Functions Used

sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)
cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)

Variables Used

Ocean Tide Amplitude - (Measured in Meter) - Ocean Tide Amplitude is the height difference between high and low tides, reflecting gravitational forces from the moon and sun.
Bay Superelevation - (Measured in Meter) - Bay Superelevation means that the average level of the bay is greater than the average elevation of the ocean over a given time period.
Duration of Inflow - (Measured in Second) - Duration of Inflow is the period over which a stream or river carries a consistent flow of water into a system.
Tidal Period - (Measured in Second) - Tidal Period is the time it takes for a specific site on Earth to rotate from an exact point under moon to same point under moon, also known as “tidal day” and it’s slightly longer than a solar day.

STEP 1: Convert Input(s) to Base Unit

Bay Superelevation: 4.51 Meter --> 4.51 Meter No Conversion Required
Duration of Inflow: 1.2 Hour --> 4320 Second (Check conversion here)
Tidal Period: 130 Second --> 130 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

a_o = Δ_BS/(sin(2*pi*t/T)/(1-cos(2*pi*t/T))) --> 4.51/(sin(2*pi*4320/130)/(1-cos(2*pi*4320/130)))

Evaluating ... ...

a_o = 3.99551134833178

STEP 3: Convert Result to Output's Unit

3.99551134833178 Meter --> No Conversion Required

FINAL ANSWER

3.99551134833178 ≈ 3.995511 Meter <-- Ocean Tide Amplitude

What is Bay Superelevation?

A Superelevation of the bay means that the average level of the bay is greater than the average elevation of the ocean over a given time period. An obvious cause of this effect is the introduction of freshwater into the bay from local rivers and streams. The effect of long-term (months or years) rises in sea level causing a long-term rise in bay level is not included in this definition of bay superelevation, since both sea and bay are responding simultaneously. The bay may not rise at the same rate as the sea due to possible circulation effects if multiple inlets connect the bay to the ocean.

What is Ocean Dynamics & Ocean Tide?

Ocean dynamics define and describe the motion of water within the oceans. Ocean temperature and motion fields can be separated into three distinct layers: mixed (surface) layer, upper ocean (above the thermocline), and deep ocean. Ocean dynamics have traditionally been investigated by sampling from instruments in situ.
Tides are caused by the gravitational pull of the moon and the sun. Tides are very long-period waves that move through the oceans in response to the forces exerted by the moon and sun. Tides originate in the oceans and progress toward the coastlines where they appear as the regular rise and fall of the sea surface.

How to Calculate Tidal Amplitude in Ocean?

Tidal Amplitude in Ocean calculator uses Ocean Tide Amplitude = Bay Superelevation/(sin(2*pi*Duration of Inflow/Tidal Period)/(1-cos(2*pi*Duration of Inflow/Tidal Period))) to calculate the Ocean Tide Amplitude, The Tidal Amplitude in Ocean formula is defined as the elevation of tidal high water above mean sea level.
