Abstract

The paper concerns the reflection performance of so-called 'sponge' layers, which are used to model partially reflecting (porous) structures in a numerical model domain. Various compositions of sponge layers and their performance with respect to wave reflection, main direction of propagation, and directional spreading have been investigated. The numerical model used in this study was a finite difference model based on the time-dependent mild-slope equation. Comparisons are made with reflection measured in physical experiments with short-crested waves. The results obtained so far indicate that in several cases partial reflection of short crested waves can be described satisfactorily in numerical models by use of sponge layers.
