The purpose of this TechNote is to help you understand the OpenFlows Hydraulics and Hydrology (H&H) functionality in Drainage and Utilities ( previously Subsurface Utilities), within Bentley's Civil products. It explains which programs it is available in, and the availability of Hydraulics & Hydrology tools within them.
The OpenFlows - Hydraulics and Hydrology functionality that is available in the OpenFlows SewerGEMS, CivilStorm, StormCAD and SewerCAD products was introduced in the SELECTseries 4 (SS4) version (08.11.09.845) of Bentley Civil products. Prior to that Subsurface Utility Engineering (SUE) tools were introduced in SELECTSeries 3 Civil products (version 08.11.09.674+). Since then the CONNECT Edition products have been introduced. These supersede the MX, InRoads, PowerCivil and GEOPAK products.
Here is the list of Civil products for which OpenFlwos - Hydraulics and Hydrology functionality is available:
Note: this does not apply to these products if they are used in the AutoCAD environment.
OpenFlows - Hydraulics and Hydrology functionality within Drainage & Utilities will help users design and analyze all underground utilities, in a single product. Hydraulic model data is stored in a SQLITE file imbedded into the DGN file.

OpenFlows - Hydraulics and Hydrology Functionality - how it works in civil products
With the availability of the Drainage & Utilities tools within your Civil products, you can perform the following things:
A Storm or Storm Sewer file can be updated in standalone and opened in Subsurface Utilities using the steps below:
1) Open the .DGN file using any of the hydraulics and hydrology Select Series 5 or CONNECT version standalone products.
2) Update and save the file
3) Open the file in one of the Civil products.
4) Go to the Subsurface Utilities Menu > Tools > Synchronize Drawing... The file should update.
Tools of OpenFlows storm-sewer products available within Subsurface Utilities tools.
Added support for UK Flood Estimation Handbook 2013 Rainfall Data starting with 10.09.00.91 version.
Tools not available from OpenFlows products
Each version of OpenRoads/OpenSite uses a certain version of the underlying OpenFlows technology for drainage. When the need arises to open models between these products and the OpenFlows products (such as SewerGEMS or StormCAD), one needs to consider the corresponding version to ensure compatibility.
