The fact that landslides constitute more than a local hazard is now well recognized and has been responsible for numerous major investigations by the U.S. Geological Survey and other organizations. This volume, approached from the engineering geology standpoint, has two goals: (1) to update significant information about landslides and present some case histories and (2) to refocus earlier works into new syntheses and insights. Includes contributions not only from the authors but also from government agencies, universities, and consulting firms. Presented in 5 parts: 1. Overview; 2. Regional Studies; 3. Specific and Local Studies; 4. Engineering Geology and Highway Engineering; and 5. Environmental Planning. A valuable resource book if you are involved with studies of landslides.
Relationship between morphology, hydrology, geotechnics, and vegetation on an old northern Ohio landslide
Published:January 01, 1977
The geotechnics, hydrology, morphology, and vegetation of an ancient but active landslide in the lower Cuyahoga River valley, Ohio, were studied to define mechanisms contributing to failure of the slope. Engineering laboratory tests of soils showed them to be heavily overconsolidated and prone to erosion. Hydrology of the slope was monitored by periodically measuring water levels in piezometers and wells. Fluctuations in water elevations and hydraulic gradients during the observation period were correlated with precipitation data and with effective stresses. The morphology of the slope was defined in terms of recent and relict activity and was related to the vegetation and hydrology. The results of this study indicate that an interrelationship exists between the morphology, hydrology, and vegetation of the slope. Continued slope failure is caused by the unstable nature of soils and the abundance of water entering the flow system of the slope.
