Zusammenfassung |
This study focuses on the adoption of a modern, widely-used Terrestrial Laser
Scanner (TLS) application to investigate volcanic rock slopes in Ribeira de
João Gomes valley (Funchal, Madeira island). The TLS data acquisition in
May and December 2008 provided information for a characterization of the
volcanic environment, detailed structural analysis and detection of
potentially unstable rock masses on a slope. Using this information, it was
possible to determine specific parameters for numerical rockfall simulations
such as average block size, shape or potential sources. By including
additional data, such as surface roughness, the results from numerical
rockfall simulations allowed us to classify different hazardous areas based
on run-out distances, frequency of impacts and related kinetic energy.
Afterwards, a monitoring of hazardous areas can be performed in order to
establish a rockfall inventory. |
