A study on slope instability above Chapman's Peak Drive, Cape Peninsula, South Africa
… unconformity below Chapman's Peak, a suite of slopes that rise directly from the ocean to their summit. A seemingly increased frequency of rockfalls and the death of a young woman in December 1999 led to the closing of the Drive as a public thoroughfare. At the beginning of the year 2000 …

A Comparison of GIS Approaches to Slope Instability Zonation in the Central Blue Ridge Mountains of Virginia
… identify the spatial distributions of relative slope instability. This study presents a systematic evaluation of three common slope instability modeling approaches applied in the Blue Ridge Mountains of Virginia. The modeling approaches include the Qualitative Map Combination, Bivariate …

Analysis of Transient Seepage Through Levees
… with respect to seepage, erosion, piping and slope instability. Transient seepage analyses provide an effective method of evaluating seepage through levees and its potentially destabilizing effects. Floods against levees usually last for days or weeks. In response to a flood, pore pressures …

Spatial Analysis of Soil Creep Rates on Mount Sequoyah, Fayetteville Arkansas
… prone to mass wasting, which is the general downslope movement of sediments, soils, and rock through different processes that cause instabilities along a hillslope, and in its soil and loose rubble mantle. For this study, we looked at soil creep, which is the small-scale movement of soil downhill …

The relationship between slope stability and pore-water pressure in highly plastic clay in the Carrot River Basin
Slope instability in glaciolacustrine clays has been a problem since 1950 at two sites in the Carrot River valley. Movement at the Carrot River and Smoky Burn bridge sites persists, compromising the integrity of the bridge structures. In addition, movement persists along an embankment constructed …

The Mall Bay Formation (Ediacaran) and the Protracted Onset of the Gaskiers Glaciation in Newfoundland, Canada
… Bay Formation is here interpreted as a lower slope to basinal turbidite succession. Dolomitic glendonite occurs throughout the uppermost 550 m of the formation and provides evidence for persistent near-freezing bottom waters. Interpreted iceberg-rafted debris in the form of dispersed outsized …

The Engineering Properties of Glacial Tills in the Taff Valley, South Wales
… and also to delineate areas of past and present slope instability. Qualitative studies using the scanning electron microscope have demonstrated that glacigenic soil types may be genetically differentiated and classified upon the basis of microfabric characteristics.<br/><br/>Laboratory testing …

Seismic analysis of inclined shallow granular deposits
In the last decades many attempts for understanding the cyclic and dynamic behaviour of soft soils have been devoted by the scientific community. The aim of this thesis consists to investigate the mechanical response of two granular material (Hostun and Toyoura sand) in cyclic/dynamic conditions. …

The use of near-surface geophysics for monitoring slopes that affect transport infrastructure
… economic development. To minimise the impact of slope instability on vital transport infrastructure, as well as on terrestrial and aquatic ecosystems, public safety, communities, local heritage, and the economy, and to better inform decision making, there is a need for remote-condition-monitoring …

Slope stability analysis and landslide susceptibility assessment on the SE foot slopes of Mt Cameroon
… and mineralogical characterisation suggests that slope failure within the study area is enhanced by human intervention through anarchical construction and slope undercutting whereas natural slope failure is generated as a result of fracture enhanced permeability. This implies that in the absence …

The influence of the Critical Zone on hillslope hydrology and stability
… of the relationships between the CZ and hillslope hydrology. In this research, the impact of changes in CZ configuration and characteristics on hillslope hydrology and stability is examined in various geomorphological and climatic contexts. The research begins by investigating rainfall …

Delineation of Landslide Hazard and Development of Mitigation Tools in a Vulnerable City
… for the characterization and monitoring of slope stability. Landslides have affected several properties and destroyed infrastructure. Slope failure commonly occurs during heavy rainfall events when slow-moving retrogressive slides transition into earthflows and mudflows. In this study, …

Analysis of flood hazard under consideration of dike breaches
… failure mechanisms: overtopping, piping and slope instability caused by the seepage flow through the dike core (micro-instability). The 2D storage cell model driven by the breach outflow boundary conditions computes an extended spectrum of flood intensity indicators such as water depth, flow …

Combined finite-discrete element modelling of key instabilities which characterise deep-seated landslides from massive rock slope failure
The expression “landslide from massive rock slope failure” (MRSF) is used to indicate large-scale landslides characterised by a variety of complex initial failure processes and unpredictable postfailure behaviour. In this context, deep-seated landslides are classified as “landslides from massive …

THERMO-HYDRO-MECHANICAL NUMERICAL MODELLING TO ASSESS THE ROLE OF CLIMATIC FACTORS IN THE STABILITY OF ALPINE ROCK SLOPES
… impacts on the stress-strain evolution of rock slopes, through the adoption of a multi-disciplinary approach and the development of multiphysics numerical analyses. Several case studies of past and active rockslide events in the Alpine region were analyzed, for which the effects of different …

Geophysical models of Mount Etna, Sicily : its structural evolution and implications for slope stability
… in the modern volcanic edifice with its observed slope instability and region of past collapse (the Valle del Bove). The structure and evolution of the volcano and, more importantly, the Valle del Bove are poorly understood but have major effects on its present day behaviour. Several geophysical …

Late Pleistocene-Holocene sedimentary processes at the active margin of South-Central Chile : marine and lacustrine sediment records as archives of tectonics and climate variability
… and therewith the stability of the continental slope: more stable slope conditions during interglacial periods entail lower turbidite frequencies than in glacial periods. Since glacial turbidite recurrence times are congruent with earthquake recurrence times derived from the historical record …
