Dry swale Modelling workflow

Issue Summary: When modelling a wet or dry swale using the native swale element, the swale does not align to the existing ground profile. Instead, it generates a swale based solely on the defined parameters and the exceedance elevation from the pr...

Direct Runoff

Please allow for direct runoff with no transformation. Even with a Tc of 0, there is still some small amount of lag in applying the rainfall hydrograph. In the absence of custom S-graphs, this would allow the user to conservatively demonstrate no ...

Japanese Standard Rainfall Intensity Formulas

In Japan, four rainfall intensity formulas (Talbot, Kuno-Ishiguro, Cleveland, Sherman) are used in sewerage planning, including stormwater drainage. According to a survey report by the Ministry of Land, Infrastructure, Transport, and Tourism, thes...

Additional 2D hydraulic results

For both the Deluge and the 1D/2D Analysis, it would be useful to report on additional hydraulic results than just the depth and D*V. Flow, Velocity and Water Elevation are also critical parameters required to report on, for example. Along with th...

‼️Improved Snapping and Placement Tools ‼️

It would be great to have additional snapping options—simple ones like end, midpoint, and intersection—to make placement more accurate. Currently, snapping is inconsistent and often doesn’t engage when expected. It would also help to clearly show ...

🔥Optimise Pipe Network Design by Updating Upstream Pipes Slopes in Profile View ‼️

💧 Add a feature that automatically selects all upstream pipes from a chosen junction and updates them to a specified slope. This would streamline optimisation by removing the need to manually identify and adjust each pipe segment. It improves desi...

Resolve Design Wizard automatically introducing and accepting negative gradients along runs

The current design wizard in InfoDrainage, even when all design criteria are set to standard, allows for negative gradients to be included within the model and can often be missed without careful inspection or auditing. This then relies on going t...

Allow different C-values (runoff coefficients) for major and minor storms

It would be nice to have an input for different C-values (runoff coefficients) for various storm events. In CO we have different coefficients based on the storm event which contributes to the flow calculations for the Rational Method. Currently yo...

Loss Method - Fraction with Maximum Loss

Hi - in SoCal and a local agency uses SCS loss method to create an average yield fraction rather than the typical loss curve, but with a maximum infiltration loss rate to "clip" the peak loss rate. Can we have a modified SCS loss method with max l...

Custom S-Curves

Request ability to use custom S-curves similar to HEC-HMS. This would allow us to import custom S-curves rather than use default SCS DUH's for example. I'm in Southern California and the local Districts are very picky and use unique hydrology appr...
