Temperature, snowmelt, and the onset of spring season landslides in the central Rocky Mountains Temperature, snowmelt, and the onset of spring season landslides in the central Rocky Mountains
Snow meltwater (snowmelt) that seeps into the subsurface is a major factor contributing to the development of landslides during the spring in mountainous areas of the Rocky Mountain region. An examination of historical temperature data in relation to spring season landslide occurrences reveals an association between the landslide events and intervals of rising temperatures that...

Hydraulic modeling of unsteady debris-flow surges with solid-fluid interactions Hydraulic modeling of unsteady debris-flow surges with solid-fluid interactions
Interactions of solid and fluid constituents produce the unique style of motion that typifies debris flows. To simulate this motion, a new hydraulic model represents debris flows as deforming masses of granular solids variably liquefied by viscous pore fluid. The momentum equation of the model describes how internal and boundary forces change as coarse-grained surge heads dominated by...

Normalizing rainfall/debris-flow thresholds along the U.S. Pacific coast for long-term variations in precipitation climate Normalizing rainfall/debris-flow thresholds along the U.S. Pacific coast for long-term variations in precipitation climate
Broad-scale variations in long-term precipitation climate may influence rainfall/debris-flow threshold values along the U.S. Pacific coast, where both the mean annual precipitation (MAP) and the number of rainfall days (#RDs) are controlled by topography, distance from the coastline, and geographic latitude. Previous authors have proposed that rainfall thresholds are directly...

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...

Debris-flow hazards in areas affected by the June 27, 1995, storm in Madison County, Virginia Debris-flow hazards in areas affected by the June 27, 1995, storm in Madison County, Virginia
A severe storm on June 27, 1995 triggered hundreds of rock, debris and soil slides from the steep hillsides of Madison County, Virginia. Most of these transformed into debris flows that inundated areas downslope causing damage to structures, roads, utilities, livestock and crops. This report contains an analysis of areas susceptible to debris flows including an examination of source...
