Tsunami modelling by TUNAMI N2 in Mirone?

[Zuhair Ezan]

Hi everyone,

Could you please provide me information how to do Tsunami modelling by TUNAMI N2 or TINTOL? I have prepared initial deformation condition for TINTOL but I am not getting what to do with maregraph option?

Thanks in advance.

[Joaquim Luis]

Zuhair,

I have not yet written any tutorial to use TINTOL (other codesm swan and tsun2 are now deprecated) but made all possible so that the use is as intuitive as it can. Namely, hovering the mouse over the buttons show helping tooltips. For example what you ask says:

"Check this if you want to compute water height at maregraphs"

and the edit button reads:

"Name of the file with the maregraph locations"

So,

1 - Using this is optional

2 - to use it provide a file with the x y coordinates of each virtual  tide gauge you want. Not mentioned, but you can add a third column with the tide gauge name

Hope it helps

Joaquim Luis

You can't. I have removed that option some versions ago (don't remember exactly when). It was  old stuff and was not transmitting the momentum in the borders.

Thank you so much for response.

It is showing only SWAN and TINTOL in 'Tsunami' option of Mirone I have downloaded. Could you please tell me where can I get tsun2 in Mirone?

Thank you in advance.

Thank you again.

I have done Tsunami modelling with SWAN but I am not getting how to know about the wave height or run up at any specific point along the coast?

Is it done by 'Exact Profile' option in 'Tools' after getting propogation model? (see attachment). Is that the wave height in meters along X-axis?

Thank you in advance.

[Joaquim Luis]

I mentioned before that SWAN is deprecated (and I don't use it for years). Although it can do a good job for propagation, it's inundation capabilities are very weak. The modelling code in TINTOL (NSWING) is far better. 

Anyway, in any case what one get after a run are the frames of the water height at selected instants. This can be either grids that represent the situation for the whole region, or virtual maregraphs for selected points in function of time.

Yes, you can do profile extraction in particular time frames or, the best, select the 3D netcdf output and load it in the "Aquamoto" tool for posterior analysis.

Please, keep posting to the mailing list

You must be suffering from some connecting issue. That is a old version. After updating it should say 2.7.0dev in the title bar and

I checked, it is mentioning that 'this mirone version is updated to latest'. (see attachment)

I tried with stand-alone and it is showing some error (see attachment).

Thanks for helping me a lot.

Do one thing. Use the stand-alone version instead or otherwise learn how to update the matlab version using Github (and even than, there might e issues with compiled, e.g. mex, files.). The thing is that I have fixed many things since the 2.6 release and those are very easy to update  on the standalone version (just do, "Help -> Chaeck for updates") but more complex with the source code version.

Also, pick a time step close to the suggested one but as round as possible. For example 5.25 in your case.

Thank you so much for bearing my questions.

I am facing difficulties in modelling via TINTOL, I selected initial deformation .grd file for 'source' option (see attachment), but I am not getting the output grids as I got in case of Swan. Where I am making error? 

Thank you in advance.

[Joaquim Luis]

Again, please  keep posting to the mailing list and to me personally.

What date does the "Help -> About" reports?

It has been updated now, there was some problem with internet. But, still TINTOL showing the same error. Where I am doing error? (see attachment)

I just tried one example here and it worked fine, which means you are not running an updated version.

[Meriem Amine]

Hello everybody 
I wish to make a modelling of a tsunami in the coastal zone of a city in Morocco (within the framework of my project of thesis). I installed the Mirone software and I realized a grid of bathymetry .Grid but I do not manage to find the approach to make the modelling of the tsunami. Could you, please, guide me on this approach and which are the parameters which I shall need?
Thank you in advance for your help which would be so precious to me.

How do we actually model tsunami using mirone? This is for my MTech project work.

[Mr patel vikram]

According to me mirone is not a good option to model a tsunami waves

What have you tried so far?

Thank you.. do you have an idea regarding which simulator will be good for this.

[Priyanka Kumar]

Till now i have been trying to write a code to solve the shallow water equations in matlab.

[Joaquim Luis]

Sorry, don't understand the question. Choosing among which simulators. Regarding Mirone only TINTOL is recommended.

[Joaquim Luis]

Till now i have been trying to write a code to solve the shallow water equations in matlab.

That's a lot more complicated than trying to use TINTOL without a manual. Modeling with nested grids is something more difficult to find by oneself (i.e. without help from me) but single layer it should be trivial to find how it works. Ofc it helps one when know what we are trying to do. Basicaly, one only need an initial deformation grid (time zero condition) and a bathymetry file. Both grids must be exactly compatible as with any other modeling program.

[Joaquim Luis]

OK, I have added a small tutorial on how to do tsunami propagation. See

http://w3.ualg.pt/%7Ejluis/mirone/howtos/A_simple_tsunami_propagation_example.pdf

[Priyanka Kumar]

Thank you so much for the tutorial

[Priyanka Kumar]

Can I know by which method is the Shallow Water Equation(SWE)  solved in Mirone? As I am writing my own code, a very simple one to just solve SWEs

[Joaquim Manuel Freire Luís]

Mirone uses NSWING that is a finite differences model. Is this what you are asking?

[Priyanka Kumar]

I mean the method, finite difference is used just to discretize the equation and any other numerical method is applied thereafter.

[Joaquim Manuel Freire Luís]

Then I’m afraid I don’t understand the question. But notice that NSWING is open source. The code is in the Mirone repository in GitHub.
