Select waterlevel

Hi Support,

I'm tryging to make a panel that shows me the rise of the waterlevel in waterbody in a certain area after a Rainfall event. Is this possible? Can I use SELECTHEIGHT and WATERDEPTH_M?

I got this so far




  • Hi Ward,

    The Height clause can be used to get the height value of the terrain, but not the waterlevel for example. See also:

    For your panel you could use the SELECT_GRIDAVG_WHERE_AREA_IS_something_AND_GRID_WITH_ATTRIBUTE_IS_neerslaggebeurtenis to get the average value of the grid in your area. Would that work for your use case?

  • Hey Godelief,

    Thank you. In your sollution the AREA has to be the water, right?

    Could this work as well? The AREAISsomething is just used to select a specific area in my project. I can add TIMEFRAME_IS_x to get the waterlevel at a certain moment.


    and devide it by


    (Terrain 3 = water)

    What do you think? Would this work?

  • Hi Ward,

    Yes, the waterbody is then the area and the grid can be the Surface last value result type.

    I think the outcome of your second question will also be the Gridavg. Because the Gridvolume = the surface area (the landsize) * the average grid value (the gridavg). If you then divide this by the surface area (the landsize) you will get the gridavg.
