Check dams are commonly used in swales to temporarily pond runoff to increase pollutant retention and infiltration and decrease flow velocity, but Flow does not have an option to model them. As they are a recognised SuDS feature, and commonly used...

When plotting long sections, it would be useful to be able to show the crossings from other drainage networks. The crossing are shown on the long sections viewer in flow but not when you plot them.

When sketching links, be able to draw polylines as well as add, move and delete vertices

Be able to change the shape of ponds in plan view

Have an advanced settings function for contributing or lateral areas so that land use/land cover characteristics can be applied like depression storage, Manning's n, and slope. Alternatively, be able to choose a land use/cover which will automatic...

Change the units for the area column in the time area diagram to m2 (or have the ability for user to change the units between m2 and ha). When using time area diagram, as per the Green Roof Runoff Method (link below), it results in areas of 0.001 ...

We currently running a few simulations in Flow for projects in the Middle East and we'd benefit from a feature that allows us to do quick storage estimates using rainfall profiles applicable to those regions. Flow currently gives the attached popu...

Global urban creep isn’t helpful. We have a process of assessing UC on a pipe-by-pipe basis. We separate the areas that UC should be applied to and areas such as flats the highway that don’t need it. If global UC is applied, then you are adding 10...

I have a request regards time to half empty of infiltration systems. Irrespective of what I set in the preference page (whether time to half empty by volume or by storm) I just get time to half empty of the structure. That isn’t very useful inform...

Currently Civil3D UKIE 2026 has an extensive parts list directly related to the DCG information. The set up also include pre-defined layers. When working with a design team using Revit it is useful to keep these pre-defined 3D features and layers....
