Minimal-Resource Computer Program for Automatic Generation of Ocean Wave Ray or Crest Diagrams in Shoaling Waters

摘要

This paper describes an improved computer program for studying linear ocean wave refraction. The program features random-access modular bathymetry data storage. Three bottom topography approximation techniques are available in the program which provide varying degrees of bathymetry data smoothing. Refraction diagrams are generated automatically and can be displayed graphically in three forms: ray patterns with specified uniform deepwater ray density, ray patterns with controlled nearshore ray density, or crest patterns constructed by using a cubic polynomial to approximate crest segments between adjacent rays.
