+What is aco Hydraulic design?
This unique ACO Hydraulic Design software is built to enable the efficient and accurate hydraulic design of surface water management schemes using channels as the means of conveyance.
Powerful project based software
- Create catchment models that are fully editable
- Easily change design criteria (rainfall intensities, product type, additional runs)
- Quickly and confidently assess any alterations
- Own allocated space to store designs
- Designs are kept confidential on the server
- PDF summary document.
ACO slope systems are available with design support. Please contact ACO Design Services on 01462 816666 for more information.
To get started click on the video demonstration below which will guide you through the software.
The ACO Design program uses the "spatially varied flow" differential equation for steady non-uniform flow in channels to evaluate the backwater curve profile of the water within the channels. This dynamic equation gives the correct analysis of flow in a channel accepting flow all along it's length, and enables accurate calculation of flow in channels of stepped size. The program also allows the inclusion of end inflow and point inflows into the channel.
It should be noted that other software, using empirical formulae such as that from the HR Wallingford Report SR581, will not give the correct results for stepped channel systems; they will considerably underestimate the required channels size.
