Flow

The mimimum pipe length in Flow is currently set to 1m. Where modelling junctions and connections there may be less than 1m between the junctions. Please revise the minimum length to around 300-500mm.

Within Microdrainage there was a function (Save Hydorgraph (HYQ) Data) for creating a depth Hydorgraph which can then be used for Flow to calculate a submerged outfall into a flooded area, could a similar function be provided within Flow

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...

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...

Where there are different infiltration rates (as the deep bore passes through different soils) it would be helpful if Flow was able to replicate what has possible in other software for some time, where these can be applied based on the sub soil ma...

There has been an update to FLOW where you know have to go into the storage tab to adjust the porosity, the base coeff, the Side coeff, the surround shape and Diameter. (say for a filter drain) You used to be able to change all of this from the sk...

There is often need to hide certain pipes from the final output. Either they are dummy pipes that have no relation to the final layout or they are areas outside the specific design network that do not need to be included in the report. Microdraina...

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...

Currently when the Link Hydrograph Output is exported to Excel to cells are locked and the user is unable to create graphs etc. as these are greyed out. There is a work around in that the entire output's values can be copied into a new spreadsheet...
