Overview of Large Catastrophic Landslides | U.S. Geological Survey
2018年7月2日 · Ongoing research aims to improve understanding of factors and mechanisms that control the locations, timing, extent, and speed of large, potentially catastrophic landslides. Although they are relatively uncommon, large catastrophic landslides move rapidly destroying everything in their paths.
Landscape reaction, response, and recovery following the catastrophic …
2014年5月23日 · Granular landscape surfaces react to pulsed changes in fluid flow conditions through erosion and deposition, recovering during interevent periods over timescales commensurate with the physiohydraulic conditions of a given landscape. The routing of future catastrophic floods and their geomorphic effectiveness [Wolman and Gerson, 1978] will ...
"Catastrophic Landscape Modification from Massive Landslide Tsunamis…
Extensive modifications observed and documented on several low gradient fan deltas within the fiord make Taan Fiord an excellent laboratory for characterizing geomorphic signatures of a high runup tsunami event.
Catastrophic landscape modification from a massive landslide …
2019年12月28日 · Documented geomorphic modifications of several low gradient fan deltas within Taan Fiord make it an excellent laboratory for characterizing signatures of a landslide tsunami event.
Catastrophic landscape modification from a massive landslide …
2020年3月15日 · Large landslide tsunamis have greater potential for local geomorphic modification. The October 17th, 2015 Taan Fiord landslide and tsunami generated a runup of 193 m, nearly an order of magnitude greater than most previously surveyed tsunamis.
Legacies of catastrophic rock slope failures in mountain landscapes
2008年2月1日 · This review examines interpretive issues relating to catastrophic, long-runout landslides in the context of large numbers of recently discovered late Quaternary events. It links relevant research in landslide science, including some novel or hitherto-ignored complexities in the nature and role of these events, to broader concerns of mountain ...
Migration and transformation of coastal wetlands in response to …
2022年6月29日 · The risk of catastrophic, landscape-scale wetland loss is especially high along the Gulf of Mexico and south Atlantic coasts, with hot spots in the Mississippi River Delta, Everglades, Albemarle-Pamlico, and Chesapeake Bay estuaries.
Catastrophic landscape modification from a massive landslide …
2020年3月15日 · Vegetation loss and tsunami return-flow channels serve as decades long evidence of high run-up. Large landslide tsunamis have greater potential for local geomorphic modification. The October 17th, 2015 Taan Fiord landslide and tsunami generated a runup of 193 m, nearly an order of magnitude greater than most previously surveyed tsunamis.
The role of catastrophic geomorphic events in central …
Evaluation of the role of catastrophic events in landscape evolution includes assessment of their contributions to denudation and formation of prominent landscape features, and how they vary through space and time.
Evaluating Landscape Change Following Catastrophic Fires in
The western U.S., including California, has experienced extreme weather events that have resulted in catastrophic and deadly fires. These destructive fires have resulted in loss of life and property, and burned through iconic landscapes within the National Park Service (NPS).
