Description: GENESIS calculates shoreline change produced by statial and temporal differences in longshore sand transport produced by breaking waves. The shoreline evolution portion of the numerical modeling system is based on one-line shoreline change theory, which assumes that the beach profile shape remains unchanged, allowing shoreline change to be described uniquely in terms of the translation of a single point (for example, Mean High Water shoreline) on the profile.

The shoreline change model best calculates shoreline movement in transition from one equilibrium state to another. This change is usually caused by a notable pertubation, for example, jetty construction at a harbor or inlet, or placement of beach nourishment material. Key physical parameters & equations: Breaking wave conditions are estimated from input wave information using linear wave theory.
