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...

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...

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...

Following recent liaison with Hydro International they could select the 'XC' Hydrobrake Objective within their API to specify the relevant products based on Design Depth and Flow. However, we can't select this option within the Flow Controls secti...

We have noticed that for high Flowrates (100l/s and 380l/s) on a recent project that the Hydrobrake Min Outlet and Node Diameters do not populate and return a zero value. It is our understanding that this part of Flow is using the API provided by ...

Particularly for the new dry swale modeling feature in V16 it would be good to be able to apply different infiltration rates at different depths. Modelling different structures with different rates is not as effective as having them within one str...

This is especially applicable now given some areas may have 100% impermeable while other will have greenfield with a possible option to turn to impermeable. Users can also adjust Cv value locally. The design report should contain the new additions.

Add a column called ‘Infiltration Volume’ to the simulation results table which indicates the total volume of water infiltrating into the ground at the upstream manhole during the selected storm.

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...
