DOI: 10.1007/s10346-017-0917-5
Abstract: After the deadly Ms 8.0 Wenchuan earthquake, the Wenjiagou landslide produced steep topography, a narrow gully and abundant loose sediments; these factors have contributed to the high debris flow risk in the Wenjiagou area during… read more here.

DOI: 10.1007/s10346-017-0918-4
Abstract: Mass movements in tropical Pacific small island developing states (SIDS) can be devastating although studies are relatively few and contributing environmental factors are not often investigated in detail. On 25 January 2012, following 3 days of… read more here.

DOI: 10.1007/s10750-018-3534-y
Abstract: Wildfire is one of the most important global agents of disturbance affecting terrestrial and riparian vegetation. Post-fire vegetation changes can alter stream resource pathways and cause channel reorganization and sediment-laden debris flows. Yet, little is… read more here.

DOI: 10.1007/s11629-016-3836-3
Abstract: Infrasonic waves (frequency ≤ 20 Hz) are generated during the formation and movement of debris flows, traveling in air with a speed far higher than that of the debris-flow movement. Infrasound monitoring and localization of… read more here.

DOI: 10.1007/s11629-017-4373-4
Abstract: Flexible net barriers are a new type of effective mitigation measure against debris flows in valleys and can affect the kinematic energy and mass of debris flows. Here, ten flume tests were performed to study… read more here.

DOI: 10.1007/s12517-018-3786-x
Abstract: Because the flexible net barrier is a gradually developed open-type debris-flow counter-measure, there are still uncertainties in its design criterion. By using several small-scale experimental flume model tests, the dynamical evolution properties of debris flows… read more here.
