Brienz/Brinzauls: Controls on rockfalls in high mountain environments
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. The availability of high temporal and spatial resolution monitoring technologies, most notably terretrial laser scanning (Lidar) and doppler radar, has transformed our ability to understand rockfalls. These systems can be deployed to […]
