OpenFlows FLOOD CONNECT Edition Update 3 | 524.4 mb
The Hydraulics and Hydrology development team is pleased to announce the availability of OpenFlows FLOOD CONNECT Edition Update 3 (build 10.03.00.01), is a complete flood modeling software for understanding and mitigating flood risks in urban, riverine, and coastal areas. What's New in OpenFlows FLOOD (10.03.00.01) The latest release of OpenFlows FLOOD introduces various updates to the previous version as well as addition of new features, tools and functionality to improve user experience, results interpretation, and to provide a more holistic approach towards modeling. We shall go over these updates and features in detail below. What's New in OpenFlows FLOOD (10.03.00.01) Enhanced Licensing: Subscription Entitlement Service
This release uses Subscription Entitlement Service Type Licensing (formerly known as CONNECT Licensing), a major advancement in Bentley's product licensing methodology. Subscription Entitlement Service Licensing gives organizations much more control over license usage and reporting, with the capability to establish concurrent use thresholds, group users with different levels of access and more. More information on Subscription Entitlement Service Licensing and how it works can be found here: Licensing OpenFlows products - Subscription Entitlement Service
Improved Engine Performance
OpenFlows FLOOD now uses an updated and optimized MOHID Water engine which has resulted in a significant improvement in computational and simulation performance by about 30%.
Additionally, an updated MOHID Land engine enables a more efficient 1D-2D model computation by removing the obsolete OpenMI interface. This improvement allows a reduction in computational time by roughly two-thirds when using a high number of (1D) OpenFlows SewerGEMS nodes.
Improved User Interface for Configuring Model Options
The latest release has now a property grid for configuring input data files which would replace the older file editor which was present in previous versions of FLOOD.
The new improved user interface allows for a much easier workflow to configure the various input parameters required for analysis and simulation in FLOOD. This would also minimize the chances of input errors using the older file editor.
The user interface has various instances; drop down lists of calculation options which makes it easy to setup your simulation. In addition to this, you can directly call your configuration files (.dat) by browsing to the folder location where they are stored rather than manually typing out the path to the folder.
SWMM to MOHID Land Connectivity
With this release it is now possible to link 1D (SWMM) model files (.inp format) directly to the 2D (MOHID Land) engine, preserving the hydrology data originally created in the 1D model.
This tool can be accessed in the Toolbox Menu under Urban Floods (Toolbox > Urban Floods > Connect SWMM model to MOHID Land model)
In the earlier versions of FLOOD, the connectivity with SWMM models was already available, but the hydrology data associated with the 1D model would be automatically removed during the import process. This was to avoid overlap with the 2D MOHID Land engine which requires the hydrological processes to be directly computed in the 2D environment of OpenFlows FLOOD, calculating the run-off based on the direct rainfall (precipitation).
This is not required with the latest version. The user now has the choice of using the hydrology associated with the 1D model in OpenFlows FLOOD. Although using the direct rain on 2D grid is more realistic, in some cases, it might be more efficient to use hydrology previously configured in the 1D engine and might also significantly decrease computational time.
When connecting the SWMM model to MOHID Land model the above window comes up. The option to keep SWMM hydrology can be seen as highlighted. There is a check box next to it which allows the user to opt for including or excluding SWMM hydrology connected to their 1D model.
Dam Break Outflow Hydrograph generator tool
With this new release there is addition of a new tool to generate dam break hydrograph discharge, This is the outflow hydrograph attributed to the sudden release of water in reservoir storage due to a dam break, based on the dam’s physical aspects and reservoir's storage information. It applies the United States Department of Agriculture’s Technical Reports TR-60 and TR-66 methodology for simulation.
This tool can be accessed in the Toolbox Menu under Time Series (Toolbox > Time Series > Generate Dam Break Outflow Hydrograph Time Series)
The data input for this tool looks like this,
These are the default values specified which can be changed as per the dam and reservoir specifications.
Note that in the Disclaimer section, a link to the USDA Technical Reports page is given which is the same as above.
New Visualization Features Axis vertical cut tool to visualize vertical profiles in 3D data
A new axis vertical cut tool was included, which allows visualizing vertical profiles from 3D polygon based HDF File layers. The tool allows to visualize XZ or YZ profiles.
The tool can be found under Toolbox > Visualization > Axis vertical cut.
Adaptive smoothing
OpenFlows FLOOD includes now an adaptive (median) smoothing filter applied in the image rendered. This new feature allows the visualization of model results with less “noise”, as can be seen in the next images.
The option to do this can be found when you right-click any result file (.hdf5 format). The option for adaptive smoothness is available with a range of smoothness to be specified.
Once this option is checked on, the results would be enhanced by the adaptive smoothing applied. Below are some comparative results for flooding before and after adaptive smoothing is applied.

Better handling of raster data
When loading a raster data file into the OpenFlows FLOOD map, the current release includes new features such as automatic color scale adjustment, facilitating the process of visualizing the raster data.
Viewing network labels on map
To connect a SWMM model or a SewerGEMS (or CivilStorm) model to the MOHID Land (2D) engine, there’s now the option of visualizing the 1D drainage network labels on the map. This new feature is useful when the user wants to check specific 1D nodes or pipes and its correspondence in the 2D grid.
This option is available at Toolbox > Urban Floods > Connect SewerGEMS model to MOHID Land model. At step 3 of the menu this option is available.
Once this option is selected, the labels associated with the SewerGEMS or CivilStorm model would be visible in the map.
Conversion of TIN files to XYZ format Direct conversion of TIN geometry files to MOHID XYZ format is now possible using a new tool available in the Toolbox section. With this new tool the user can directly bring in their TIN geometry data and convert it into the OpenFlows FLOOD accepted XYZ format.
This tool can be accessed in the Toolbox Menu under File Conversion (Toolbox > File Conversion > TIN to MOHID
Launching this tool will open up a dialog box where you can specify the location of your TIN file and where you want to store the converted XYZ format file.
This feature will improve the workflow of model building by saving time spent in converting TIN files to XYZ formats outside of OpenFlows FLOOD environment.
OpenFlows FLOOD is a GIS-based platform to analyze and simulate flooding in urban, riverine and coastal environments. OpenFlows FLOOD uses numerical models to simulate a range of hydraulic and hydrological processes that occur in river basins, including rainfall, infiltration, surface runoff, channel flow, and groundwater flow in a visually rich environment. In urban areas OpenFlows FLOOD can connect to a SewerGEMS or CivilStorm stormwater network to dynamically simulate stormwater flow and surface runoff in a 2D environment. OpenFlows FLOOD is also integrated with ContextCapture and LumenRT, allowing the ingestion of the topographic data obtained in ContextCapture as an input to the surface runoff model, and then to visualize model outputs in an immersive and visually striking 3D reality modeling interface as provided by LumenRT.
