OESbathy version 1.0:a method for reconstructing ocean bathymetry with generalized continental shelf-slope-rise structures
OESbathy version 1.0 ocean bathymetry continental shelf-slope-rise structures
2015/9/10
We present a method for reconstructing global ocean bathymetry that combines a standard plate cooling model for the oceanic lithosphere based on the age of the oceanic crust, global oceanic sediment t...
The Influence of Earthquakes on Open-Pit Slope Stability
Earthquakes Open-Pit Slope Stability Safety Factor Pseudostatic Approach
2013/3/11
Estimation of stability of natural slopes, embankments, dams and open-pit slopes during earthquakes are complex and non-linear problems, therefore physical modeling is used for decision of it. As a re...
Optimal Scale Selection for DEM Based Slope Segmentation in the Loess Plateau
Optimal Scale Multiresolution Slope Segmentation Loess Plateau
2013/3/7
Optimal scale selection is the key step of the slope segmentation. Taking three geomorphological units in different parts of the loess as test areas and 5 m-resolution DEMs as original test date, this...
Influence of weathering and pre-existing large scale fractures on gravitational slope failure: insights from 3-D physical modelling
weathering and pre-existing large scale fractures gravitational slope failure 3-D physical modelling
2009/12/14
The shallower one represents the zone subject to homogeneous weathering and is made of low strength material of compressive strength σl. The deeper (core) part of the model is stronger and simulates i...
Slope stability monitoring from microseismic field using polarization methodology
Slope stability microseismic field polarization methodology
2009/12/10
Numerical simulation of seismoacoustic emission (SAE) associated with fracturing in zones of shear stress concentration shows that SAE signals are polarized along the stress direction. The proposed po...

rock slope stability shallow landslide susceptibility assessment Jasmund cliff area
2009/12/8
In this contribution we evaluated both the structurally-controlled failure susceptibility of the fractured Cretaceous chalk rocks and the topographically-controlled shallow landslide susceptibility of...
Identification of active release planes using ground-based differential InSAR at the Randa rock slope instability, Switzerland
active release planes ground-based differential InSAR the Randa rock slope
2009/12/31
Five ground-based differential interferometric synthetic aperture radar (GB-DInSAR) surveys were conducted between 2005 and 2007 at the rock slope instability at Randa, Switzerland. Resultant displace...
Rock-slope failures in Norway;type,geometry,deformation mechanisms and stability
Rock-slope failures type geometry deformation mechanisms stability
2009/12/3
Extensive studies of Norwegian rock-slope failure areas support a subdivision into three principle types: (1) Rockfall areas, (2) rockslide areas, and (3) complex fields. The classification is based o...
