Abstract
Sediment transport on natural beach profiles can be described in different ways, with respect to the spatial complexity and temporal variability of morphodynamic processes. The different transport phenomena display the results of the intensity of hydrodynamic processes acting along the beach profile. Field measurements indicate clearly that under storm conditions the suspended load dominates the total sediment t~ansport, while under moderate wave conditons its contribution to the total transport decreases. Komar (1998) gives some examples on the relation of the two transport phenomena. The aim of this paper is to describe these transport phenomena qualitatively and quantitatively with the help of large wave flume tests which have been conducted within the MAST-Ill SAFE project (Harem, 1998) in the 'Grosset Wellenkanal' (GWK) in Hannover. INTRODUCTION Coastal beach profiles are subjected to a continous adaption to forcing wave and water level conditions which result in the spatial complexity and temporal variability of hydrodynamic processes. Under moderate everyday hydraulic conditions (low wave energy) and storm surges (high wave energy) hydrodynamic processes are responsible for different morphodynamic processes and resulting beach profile changes. It is not unusual that morphological changes of the beach profile withixt a temporally limited storm surge cause more erosion than the profile changes caused by the wave climate over a whole year. Hydroand morphodynamic processes are in close relation to morphological and sedimentological conditions along the beach profile. In order to give a qualitativ and quantitative description of the ongoing processes the sandy beach profile has to be 1) Coastal Engineer, Zum Breen 17, 26180 Rastede, Germany, e-maih k.peters@tu-bs.de 2) Coastal Engineer, Rebenring 20, 38106 Braunschweig, Germany, e-maih j.newe@tu-bs.de 3) Professor, Dept. of Hydrodynamics and Coastal Engineering, Leichtweiss-lnstitute, Tech.
