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.

Hydrodynamic characteristics of vertical slotted wall breakwaters
Author :
The present paper investigates the hydrodynamic performance characteristics of a vertical slotted wall, which is used as a breakwater to protect harbours and coastalareas. The breakwater model consists of a vertical slotted wall with an impermeable upper and lower part where the draft is a decimal multiple of the total depth. The middle part is permeable with a porosity of 50%. For regular waves, a numerical model has been developed using the Eigenfunction expansion method and the boundary condition at the breakwater with the objective to compute wave transmission, reflection and energy dissipation coefficients. Laboratory experiments are conducted for various values of structural parameters and wave periods. The numerical results are compared with experimental studies and found to be in good agreement.
