Abstract

This article presents a simple analytical method giving estimates of wave-driven bottom stresses for very rough and mud seabeds in shallow water from long-term wave statistics in deep water. The results are exemplified using long-term in situ wave statistics from the Northern North Sea and by providing examples representing realistic field conditions. The results can be used to make estimates of the seabed shear stress in estuarine and coastal waters based on, for example, global wave statistics.
