Note: Value can be positive or negative.
Ocean Tide Amplitude
Ocean Tide Amplitude is the height difference between high and low tides, reflecting gravitational forces from the moon and sun.
Symbol: ao
Measurement: LengthUnit: m
Note: Value can be positive or negative.
Bay Tide Amplitude
Bay Tide Amplitude is the average difference between water levels at high and low tide.
Symbol: aB
Measurement: NAUnit: Unitless
Note: Value can be positive or negative.
Channel Depth
Channel Depth is the vertical distance between the water surface and the lowest point of a waterway or conduit.
Symbol: Dt
Measurement: LengthUnit: m
Note: Value can be positive or negative.
Bank Slope
Bank Slope defined as the angle, measured in degrees of deviation from the horizontal, at which earthy or rock material will stand [length-rise/length-run].
Symbol: m
Measurement: NAUnit: Unitless
Note: Value can be positive or negative.
Channel Width corresponding to Mean Water Depth
Channel Width corresponding to Mean Water Depth is the width of the channel at the water surface level when the water depth is equal to the mean depth of flow.

How to Evaluate Superelevation due to Varying Entrance Channel Cross-Section?

Superelevation due to Varying Entrance Channel Cross-Section evaluator uses Superelevation = Ocean Tide Amplitude*(1-(((Bay Tide Amplitude/Ocean Tide Amplitude)^2)/(4*(Channel Depth/Ocean Tide Amplitude)))-(Ocean Tide Amplitude/(Bank Slope*Channel Width corresponding to Mean Water Depth))*(0.5-(Bay Tide Amplitude/Ocean Tide Amplitude)*cos(Phase Lag)-((3/2)*(Bay Tide Amplitude/Ocean Tide Amplitude)^2)+4*(Channel Depth/Ocean Tide Amplitude)^2)) to evaluate the Superelevation, The Superelevation due to Varying Entrance Channel Cross-Section formula is defined as 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. Superelevation is denoted by S symbol.
