Freeboard in Results

When freeboard is exceeded from something like a basin, it is not immediately clear in the stormwater control results. It says flood risk and a water level that eats into the freeboard, but it does not flag up that this is an issue and is easily m...

Infiltration trench with varying depth.

It should be possible to design an infiltration trench where the long slope at the base of the trench is different to the slope at exceedance level i.e. the depth of the trench varies. Extremely useful for designing a trench that does not match fa...

Slope in %

It would be very handy if the slope input option of % be present regardless of Regional settings; being just 1:x is an important limitation; also, if the slope in % could be shown in the section views, would be nice.

HEC-22 Inlet reporting

The "Export HEC-22 Result to Excel" button in the calculator only includes results. Looking at flexible reporting, the HEC-22 data is only input, so I then have to use the results data from the calculator and the input data from flexible reporting...

Changes to a network do not propagate downstream

If you change a pipe diameter or gradient, it will not accommodate these changes in the downstream section of the network. For example upsizing and steepening a pipe in the middle of a run will mean the next pipeis undersized and goes uphill. It a...

Add check dams as a feature for swales

Add a check dam setting with height, notch weir and interval settings to simplify modelling swales on sloping sites. This avoids having to model several sections of swale in order to use the available storage.

Reporting of velocity through swales

If you design swales using Stormwater Controls (Swale) you will not be able to see simulated velocities through the swale. I believe you could try modelling as an open channel connection but you won't get infiltration through the sides & base.

Chezy Formula option

It would be useful to have a direct input for Chezy coefficient as an alternative to mannings n as some regions need to use this as an input and report on this too - this would result in less workaround and data manipulation

Allow a underdrains to have a different slope to the SuDS feature

Allow a storage structure such as dry swale, bioretention area or infiltration trench to have a different slope to the underdrain. Currently the underdrain has to follow the slope of the feature, which is not a real life representation of how they...

Incorporate the ability to create custom grate inlets. Currently InfoDrainage only allows for HEC22 defined inlet grate types to be used.

Some municipalities across New Zealand and other parts of the world require designers to use specified inlet grate types with defined inlet efficiency curves. There are two ways in which the custom inlet grate type this can be incorporated into In...
