Abstract

Securing manoeuverability of a deep draft ship in a sediment loaded tidal river berth O. Stoschek, A. Matheja, C. Zimmermann Franzius-Institute for Hydraulic, Waterways and Coastal Engineering, University of Hannover, Germany Abstract Sedimentation near a deep draft ship berth at a tidal river cannot be avoided due to tidal currents and turbulent processes. But reductions in sedimentation can significantly decrease maintenance dredging costs. Transport and deposition of sediments in a tidal environment depend on factors like sediment size, settling velocity, tides and is controlled by unsteady current velocities and stochastic turbulent processes. A technical solution, minimizing sedimentation near the berth of a deep drafted ship to secure manoeuverability, is presented. The hydrodynamic situation at the tidal part of a river was simulated, using MIKES HD and RMA2 hydrodynamic models. Exchange of sediment-loaded waters entering the berth could be significantly reduced wi
