The tidal coefficient, often denoted as K, quantifies how the amplitude of the tide changes between its extreme spring and neap conditions. Spring tides occur when the Sun and Moon are aligned, producing the greatest tidal range, while neap tides happen when they are at right angles, giving the smallest range.
Because the gravitational forces of the Sun and Moon combine constructively or destructively, the ratio of the spring tide range to the neap tide range is a useful indicator of local coastal dynamics. A higher coefficient means a larger difference between spring and neap tides, which can affect navigation, sediment transport, and coastal flooding risk.
The coefficient is dimension‑less and is calculated directly from observed tidal ranges. It is widely used in tidal prediction models and in the design of marine structures that must accommodate varying water levels.
