Use of a Rubble Berm for Reducing Runup, Overtopping, and Damage on a 1V to 2H Riprap Slope. Experimental Model Investigation

Abstract

Laboratory tests with irregular waves to determine wave runup characteristics and armor stability of riprap revetments are discussed. Tests include conventional, plane, 1 on 2 slope revetments, and conventional revetments fronted by rubble berms. Rubble berms tested reduced the maximum runup by rather modest amounts, typically around 10 percent, but produced substantial improvement in the armor stability. These effects are discussed and quantified. This study demonstrates the need for a reliable irregular wave run- up gage for laboratory studies of rough, porous coastal structures Berm, Revetment, Damage, Riprap stability, Overtopping, Runup
