Nodes are points at which the displacement of oscillating water surface is always zero, while the amplitude of oscillations in antinodes is maximum. Both features result from the superposition of two or more progressive waves propagating in opposite directions in a body of water. Quasinodes and antinodes appear in partially reflected waves. If a rectangular basin oscillates in both its longitudinal and transverse directions, there appear nodal and antinodal lines where m and n are integers of possible values of 0, 1, 2 ... defining the modes of longitudinal and transverse oscillations, respectively (m = O and n = O for the first harmonics, i.e., fundamental modes, and so on). Nodes and antinodes can also be found in many other forms of water motion, as in tides. Standing edge waves (q.v.) provide a satisfactory explanation for the formation of crescentic bars (in regions of small tidal range) according to Bowen and Inman 1971). By analogy, the nodal point of coastal sediment...
