The lunar theory of tides can not predict anomalously high tides in the Fundy Bay, which depend on the current velocity in the north of the Gulf of Maine.

[Colin2B]

Correctly!
The height of the tides is now about 2 meters.

That doesn’t make sense. You said “To calculate the height of the tides of the Bay of Fundy, you need to know the speed of flow in the north of the Gulf of Maine, .........To create tides 18 meters high, the speed of the current should be about 15 km / h.”

I tell you the current is 2km/h. 2 ≠15.
Show your calculations so we can understand what you are saying, otherwise it sounds as though you are just making it all up. If you show your calculations I will tell you the depth underneath the 2km/h current.

The lunar theory of tides can not predict anomalously high tides in the Fundy Bay, which depend on the current velocity in the north of the Gulf of Maine.

I’m sorry to disappoint you, but it does.
The largest tidal range offshore of Fundy is about 1.5m with a period, predicted by the lunar theory, of 12 hours and 26 minutes.

Liquid in any basin has a characteristic period of oscillation and, once set in motion, the liquid will rhythmically slosh back and forth in this time period.  The speed at which it oscillates depends on the length and depth of the basin. Due to the enormous size, the unique funnel shape, and the immense depth of the  Bay of Fundy, its natural period of oscillation is somewhere between 12 and 13 hours. That oscillation is in perfect sync with the Atlantic ocean tide flooding into the bay every 12 hours and 26 minutes, which results in resonance and the extreme tides within the bay, it has nothing to do with the speed of the current in the Gulf of Maine.

The bay’s shape and bottom topography also have a secondary influence on the tides. The bay is shaped like a large natural funnel; it becomes narrower and shallower towards the upper part of the bay, forcing the water higher up onto the shores.

Again, it has nothing to do with the speed of the current in the Gulf of Maine.

Tides and ebbs are formed not along the entire coast of the seas and oceans, but only in those coasts where the high angular velocity of the currents (1-5 km / h).
On the rectilinear coasts, where currents do not have angular velocity, tides and ebbs do not form.
With an increase in the angular velocity of the current in the north of the Sea of ​​Okhotsk (10 km / h), the height of the tides in the Penzhina Bay increases to 12 meters.

With an increase in the angular velocity of the current in the north of the Gulf of Maine (15 km / h), the height of the tides in the Bay of Fundy rises to 18 meters.

"Record high tide in the Bay of Fundy - 21.6 meters - occurred only once in the history of observations, on the night of October 4 to October 5 in 1869 under the influence of the cyclone Saxby Gale."
On the night of October 4 to 5, in 1869, under the influence of the cyclone Saxby Gale, "a record rainfall fell over the river basins flowing into the Bay of Fundy (300 mm in one day), so that the waters of the Bay of Fundy poured into the Gulf of Maine and increased the speed of rotation a whirlpool in the Gulf of Maine.
http://www.gulfofmaine.org/ebm/toolkitsurvey/images/exec-sum-2.jpg
Cyclone Saxby Gale rotating counter-clockwise, also contributed to the unraveling of the whirlpool.
In an abnormally cold winter and during a drought, when rivers flowing into the Bay of Fundy merge, the height of the tides does not exceed 1 meter.
https://www.tide-forecast.com/locations/Fundy-Offshore-1-Nova-Scotia/tides/latest
The average flow velocity in the north of the Maine Bay is about 2 km / h, due to which the height of the tides in the Bay of Fundy is about 2 meters.
To create tides 18 meters high, the current speed should increase to 18 km / h.

The flow velocity range in the north of the Maine Bay is from 2 to 18 km / h

"Why are the Bay of Fundy Tides the Highest?
The average tidal range of all oceans around the globe is 1 meter (3ft), so how can the tidal difference in the Bay of Fundy reach up to 16 meters? This tidal phenomenon exists because the bay has a few distinct features: a substantial amount of water and a unique shape and size that causes resonance."

Do you know what resonance is?

