Questions tagged [tides]

Tides are the periodic fall and rise of sea-level due to gravitational forces of the moon, sun or earth-rotation. When asking questions specifically about tides, use this tag and also include the [ocean], [moon], [sun] or [earth-rotation] tag if appropriate.

Is it possible to know the tides of a particular location 50 years or 100 years from now?

Assuming no change in sea level (for the sake of argument), is it possible to know the high and low tides a half century or more in the future? Is information like this available to the general ...

Why is the tidal range at the entrance to the bay of fundy so high?

This question is a continuation of my previous question: Questions about the validity of a certain model for tidal resonance at the Bay of Fundy. I need to answer this question in order to return to ...

Simple numerical model of tide with an elliptic scheme

I have recently been given the task of developping a coastal model for tides. I have a few requirements, it must not be time stepping in order to be as fast as possible and in finite differences ...

Presence of cross stratified conglomerates in fan deltas

Why are cross stratified conglomerates found in deposits of fan deltas? I know that fan deltas are alluvial fans that deposit directly into the sea, hence they are poorly sorted.But could not ...

How to de-tide a daily averaged sea level data?

Coud you help me to resolve this situation? : I have a raw daily averaged sea level time series, as you know when we perform a harmonic analysis (e.g. using T_Tide from MATLAB) we need to put our data ...

Do tidal forces affect subduction?

I know subduction in plate tectonics is mainly density driven. Probably a hypothetical question, but can weaknesses caused by tidal forces have an influence on the start of a subduction zone? Would ...

How do I determine the phase lag for a tide

I want to determine the height of a sine wave for some tidal constituents for which I would use the following equation: π‘Œ(𝑑)=𝐻cos⁑(πœ”π‘‘βˆ’πœ™), where H is the amplitude, πœ” is the speed of rotation, t ...

Questions about the validity of a certain model for tidal resonance at the Bay of Fundy

I'm currently working on a (relatively-simple) fluid-dynamics model of the tidal resonance at the Bay of Fundy, a place which is known for his world-breaking tidal range (15 meters on average, while ...

were can I find the Greenwich equilibrium argument for tidal prediction(Vo+u)?

the closest i've got was with a table in the following manual that only went up to the year 2000. https://tidesandcurrents.noaa.gov/publications/SpecialPubNo98.pdf

Velocity boundary conditions from water depth time series

Currently, I am setting up a hydrodynamic model for a coastal zone. For this purpose I need to impose the velocity and water level at the open boundary. Tidal models (e.g. TPXO) can give both velocity ...

Phase of S2 constituent in tidal prediction

I ran the ETERNA code for the prediction of tidal gravity at some station. Then I use Fourier analysis to recover the amplitude and phase of the S2 constituent. As I understand, the phase of the S2 ...

Reason behind diurnal tides

I know that an area has a diurnal tidal cycle if it experiences one high and one low tide every lunar day. Many areas in the Gulf of Mexico experience these types of tides. I read that: Diurnal tides ...

Topography and flash flooding

I'm looking for a study or document showing the effect of the topography, slopes, the sea level and the tide on flash flooding occurrence. Thanks in advance
