Vågdämpning i bestånd av vass (Phragmites australis) / Wave attenuation in stands of common reed (Phragmites australis)
Common reed is found in near-shore areas of many European lakes, where it frequently forms dense stands. In order to evaluate the effects of common reed stands on waves and to test a model for wave attenuation caused by vegetation, a field experiment was conducted in the common reed stands of a southern Swedish lake. The water surface displacement was measured simultaneously both within and outside these stands. According to the wave measurements, the significant wave height decreased within the stands of common reed, while the average period seemed to increase. The model was adjusted to the prevailing wave regime with the drag coefficient, which seemed to depend on Reynolds number.
