Tidal simulation with transient boundary (water surface elevation)?
 
Hello All,


I'm trying to create a simulation of coastal flooding from tide-like events.


The model setup should be a transient boundary condition,
where one wall of the model has an inlet water surface that corresponds to a water surface elevation.


The water surface elevation data is from a NOAA tide buoy and provides water surface elevation in in feet in 6 minute intervals.


Are there any tide or flood models that have a transient boundary condition that I could reference?


I'm not sure how to set this up with U and alpha.

Hi David,

Have you found an answer to your problem?

Thank you in advance

No, I never found any examples. Here is a jupyter notebook that I created for opening a HEC-RAS file and converting the data into time-varying boundary conditions that are saved as alpha.water and U files for different timesteps. This j-notebook answers part of my question but doesn't represent a complete project that uses this information.

Thank you so much for sharing.
I am seeking a way to set time series of water surface elevation as a boundary condition.
Any suggestions from others would be appreciated.
