AbstractA model is presented for predicting the behaviour of waves in a harbour of constant depth with reflecting walls made up of rectangular segments. Each convex corner of the harbour wall is treated as a source of diffracted waves, of strengths linearly related to the local incident wave field. A representation of these diffracted waves as superpositions of decaying sinusoidal waves is obtained. Within the harbour waves are propagated according to a parabolic finite difference equation, and the system may be solved within a fixed number of iterations proportional to the number of corners. The method is applied to some simple harbour geometries, with satisfactory results.
