Redistribution of Basal Forces and Shielding Model for Seismic Signals of Debris Flows Over Loose Thin‐Layer Sediments

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Debris flows over riverbeds generate intense basal force fluctuations that radiate seismic signals, offering a key tool for remotely monitoring their dynamics. In steep, highly erosive mountainous channels, bedrock is often covered by a thin layer of loose sediments, which significantly reduce seismic energy.
