What is the best way to model Sea Level Rise?

I've made a model with a breach area of a location in Spain, but whenever i execute the Flooding overlay. I can only sea rising water levels on the seaward side of the breach (see the attachement).

Does anyone have a method to fix this?

    Hi Andy.arcadis,

    I had a look into your project. I noticed that you have modelled the flooding with a breach with an external area: https://support.tygron.com/wiki/External_area_(Water_Overlay)
    Since the land is higher than the sea water level in your project, the water flows to the sea.
    To steer the flooding in the land direction, you can use the Breach angle attribute: https://support.tygron.com/wiki/Breach_angle_(Water_Overlay).
    I would also set the Breach width: https://support.tygron.com/wiki/Breach_width_(Water_Overlay)
    You will then see that the flooding also goes in the land direction.

    Related to this topic: are the tides also important for your project? Then we can discuss this further since that is something we are interested in to add to the External area option for example.

  • Hoi,

    Gaat het om een kust zonder zeekering/dijk?

    Groeten Jesse

  • Hoi Jesse,

    Ja inderdaad! heb jij nog tips?

  • Hoi,

    Ik heb daar ook nog geen echt goede oplossing voor. Dit soort kust vragen zijn wij ook al een paar keer tegen gekomen. Je kunt wel proberen door in de zee een kunstmatige kade te leggen met meerdere breaches. Ook hebben we gedacht aan het inzetten van inlets. Voor de toekomst zoek ik meer partijen om samen met TYGRON een getijderand te ontwikkelen die je in de zee te kunnen leggen waarmee je ook stormvloeden kunt simuleren. Ook het weer zakken van het water is van belang.

    Godelief, Maxim had hier ook ideeën bij om dit op te lossen.

    Groeten Jesse

  • Perhaps you can try to model the flooding without a breach, but with at least two water level areas: one for the sea and one for the land. For the sea water level area, choose a water level that is high enough for flooding the land.


    Also thanks for your input Jesse!
