Urban creep is an additional test which is not applicable to all runs. So would be more useful to not have a universal application of creep (to all storms). Would be better to have the facility to apply to selected storms only.

Te has specific meaning in the UK when using the rational method (modified).
Tc also has speific meaning (Te + sumTf).
It would be better if the software wants the user to input a Te, that it calls it Te. At the moment it calls the Te Time of concentration, which is very confusing.

DrawNet (CAD) compatibility with AutoCAD/Civil 3D 2021 version.

when I start a new network, the criteria automatically selects my default manhole and pipe size file, can you change it so when importing a file for the first time it selects my standard default files, older versions did select the default file

to be able to change the default button in storm duration so I can set up my own default settings

MicroDrainage Network

It would be very useful if it was possible to change the dims of many manholes at once. It'a a very laborious and time consuming task to change each dimension one-by-one, especially if the network is very large!

It would be very useful if there was a way for the true ground profile to also be exported on long sections. Currently, when exporting long sections from microdrainage, the true ground levels are only shown at manhole locations and a straight line is used to replicate ground level between the manholes. Could a 3D terrrain file possibly be loaded into microdrainage so that the true ground profile is shown when exporting long sections?

Add the ability to have a maintenance sheet in the print outs for SuDS structures.

Add Tree Pits as a type of SuDS structure.

Support the ability to create a biodiversity metric for SuDS structures as per the Defra tool.

Would be useful to be able to 'replace outline' of a stormwater control by importing a polygon (e.g. DXF, SHP etc), rather than the existing options which are just to redraw in ID only.
Every project there seems to be need to replace an outline from another drawing (as architechtural desisns evolve). At teh moment have to re-set up the control each time this occurs.

DSD import/export for MicroDrainage exists but HydroWorks is now dead. A more generic import/export would be beneficial for exchange of information with other drainage simulation packages and with GIS systems for existing networks; something similar to the import/xport functins in ICM would be ideal.

Would greatly simplify the process of getting results/details from MD into a report, skipping a stage in the current process (Export to CSV/Excel - Open)

Assessment of the annual water balance is an important criteria to evaluate drainage design at neighbourhood level.
Functionality to assess scenarios in a chart (similar to typical pre-urban vs. urban) would save time in GIS-postprocessing

The status bar currently only displays levels (ground model level, water depth) to 1 decimal place. 2 Decimal places would be much more useful, Especially to ensure a node is at a low point or in the gutter invert..

Can wall thicknesses be added to pipes and manholes to check clash detections

Enable the manholes assigned to impermeable areas on drawnet to be changed.
It is currently not possible to change the manhole when editing a network meaning the areas have to be deleted then recreated. Being able to change the manhole would save a lot of time.

Realistic flow through bioretention, permeable paving and other SuDS within hydraulic models.

Sometimes we are required by the LLFA to run storms <60mins with FSR rainfall and storms >60mins with FEH rainfall. This requires the "Seasonal Return Period Wizard" to be run twice following changes to the network and then exported in separate files.

It would be much quicker if this could be specified in the wizard.
