Abstract:
This paper presents an innovative use of a light detection and ranging (LiDAR) system for stability investigation and reporting required by authorities for the Alfsee reservoir, Germany. That report has to provide updates on the stability of the dam structure of the flood control reservoir. Air-borne drones and terrestrial vehicles equipped with optical sensor systems are used to provide geo-referenced point data as a base for a digital model of the terrain. By using this information, it is easily and quickly possible to generate sections of the dam structure and reservoir for the analyses. Slope stability analyses can then be performed more precisely and rapidly than by relying on information from conventional measurements.
