Groundwater fluxes boezems #460

Description

@rbruijnshkv

I performed a small check on the groundwater fluxes for the coupled LHM with the offline groundwater fluxes. I noticed that the yearly maximum drainage and infiltration fluxes in the boezems are zero for both infiltration as well as drainage. The boezems in peilbeheerst NL only have a doorgaand bakje, not a bergende. This error will be small for water authorities with relatively small areas of boezem (i.e. Scheldestromen), but is significant for Zuiderzeeland.

Below I have only plotted the values for the bergende bakjes. If a bergende bakje was not present, the doorgaand bakje has been chosen.

Maximum daily drainage per basin for the year 2017:

If the model is validated on these offline budgets, it is (for Zuiderzeeland) crucial to fix. Is this something you can look into @HendrikKok?

Follow up question: will the fluxes be correct with an online coupling if there is no bergende bakje?
