We have recently been challenged by Wiltshire LLFA regarding half drain times. As I understand it, Flow calculates the half drain time to CIRIA 156 which gives a significantly longer half drain time than the BRE365 method that Micro Drainage uses....

It seems that if a pipe has a swale upstream then the pipe uses the Manning's equations to compute flows etc, but if it has nothing upstream or a pipe upsteam then it uses the Colebrook-White equations. This means that on the same storm water syst...

There is an absence of guidance on the use of ReFH2 data in Flow. I understand from discussions with the Help Desk that they don't have access to the software. In the absence of reasonable guidance the ReFH2 features are worthless.

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 chainage, pipe bedding and node cover grade information as options for long section outputs. These are standard requirements for a lot of water authorities so would prevent manual changes being required to allow these outputs to be included.

There is a requirement to be able to produce design reports for separate sections of a larger Flow network when working on multi-phase developments.

When looking at the preliminary quick storage calculations used for preliminary designs/drainage strategies, the quick storage tool is excellent up until the point you want to design soakaways as there is no option to get a quick storage calculati...

We’ve noticed a significant increase in the use of precast manholes across nearly every development we’re involved in. The companies supplying these typically issue drawings where each incoming pipe is referenced by its angle relative to the outgo...

Having used Flow now for the last 6 months we feel there are plenty of user interface improvements than can be made. Add the link references in the results? When a link is selected, can the corresponding link on the section be highlight with a col...
