Abstract
This work is related to jacket-type platform induced local and near-field erosion and deposition processes for different wave and current conditions. The measurement of the scour development over time is achieved by small-footprint echo sounding devices. The final topography of the redistributed sediment in the vicinity of the structure is measured with a 3D laser scanner. The equilibrium scour depth of different wave and current conditions is compared to each other including typical monopile scour developments for reference. Erosion and deposition volumes are computed, which help to understand the sediment entrainment and redistribution around the structure. Differences of erosion volumes of two spacings of structure nodes near to the sea bed are compared for the same hydrodynamic conditions in order to better estimate the implications and magnitudes of structural elements close to the seafloor on the sediment redistribution.
