Version 12.0 Beta

Why is Version 12 a Beta Version?

Important note: With regard to shear stress calculations, nothing has changed from earlier versions of PC-Convey (that included shear stress calculations) to Version 12.10B.

The Constructed Waterway Designer is a relatively new tool developed by Integrity Software for designing and analysing waterways through new developments. It vastly simplifies the process of determining the dimensions required for a waterway to carry a low flow (e.g. a 3 month flow) in its Low Flow Channel and a high flow (e.g. a 1% flow) in the High Flow Channel, including a user-specified freeboard. The shear stresses on the cross-section can be checked and, if too high, the cross-section can be adjusted quickly and the new shear stresses checked.

Integrity Software has obtained agreement from Melbourne Water and HEC-RAS experts that the mean shear stress obtained from du Boys’ equation must be factored up in order to estimate the maximum shear stresses on a cross-section. PC-Convey V12.10B factors the mean shear stresses up using relationships from the U.S. Federal Highway Administration’s Design of Roadside Channels with Flexible Linings (2005). PC-Convey can further factor up the shear stresses to account for bends. (A great deal more information on shear stress within PC-Convey V12.10B can be found by searching for “shear” (without the quotation marks) in Help\PC-Convey Help – Index and browsing the three topics there.)

Extensive testing of the shear stress calculations in the new version of PC-Convey has been undertaken, particularly for constructed waterway cross-sections, which is what these calculations were mainly introduced for, however the software will provide shear stress results for any cross-section and it is not feasible to test all possible cross-sections.

Consequently Version 12.0 was released as a Beta version to gather feedback from the industry, with the plan being to release the final V12.X after a period of approximately 6 months. However, this has proven to be a slower process than anticipated and so Version 12.10 is still being considered a Beta version. Customers with a current AMA will receive this update at no further cost.

Please provide any feedback on the new (or any) features of the software, including any issues you discover.
