Drone LiDAR surveys of abandoned roads reveal long-term debris-flow hazards

A research team led by University of Tsukuba has developed a new method to estimate long-term debris supply from steep slopes by measuring debris accumulated on decades-old abandoned roads. Debris supplied by rockfall and related slope processes is a key factor controlling the frequency and magnitude of debris flows. However, estimating the amount of debris supplied over several decades has been technically challenging.
