Hydraulic Resistance of Artificial Concrete Blocks

open access: yesCoastal Engineering 1970, 1970
Theoretical analysis and experiments are made to clarify the mechanism of reducing the wave energy by the block structures In order to express the hydraulic reistance of three different kinds of blocks, three different models are proposed The hydraulic radius and the porosity of the block structures are essentially important factors m the expression of
