Abstract
Compliant, fluid-like mud is a highly dissipative subaqueous medium that absorbs wave energy in the coastal and lacustrine environments, and in turn contributes to water column turbidity. The wave-mud interaction process characteristically causes an oscillatory motion of the surficial mud layer, which thereby influences benthic processes associated with bottom stability and nutrient and contaminant fluxes across the mudwater interface. Physical principles underlying the response of the wave-mud system with reference to water wave attenuation, mud motion and interfacial erosion are examined. Simple hydrodynamic models, which account for the rheological constitutive properties of mud and sediment dynamics in the water column, are shown to simulate prototype observations to an acceptable degree of accuracy. Such models also provide a basis for designing underwater mud berms that absorb wave energy and thereby mitigate wave impacts.
