Abstract:
This paper presents results from investigations carried out on the hydraulic performance of gabion
structures, with respect to wave energy reflection and transmission processes. The focus of the study
was to investigate the wave reflection and transmission characteristics, which are important in
designing coastal structures with respect to energy dissipation.
The paper presents the results of three hydraulic model investigations on vertical gabion structures.
The experiments were designed to obtain detailed information of transmission and reflection
characteristics of the structures thereby providing a complete profile of wave energy dissipation along
the structures. The experimental programmes were conducted using large physical models to
minimize scale effects. The results are discussed in the context of economical design, improved
hydraulic performance and long term stability.
