Application of 3D Laser Scanning Technology in Simulating Dam-Breaking Flood Routing

Abstract

3D laser scanning technology (3D-LST) is a new measuring technology that has been developed rapidly in recent years, which is characterized by obtaining 3D space coordinates of the object surface with its high speed, high accuracy and high density and the object and without contacting with the measured object. It has been increasingly and extensively applied in a variety of fields of engineering. In this paper, the analysis of 3D-LST in the dam-breaking flood routing analysis and its application in emergency rescue has been discussed. And then, a dam breaking and flood routing model has been established through scanning the dam and its downstream terrain with a 3D laser scanner, so as to provide accurate data basis for dam relief and disaster relief.
