IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Numerical simulation of 2dh wave propagation over submerged permeable breakwaters with steep slopes
Author : ANASTASIOS S. METALLINOS (1) & CONSTANTINE D. MEMOS (2)
ABSTRACT
The applicability of a 2DH Boussinesq-type wave model in simulating wave propagation over submerged breakwaters with
steep slopes was investigated. The original fully dispersive and highly nonlinear model of Chondros and Memos (2014),
able to simulate wave propagation over impermeable bottom profile practically in any water depth was extended to cover
2DH wave propagation over permeable structures with steep slopes. This extension was attained by coupling the main
solver with a nonlinear Darcy-Forchheimer resistance equation. Computed results were compared against experimental
surface elevation measurements including regular cases and Jonswap 3D spectra. Data were taken from experiments in a
wave basin of Aalborg University, Denmark, provided by Zanuttigh and Lamberti (2003) as part of the European Research
project DELOS. The layout, considered in this paper, was composed by two collinear detached porous breakwaters
forming a gap between them. The modified model was able to accurately capture the nonlinear phenomena due to wave
propagation over submerged porous structures, including the higher harmonics that appear in the downslope of the
inclined breakwaters. The numerical simulations when compared with measurements showed very good agreement in
most cases.
