How to consider sea level rise escenarios with Delft3D Flow?

Padawan Posts: 25 Join Date: 4/6/17 Recent Posts
Hi, I want to use Delft3D to simulate different escenarios of sea level rise in an estuary.

In a previous work I simulated water levels in a time series format using for the open boundary tide gauge measurements for two different periods of time of the year. Now I would like to use the same input data to simulate different sea level rise escenarios (Since I do not have tidal constituents). Is there a way to incorporate a sea level rise rate in the model?

Thank you in advance for your help.

Hi Esther,

I have had a go at this in the past and simply added a uniform sea-level rise value to all of my tide gauge measurements used to force water level at the boundary. I wanted to look at changes in water level by 2100 under different IPCC sea-level rise predictions, so just added 0.72 m and 0.98 m to all of the values in the .bct files. I am unaware of a more dynamic option than that in Delft!

Hope that helps, 

Charlotte

Dear Charlotte

Thank you, I also has same idea. However, I still doubt about it due to i don't find that method in some references such in SCI paper/journal. 

Do you have some references to support your method/idea? Let me know if you have it. 

 

Thank you in advance

Meddy

I have used this article to reference adding incremental sea-level rise projections to a boundary condition: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0117030

This paper used this method to simulate flood inundation using LISFLOOD. I hope that helps!
