IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

MODELING OF WAVE ATTENUATION BY VEGETATION WITH XBEACH

Over the past decades the effect of vegetation (e.g. kelp, mangroves, sea grass) on nearshore coastal processes has received more and more attention. In recent years several numerical wave models have been extended to include this effect. In the current study, the numerical storm impact model XBeach is extended with formulations for damping of short waves, infragravity waves, and mean flow. The model is verified using a number of laboratory test cases. XBeach is found to be able to reproduce the damping effect of vegetation on waves well, even though the amount of calibration done was limited. This work is considered as a first step only, and further model developments regarding vegetation implementation in XBeach are foreseen for the near future. Eventually, XBeach should be able to accurately take into account the effect of relatively complex vegetation species (e.g. mangroves) on the nearshore hydro- and morphodynamics in a computationally efficient way.
