Resumo

The study presents results on the settlement characteristics of rock blocks used in the construction of coastal structures to protect and recover the coast. Bosman et al. (2014) studied the porosity of voids. Packaging density and the associated void porosity are important to coastal engineers for two main reasons. The first is that it affects hydraulic performance. The second is its relation to the acquisition of materials. The biggest question is to define the relation between the volume of the structure and the real value of the porosity, finally defining the relation between the volume of the structure and the weight of the blocks used. This article examines the porosity of voids, containment, and recovery structures on Icaraí beach in Municipality of Caucaia, State of Ceará. The commonly used density value for coastal work payments is 1.62 tons m-3, based on international studies from 28 to 38 years ago. Recent bathymetric surveys at Municipality of Caucaia-CE confirm the actual density value as 1.43 tons m-3.
