Abstract

The paper deals with a mathematical method to calculate wave heights in harbours caused by diffraction and reflection. Using the complete SOMMERFELD-solution for a semi-infinite breakwater, a linear superposition method is applied. The reflections of the harbour boundary are taken into account using a geometric mirroring principle. The computer-programme allows the phase-correct superposition of any number of wave systems and, therefore, also the consideration of re-reflections which can be important in the presence of vertical walls. For the presentation of results (K'-lines) an interpolation-plot-programme is used. The computer-programme has been applied to the harbour Greenville extension (Liberia) (BURKHARDT, 1977). Hydraulic model tests were performed to check the programmes, especially with respect to the influence of harbour reflections and the layout of the breakwater head.
