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

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?

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.

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.

CIRIA make a tool for valuing the benefits of green infrastructure. The results enable users to understand and quantify the wider value of SuDS and natural flood management measures. Being able to include this in the drainage design when comparing scenarios would be useful.

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.

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

Developers obviously have no idea how useful this was!
Thanks.

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!

Support a wider range of linear drainage channels.

Add a link to take drainage design data into Innovyze's InfoAsset Asset Management Software to complete the cycle of design - build - manage - maintain cycle.

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

Add Tree Pits as a type of SuDS structure.

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

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

In Source Control -> Cascade option allow the ability to run multiple rainfall datasets.
