—Risk studies are very important to avoid human
and economic losses. However the study cost becomes very
expensive in some case when the site scale is very large. That’s
why; using a numerical simulation with a small-scale model is
considered as a suitable solution. In order to have accurate
results on which we can rely to assess the risk, it is necessary to
use sophisticated means to simulate with a high efficiency the
study area. One of the very accurate means able to do that is
based on laser scanning techniques. This article describes how a
3D laser scanning can provide quickly and accurately a 3D
model of the study area reduced model for the risk simulation
step. Moreover, the necessary processing steps in the laser
software named Geomagic v12, are highlighted to achieve a
neat 3-D model. The article also describes the preparation of the
model for the numerical simulation step.
