Building drainage

[hcastrol]

Building implementation (IMDC):

• Building coordinates are defined in: bldfile = sfincs.bld
• Building properties are defined in: bprfile = sfincs.bpr

Steps:

• Rain is retained on building roofs (up to volume indicated in bprfile)
• Excess water is released through user-defined gutter system

Hi Hilario,

@maartenvanormondt made a cleaned up version of your code in PR #317 , could you run and test this version whether the outcome is still the same for your test model?

Afterwards I'll have a more detailed look into the implementation myself, thanks!

Hi Tim,

We’ve done some checks on your implementation at both small and large spatial scales. For the small-scale test model, we only found minor differences at the discharge cells of the gutter system. At the larger scale, with a uniform water distribution around the buildings, these differences are negligible. So it looks good on our side.

My colleague Rob Schepper will be looking into the implementation of the run-off with the initialization implemented in the sfincs_initalization script. We will resubmit the pull request in the next days.

Best,
Hilario
