Hi everybody,
I have a problem that I have not received an answer from anyone for a long time. I want to know what factors affect the zeta parameter?
The next problem is that every time I change the input and header file, the zeta value does not change significantly and I want to know the reason.
Thanks
The image below shows the alignment changes for 20 days from the model output:

Re: zeta calibration
Then, you need to check ROMS governing equations in the WikiROMS or the literature to understand it. I give you a clue: It is a quantity related to the vertically-integrated (barotropic) continuity equation and volume conservation. Does that rings any bells? Are you asking us to explain the basic physics of the ocean?

Re: zeta calibration
Hi Arango, thank you very much for your reply.
Maybe I asked my questions too general and could not make my point.
I do not have any forcing file at the moment and only zeta values are given to the model via TMD in the boundary file. Now that I have been running the model for 30 days but the zeta changes do not seem logical. According to data and other sources, water level changes for the Persian Gulf and the Sea of Oman should be greater than the values shown in the figure.
thanks
