Breaching flow occurs during the breach development of the embankment, dike, earthen dam, landslide barrier, etc. and plays an import role in the breaching erosion as the driving force.
[Case 4] During the rainy season in this region, flooding rivers and landslides create barriers to access.
Due to the mountainous landscape, low economic development, and poor infrastructure, Wenchuan County and its surrounding regions are extremely vulnerable to earthquakes and secondary disasters such as landslides and barrier lake floods.
Seismic risk assessment of the earthquake's main shock combined with secondary disasters, especially due to large-scale landslides, and barrier lake formation and collapse, is important in the evaluation of earthquake losses.
Using LiDAR from the Oregon Coast Range, we found gentler channel gradients, wider valleys, lower gradient hillslopes, and less shallow landslide potential in an above-barrier catchment compared to a neighboring catchment devoid of persistent knickpoints.
Temporary barriers caused by large landslides affect salmon throughout the Pacific Northwest, especially when they persist for decades or more and impede migration into major river basins (O'Connor 2004; Table 1A).
More than 300 people in a highway in Tibet were trapped last month when a landslide blocked a river and formed a barrier lake 150m long and 30m deep, China's official news agency Xinhua reported.
The isolation of portions of many valleys such as those of the Rheinwald, Poschiavo, and Urseren by barriers of resistant rock or by prehistoric landslides was an impetus to the formation of communes and of the early Alpine cooperatives.
A barrier lake, formed by fallen rocks and a landslide after a huge earthquake, threatened the lives and properties of thousands of people both upstream and downstream.
After the roars in the Moscone Center had subsided and a fitful general election campaign had run its course, hopes for Mr. Mondale and his plain-speaking, barrier-breaking running mate were buried in a Reagan landslide.
