The Hague Municipality, which is responsible for Scheveningen Harbour, is seeking solutions for two problems it is currently facing: reorganization/expansion of Scheveningen Harbour considering the shortage of marina places and the future demands; and connection of the north and south sides of the harbour, namely, bridging De Pijp. CoMEM TU Delft students were retained to provide a solution to these problems, as part of the Multidisciplinary project (CT4061-09) course. This final report covers the full description of the problem and the solutions proposed – a reorganization of Scheveningen Harbour, focused mainly in the Yacht Harbour; the construction of a new marina harbour in De Kom, hereafter called as Scheveningen Fourth Harbour, that includes a new breakwater; and a taxi boat to fulfil the connection demand for the north and south sides of the harbour.
