Summary

This chapter covers basic concepts on the forces that drive tides. It presents a description of the main harmonics or constituents related to the driving forces, followed by a presentation of the concept of spring and neap tides, as well as their analogous tropic and equatorial tides. It then introduces the fundamental physics for a frictionless tidal wave, while depicting progressive and standing waves. It continues with the conditions for tidal resonance. The chapter then includes the effects of bottom friction on tidal currents and covers the effects of convergent coastlines by presenting the concepts of hypersynchronic, hyposynchronic, and synchronic basins. It follows with the effects of Earth’s rotation on frictionless tides and the generation of amphidromic points. The chapter goes further with an exploration of the effects of lateral bathymetry on tidal flows.
