GASAKe:forecasting landslide activations by a genetic-algorithms-based hydrological model
GASAKe forecasting landslide activations genetic-algorithms hydrological model
2015/8/6
GASAKe is a new hydrological model aimed at forecasting the triggering of landslides. The model is based on genetic algorithms and allows one to obtain thresholds for the prediction of slope failures ...
Improving predictive power of physically based rainfall-induced shallow landslide models: a probabilistic approach
Distributed model prediction shallow landslide expand the space geotechnical engineering the model of the rainfall infiltration
2014/12/18
Distributed models to forecast the spatial and temporal occurrence of rainfall-induced shallow landslides are based on deterministic laws. These models extend spatially the static stability models ado...
Geophysical and Geotechnical Investigations of a Landslide in Kekem Area, Western Cameroon
Landslide Resistivity Argillaceous Material Basal Undercutting Kekem Cameroon
2013/3/11
Geophysical and geotechnical surveys were conducted in the Western Cameroon (Kekem area) following a landslide on argillaceous material in order to understand the triggering processes and mechanisms o...
Landslide damage assessment using the Support Analysis Framework (SAF): the 2009 landsliding event in Calabria (Italy)
Landslide damage assessment Support Analysis Framework the 2009 landsliding event in Calabria
2010/9/10
In this paper, a simplified methodological approach is used to assess damage indices related to landslide phenomena that occurred in Calabria (Italy) between November 2008 and January 2009. This appro...
Evaluation of a preliminary satellite-based landslide hazard algorithm using global landslide inventories
preliminary satellite-based landslide hazard algorithm global landslide inventories
2009/12/16
Most landslide hazard assessment algorithms in common use are applied to small regions, where high-resolution, in situ, observables are available. A preliminary global landslide hazard algorithm has b...
Combining historical and geological data for the assessment of the landslide hazard:a case study from Campania,Italy
historical and geological data assessment landslide hazard
2009/12/11
Past slope instabilities at Quindici (one of the five towns of Campania that was hit by catastrophic landslides on 5 May 1998) and in the Lauro Valley are investigated to improve the understanding of ...
Landslide tsunami case studies using a Boussinesq model and a fully nonlinear tsunami generation model
Landslide tsunami case studies a Boussinesq model a fully nonlinear tsunami generation model
2009/12/10
Case studies of landslide tsunamis require integration of marine geology data and interpretations into numerical simulations of tsunami attack. Many landslide tsunami generation and propagation models...
Observation of surface features on an active landslide, and implications for understanding its history of movement
surface features an active landslide history of movement
2009/12/10
Surface features are produced as a result of internal deformation of active landslides, and are continuously created and destroyed by the movement. Observation of their presence and distribution, and ...
Landslide susceptibility assessment considering landslide typology. A case study in the area north of Lisbon (Portugal)
Landslide susceptibility assessment landslide typology the area north of Lisbon (Portugal)
2009/12/9
The aim of the study is to confirm the importance of discriminate different types of slope movements for a better landslide susceptibility evaluation. The study was applied to the sample area of Calha...
A geomorphological approach to the estimation of landslide hazards and risks in Umbria, Central Italy
a geomorphological approach landslide hazards and risks Umbria, Central Italy
2009/12/9
We present a geomorphological method to evaluate landslide hazard and risk. The method is based on the recognition of existing and past landslides, on the scrutiny of the local geological and morpholo...
Impact of mapping errors on the reliability of landslide hazard maps
mapping errors landslide hazard maps
2009/12/9
Identification and mapping of landslide deposits are an intrinsically difficult and subjective operation that requires a great effort to minimise the inherent uncertainty. For the Staffora Basin, whic...
Flow-type failures in fine-grained soils:an important aspect in landslide hazard analysis
Flow-type failures fine-grained soils important aspect landslide hazard analysis
2009/12/8
Forecasting the possibility of flow-type failures within a slow-moving landslide mass is rarely taken into account in quantitative hazard assessments. Therefore, this paper focuses on the potential tr...
A methodological approach to characterise Landslide Periods based on historical series of rainfall and landslide damage
methodological approach Landslide Periods historical series landslide damage
2009/12/8
Landslide Periods (LPs) are defined as periods, shorter than a hydrological year, during which one or more landslide damage events occur in one or more sectors of a study area. In this work, we presen...
On the influence of temporal change on the validity of landslide susceptibility maps
temporal change validity landslide susceptibility maps
2009/12/8
The consideration of non-stationary landslide causal factors in statistical landslide susceptibility assessments is still problematic. The latter may lead to erroneous model predictions, especially in...
A web-based GIS for managing and assessing landslide data for the town of Peace River,Canada
web-based GIS managing and assessing landslide data town of Peace River
2009/12/8
Assessment of geological hazards in urban areas must integrate geospatial and temporal data, such as complex geology, highly irregular ground surface, fluctuations in pore-water pressure, surface disp...
