Predicting landslide vegetation in patches on landscape gradients in Puerto Rico Predicting landslide vegetation in patches on landscape gradients in Puerto Rico
We explored the predictive value of common landscape characteristics for landslide vegetative stages in the Luquillo Experimental Forest of Puerto Rico using four different analyses. Maximum likelihood logistic regression showed that aspect, age, and substrate type could be used to predict vegetative structural stage. In addition it showed that the structural complexity of the vegetation...

Debris-flow mobilization from landslides Debris-flow mobilization from landslides
Field observations, laboratory experiments, and theoretical analyses indicate that landslides mobilize to form debris flows by three processes: (a) widespread Coulomb failure within a sloping soil, rock, or sediment mass, (b) partial or complete liquefaction of the mass by high pore-fluid pressures, and (c) conversion of landslide translational energy to internal vibrational energy (i.e...

Regional landslide-hazard evaluation using landslide slopes, Western Wasatch County, Utah Regional landslide-hazard evaluation using landslide slopes, Western Wasatch County, Utah
Landsliding has historically been one of the most damaging geologic hazards in western Wasatch County, Utah. Accordingly, we mapped and analyzed landslides (slumps and debris slides) in the area to provide an empirical basis for regional landslide-hazard evaluation. The 336 landslides in the 250-sq-mi (650-km2) area involve 20 geologic units, including Mississippian- to Quaternary-aged...

Depositional processes in large-scale debris-flow experiments Depositional processes in large-scale debris-flow experiments
This study examines the depositional process and characteristics of deposits of large‐scale experimental debris flows (to 15 m3) composed of mixtures of gravel (to 32 mm), sand, and mud. The experiments were performed using a 95‐m‐long, 2‐m‐wide debris‐flow flume that slopes 31°. Following release, experimental debris flows invariably developed numerous shallow (∼ 10 cm deep) surges...

Debris-flow initiation experiments using diverse hydrologic triggers Debris-flow initiation experiments using diverse hydrologic triggers
Controlled debris-flow initiation experiments focused on three hydrologic conditions that can trigger slope failure: localized ground-water inflow; prolonged moderate-intensity rainfall; and high-intensity rainfall. Detailed monitoring of slope hydrology and deformation provided exceptionally complete data on conditions preceding and accompanying slope failure and debris-flow...
