SCOURING DUE TO WAVE ACTION AT THE TOE OF PERMEABLE COASTAL STRUCTURES

IN THIS PAPER, THE RELATION BETWEEN A REFLECTION COEFFICIENT OF WAVES AND A VOID RATIO OF PERMEABLE FACE OF A STRUCTURE IS FIRSTLY REVEALED, BECAUSE OF THE FACT THAT THERE IS A CLOSE RELATIONSHIP BETWEEN THE REFLECTION COEFFICIENT & THE PHENOMENA OF SCOURING. BEFORE THE SCOURING DEPTH IS INVESTIGATED, THE RELATION OF THE SCOURING DEPTH TO SUBSIDENCE IS MADE CLEAR. THEN, IT IS FOUND THAT THE SCOURING DEPTH WHICH HAS GREAT INFLUENCE ON SUBSIDENCE OF BLOCKS BECOMES LARGER WITH THE INCREMENT OF THE COEFFICIENT OF REFLECTION. FUTHERMORE, A COMPOSITE CROSS SECTION WHICH HAS AN IMAGINARY UNIFORM SLOPE OF 20 DEGREES IS PROPOSED AS THE STABLE CROSS SECTION AGAINST THE SUBSIDENCE OF BLOCKS. /ASCE/
