Using 3D Modelling Techniques for Surveys in Two Dimensional Scale Model Tests of Breakwaters

Abstract

This paper focuses on a study of different methodologies for surveying two-dimensional scale models of rubble mound breakwaters.Tests were conducted in one of the LNEC’s irregular wave flumes and involved the use of four different methodologies using photogrammetric and 3D scanning techniques.This paper describes the materials and methods used during the experiments, as well as the results obtained.The data analysis contains the profiles and comparison of the meshes used in each of the techniques, in order to evaluate their application in scale model tests of rubble mound breakwaters. Also, the specific experimental conditions needed for using each of these techniques were investigated.
