do need to match the software to your model area(s) though; for example are you just looking at a pipe network, or do you also need to have overland flooding and river flooding in your model as well? Are you investigating water quality and pollutant transport etc? You need a software package that can model all your requirements, which often means you need a coupled model package (1D-2D) to get the most reliable results.
You do have a wide range of options though, as stated in the responses to your Q. Some are free to use for anyone, and some have a price tag for commercial use. It's worth to point out, though, that even the commercial software are often free for some University employees (for example PhD students), so it might be a good idea to send enquiries to the developers of the software to see where you can get the best package deal.
I'll get you jump started and tell you that you can send an inquiry to [email protected] to get some information regarding what options are available for MIKE products. You should also do the same for other developers but I only know the email to DHI as I work there.
Good luck!
Best regards,
Jonas
If you are looking for free softwares, check out LISFLOOD. I guess tehy have it as open source
By far the best I have used to date is the ANUGA model. It has the benefit of a flexibly sized mesh so can model very fine detail including for instance bridge piers if desired. But also entire catchments with spatially distributed rainfall over the entire catchment.
Hi Alban,
There are many software that can be applied for urban area.The choice of model is depend upon the how detailed you want to analyze.
If ample of resources and good quality data is available, you can go for Mike 11/21, Infoworks. These are paid software and required detailed data.
If you have limited resource you can go for HEC-RAS and SWMM.

For my self i much prefer to use MIKE and TURFLOW to get 1D, 2D and 3D flood model, it depend on your specific requirements on how detailed you need to be
MIKE FLOOD
MIKE FLOOD is a complete toolbox for flood modelling with flexibility in model couplings. It allows you to simulate virtually any flood problem in rivers, floodplains, urban and coastal areas.
MIKE URBAN is the modelling software package for all urban water modelling activities. You can maximise your productivity and fully leverage your investment in GIS and water modelling software tools.
Hydro_AS-2D is good for heavy rainfall analysis/ urban flash flood modelling and have a nice scripting API: https://www.hydroas-2d.com/
The open source CFD code OpenFOAM can handle 2D flood modelling:

PCSWMM is more powerful model if you have an access to get licensed software. It is updated form of SWMM model.
