Check dams are one of the structures used to control debris flows. In this study, in order to evaluate the effect of hydraulic parameters on debris sediment trapping rate by the slit trapezoidal check dams with different angles, and to develop an empirical relation for determination of trapping coefficient of the dam reservoirs, three physical models of the check dams were used. The tests were ...

Snowmelt-triggered debris flows commonly occur in mountains. On 14 June 2019, a flow occurred on steep, east-facing slope composed of unconsolidated glacial and periglacial sediments Yosemite National Park. Originating as shallow landslide, ~1,300m 3 ripe snow was instantaneously entrained into the carrying boulders, trees, soil downslope. The forested area at toe strained out leaving muddy slu...

Debris-flow activity is expected to change in a future climate. In this study we connect susceptibility model for debris-flows on regional scale with climate projections until 2100. We use assess changes of hydro-meteorological trigger conditions debris flows six regions the Austrian Alps. find limited an annual basis, but distinct when separating between types and regions. While east south Aus...

Recent natural disasters, such as the 2004 Indian Ocean and 2011 Tohoku Tsunami, exhibited the importance of tsunami-resistant infrastructure in high-risk coastal areas. The failure of critical infrastructure in tsunami-stricken communities has led to a recent emphasis on extreme loading conditions associated with tsunami events. One of the critical loads identified by previous research was deb...

Landslide occurrence in the Salmon Arm and Vernon forest districts in the last five years has stimulated research to determine how small drainage basins might be classified into debris flow prone, debris flood prone, or flood prone. Alluvial fans situated at the base of several entrenched stream systems may have people dwelling on them. In addition to safety concerns, water quality and habitat ...

A catastrophic storm that struck the central Virginia Blue Ridge Mountains in June 1995 delivered over 775 mm (30.5 in) of rain in 16 h. The deluge triggered more than 1000 slope failures; and stream channels and debris fans were deeply incised, exposing the stratigraphy of earlier mass movement and fluvial deposits. The synthesis of data obtained from detailed pollen studies and 39 radiometric...

Debris flows are among the most dangerous and destructive natural hazards that affect human life, buildings, and infrastructures. Worldwide, these phenomena claim hundreds of lives and millions of dollars in property losses every year. Starting from the ’70s significant scientific and engineering advances in the understanding of the processes and in the recognition of debris flow potential have...
