COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus. Debris Flow Hazards in the United States Republished from United States Geological Survey Fact Sheet Debris flow in Oregon: This debris flow occurred in the Columbia River gorge near the town of Dodson, Oregon, during a rainfall and snowmelt event in February (Photo Inset: S. Cannon, USGS). Year Published: THRESH—Software for tracking rainfall thresholds for landslide and debris-flow occurrence, user manual. Precipitation thresholds are used in many areas to provide early warning of precipitation-induced landslides and debris flows, and the software distribution THRESH is designed for automated tracking of precipitation, including precipitation forecasts, relative to. The largest subaerial (on land) landslide in Earth's recorded history was connected with the eruption of Mount St. Helens volcano in Washington state, USA. That landslide had a volume of cubic kilometers ( cubic miles) of material and the landslide traveled about kilometers (14 miles) down the North Fork Toutle River.

Long-term records of the magnitude and frequency of debris flows on fans are rare, but such records provide critical information needed for debris-flow hazard and risk assessments. This study explores the history of debris flows on a fan with seasonally inhabited cabins at Pope Creek along the Entiat River about 48 km upstream from the town of Entiat, : Jeffrey A. Coe, Erin Bessette-Kirton, Stephen Slaughter, Francis K. Rengers, Trevor A. Contreras, Ka. These proceedings contain papers presented at the Fourth International Conference on Debris-Flow Hazards Mitigation: Mechanics, Prediction, and Assessment held in Chengdu, China, September , The papers cover a wide range of topics on debris-flow science and engineering, including the factors triggering debris flows, geomorphic effects, mechanics of debris flows (e.g., rheology. Debris-Flow Hazards Mitigation: Mechanics, Prediction, and Assessment. This proceedings, Debris-Flow Hazards Mitigation: Mechanics, Prediction, and Assessment, contains papers presented at the First International Conference held in San Francisco, California, August , The papers covered a variety of topics ranging from debris-flow mechanics to debris-flow hazards Cited by: Debris Flow Hazards and Related Phenomena is set to become the standard reference on debris flows, debris avalanches and related editors provide a complete treatment of all aspects of debris flow and debris avalanche research whilst making the book .

Emergency Assessment of Post-Fire Debris-Flow Hazards The maps below depict the likelihood of debris-flow generation and estimates of flow magnitude in locations where debris flows initiate. The models do not predict downstream impacts, potential debris-flow runout paths, and the areal extent of debris-flow or flood inundation. Debris flows are accelerated downhill by gravity and tend to follow steep mountain channels that debouche onto alluvial fans or front, or 'head' of a debris-flow surge often contains an abundance of coarse material such as boulders and logs that impart a great deal of ng behind the high-friction flow head is a lower-friction, mostly liquefied flow body that. In China, there are ab debris flow sites distributed over approximately 45% of the territory area, where more than towns suffer from debris flow disasters, and to people are. The U.S. Geological Survey conducts post-fire debris-flow hazard assessments for many major fires across the Western United States. The information from these assessments is provided in an interactive map, allowing users to view fires by location or name and access detailed maps of debris-flow probability in the area affected by each can select fires by year back to
