The Continued Development of the Third-generation Shallow Water Wave Model "SWAN"

This report briefly describes the development of the SWAN model compared to the previous authorized version, SWAN 40.01. The most recent version of SWAN, SWAN 40.11 Cycle III was released on the 26th of October 2000.

A short overview of reflection formulations and suggestions for implementation in SWAN

The reflection implemented in SWAN version 40.11 is just specular reflection. It gives the mirror image of the action density spectrum, cutting it off for all directions that are not directed towards the obstacle and multiplying it by the reflection factor C_r^2 (square because the reflection factor is w.r.t. wave height). To improve the...
