Tidel
Tidel is a provisional term used in coastal science to describe a dimensionless index that characterizes the effectiveness of tidal forcing at a given location. It summarizes how a site responds to the tidal cycle by combining information about tidal amplitude, timing, and waveform shape with local bathymetry and shoreline geometry.
Etymology and scope: The term blends tidal and level and was proposed in the early 2020s as
Definition and components: A tidel consists of three components: amplitude ratio (R), phase lag (P), and waveform
Calculation and measurement: Data from long-term water level sensors, tidal constituents, and shoreline orientation are used.
Applications and limitations: Tidels have been used to compare tidal energy potential, inform flood risk assessments,
