2D stormwater modeling in Civil Storm and Sewergems

Bentley recently acquired MOHID Studio, which can perform 2D simulations. We are actively looking into integrating that with SewerGEMS and CivilStorm.

See: 2D Modeling of Urban Flooding

Does that mean we need to get separate license for MOHID Studio? is there any plans for Civil Storm / SewerGems to become Integrated Catchment Modeling Solution on their own? 

I kind of knew 2D urban flood modeling was not yet included but something lead to this question.

I attended an event where a consultant showed a presentation on hydrodynamic modeling and simulation that featured some form of urban flood modeling that is said to be  done in SewerGems (the presentation slide cited SewerGems as the tool). Basically. while looking at a plan view of the developed site, at a point in time, stormwater, in excess of the drainage network capacity, started spreading on the road surface up to  point in time when max extent of flood was reached and then water ponding started receding till water disappeared (eventually drained back into the network)

I was wondering if this simulation was facilitated by a "Ponded Area" surface storage option for manholes and catch basins. Can this be represented in plan view to show the above and how is that possible without 2D simulation and a digital terrain

I got other answers during the event that caused confusion but I will keep that out of here for the moment

Hello AHQ.

• Whether that will be a separate MOHID studio license or you can use one of your existing, this question cannot be answered at this moment. Since we are still looking into integrating it with SewerGEMS or CivilStorm and will publish our views about once we are with the outline of this integration. 
• You can visualize the surface storage option with the help of graph, to know the amount of overflow and its extent. 

            Depth (flooding) will give you the depth of overflow which will vary with the time or you can also graph for flow (overflow) over the time. 

            Or you can also color code these result fields to view in the plan view. 

Interpreting results when using manhole or catchbasin Surface Storage 

the graph view is a standard way of seeing things that I'm familiar with and is not what attracted my attention leading to me asking the question. What I saw is, and i will repeat from my original question:

"while looking at a plan view of the developed site, at a point in time, stormwater, in excess of the drainage network capacity, started spreading on the road surface up to  point in time when max extent of flood was reached and then water ponding started receding till water disappeared (eventually drained back into the network)"