[Yusup Hizirov (OP)]

Resonance of water in the Gulf of Maine, must be accompanied by a swing of water to the south and north, who saw it?
Who is the author of the theory of resonances (Such names as Laplace, Darwin, Erie and others, declined to comment on the tides in the bays).
In the lunar theory of tides about resonance nothing is written.

You have obviously never sailed have you? I have and the lunar theory of tides allows:
a) prediction of tide height many years in advance so we predict accurately what clearance there is under the boat so can work out at what time on a specific day we can enter a port with depth restrictions such as a sandbar.
b) Tidal flow direction at a specific point
c) Velocity of tidal flow at a specific point.
Items b and c mean that we can plot a course over ground taking into account tidal effects using information from almanacs (i.e. books) that you are so dismissive of. Your disdain for books (aka the printed word) reminds me of the attitude of TheBox, flat earthers  and other anti-science cranks. You ideas are similarly nonsensical and pointless.

Can someone summarise what tidal resonance theory is?

Utterly ERRONEOUS.
Our planet and its satellite are a "dancing" couple: both have circular movements around their common center of mass, absolutely necessary to maintain them without falling on each other, of some 28 days period ...
That has nothing to do with much faster daily spinning of Earth, as far as causes are concerned !!

Not really. Poetry is poetry, don't take it to heart.

The Earth spins and has a fluid environment, 2/3rds of the planets surface if not more, water.

I think the idea is one of how the relationship of a planet spinning with a 2/3rds liquid surface being gravitationally attracted to a satellite/Moon is the issue, right?

The ocean is still a Ballerina.

Oscillations work well in flat planes, but on massive spinning objects such as the planet Earth, its a different game right?

If you're talking about a spinning object, spinning stably on a point, we're looking at a ballerina, right?


Putting this in the context of a 2/3rds liquid surface planet, what are those liquid arms doing with the gravitational pull of the Moon to stay stable?

A flywheel, a counterweight, that other tide facing away from the Moon, right?

You asked about resonance theory of tides. These are local effects for which one example is given in the post I quoted. The Bay of Fundy is a small area on the earth’s surface and to all reasonable approximations that area of the earth’s surface can be considered flat.
The post explains the resonance in the bay.

What @rmolnav is pointing out is that the spin of the earth is not part of the modern barycentric model of lunar tides.

[opportunity]

And the modern barycentric model of lunar tides doesn't account for "two tides", tides on opposing positions of the planet?

It wouldn’t be a valid theory of tides if it didn’t, you might want to look at this https://www.thenakedscientists.com/forum/index.php?topic=49715.0
But bear in mind that you only get 2 tides on opposite sides in the idealised situation of a planet with no land masses. Once you get land masses you get local effects like resonance, funneling, double tides etc.

[opportunity]

Do you think your "resonance" idea is going to catch?

It's a great way to stimulate debate, don't get me wrong there.

The Mystery of High Tides

No mysticism - everything is natural. The secret of the tidal wave lies in the gigantic volume of water and the characteristic form in the form of a pipe, looking upwards inclined. Also, the period of water fluctuation in the Fundy coincides with the period of water fluctuation in the ocean. In miniature this can be imagined as follows. If you move your hands back and forth in the bathroom with water, you can create a mini-tsunami effortlessly and in seconds. The tidal wave is formed by a similar principle. We add that the period of water fluctuations in the bay (12-13 hours) coincides with the period of water oscillation in the ocean (12 hours 26 minutes). Therefore, the tidal wave is repeatedly amplified by fluctuations in oceanic waters. If we return to the example with the bathroom, imagine that the second person added efforts to create a mini-tsunami. And what will the effect be? The wave will rise higher, because the force of influence has increased.

So the science says, and the indigenous people, the Indians of the Mikmak tribe, have a different opinion on this matter. They believed that the tidal wave is caused by a giant whale that lives at the bottom of the bay and beats its tail. This legend has a well-grounded basis: whales often swim to a deep gulf (its depth is up to 214 m).
