Abstract

So far a great number of scientific literature in field of geomorphology is published which deals with sand ripples, especially wave ripples, formed under oscillatory flow. The present work is a review of scientific literature on evolution of wave induced sand ripples. Principles of ripples formation and behavior in changing conditions, as well as classification, migration mechanisms and geometry features have been considered. Oscillatory motion which is responsible for generation of considered formation is explained.
The thesis is aimed to make a theoretical basis for practical work of Ulrich Floth, PhD student in University of Rostock, a long term observations of evolution and migration of ripples over several months period in the coastal area of Baltic Sea by means of a customized underwater stereo-photogrammetric camera system.
