Abstract
Sand waves superimposed on sand banks may vary in morphology due to variations in local conditions. Apart from scientific reasons to understand the processes controlling sand wave shapes, these variations are also relevant to safe navigation and offshore engineering projects. Previous research reported variations in sand wave shape and migration over sand banks based on local observations. However, quantification of shape variations for all individual sand waves in a sand wave field remains to be investigated. In this study we present a 2D approach to analyse sand wave height and asymmetry. It is applied to two study sites in the North Sea where sand waves are superimposed on sand banks. The results show that the sand wave heights only vary over sand banks at one of the locations and that asymmetry varies in magnitude and direction at these sites.
