Tidal Calculator 0.0.70

This tidal calculator application focuses on both the vertical and horizontal movements of water, serving as a convenient companion to the Admiralty Tide Tables and other publications.

The application facilitates the prediction of tide height at any given moment or identifies the time when the tide reaches a specific level, applicable to both standard and secondary ports, as well as for diurnal and semi-diurnal tides. It provides detailed calculation steps whenever possible, including an analysis based on the rule of twelfths.

With the secondary port tool, users can access robust calculations without the necessity for manual interpolations. Simply input the required data to obtain immediate results.

The tidal stream tool addresses the horizontal movement of water and benefits from a practical interpolation method.

Both the secondary port tool and the tidal stream tool incorporate a harmonic calculation method along with graphical result plotting. This method relies on four principal harmonic constituents, elaborated upon in the app's theory section. These robust features empower users to utilize tidal angles and factors effectively.

Extensive help pages are provided to offer guidance and support, crafted with careful consideration.

The Clearance tool enables users to ascertain the necessary tide height for entering or leaving a port, based on under keel clearance. The vertical method focuses on height calculations derived from a vessel's air draft and can also be employed to determine corrected heights, such as those required for navigating past a lighthouse.

The theory section encompasses critical information about tides, addressing causes and types of tides, as well as the impacts of shallow waters and meteorological factors like wind and barometric pressure.

Additionally, a background section highlights tide predictions using the harmonic constant method, clarifying the four principal constants. A simulation utilizing the Kelvin tidal prediction machine is also included to enhance user understanding and effectiveness in employing these calculators.
