From: Fractal properties of shoreline changes on a storm-exposed island
Wavelet coefficients of shoreline change series for the scale parameter a = 3 and a sketch of the coast. The bottom curve in (a) is based on (b), where the distance from the reference line equals the distance between O and points on the coast line minus the radius of the reference line, R. The position of the reference point, O, is 109.6964°E, 19.3257°N. The adjacent wavelet coefficient series usually present as mirror image of each other, and large amplitudes of these coefficients appear in relatively fixed areas. Arrows within the coefficient curves show the seriously eroded coastal areas after strong storms, which are efficiently recovered afterwards. The map in (b) is generated using ArcMap [10.1] (http://www.esri.com/) and the shoreline is based on the topographic and bathymetric data from GEBCO (http://www.gebco.net/).
