Clarify roof height measurement for weirs or reference roof height by absolute elevation rather than relative to weir crest

The current help documentation for weirs would benefit from stating where the roof height is measured from (crest of weir). If possible, it would be best to reference the roof height by its level/absolute elevation so that users do not have to change two fields when lower/raising weir crests.

    Thank you for raising this and thanks to those who voted. Here is the answer for your question:

    The height field of hw_weir has units of length (Y, native m), not level (Z, native m AD), so is relative to crest.


    I have also instructed the help documentation team to update the help page accordingly. I will move the status of this to launched since the question has been answered and the help page update is already on the backlog.

    Wll keep you updated once that is concluded and whilst this case is being looked at by our documentation team, here is the answer for your question:
