WAVE PRESSURE DISTRIBUTION ON PERMEABLE VERTICAL WALLS

Hendrik Bergmann, Hocine Oumeraci

Abstract


The pressure distribution at permeable vertical walls is investigated within a comprehensive large-scale test programme considering experiments with a variation of wave parameters and structure porosities. Monochromatic non breaking and slightly breaking waves on such structures are examined and results are compared to the GODA formula for impermeable vertical walls and a modified GODA method which has been developed here for permeable walls. Two parameters involving the structure porosity are introduced to account for the nonlinear processes at permeable walls. Using these parameters new prediction formulae have been derived for the pressure distribution at the wall.
