Frequency–Volume Relation and Prediction of Rainfall-Induced Landslides
Engineering Geology, 2001Abstract Rainfall-induced landslides constitute a major public concern in Hong Kong. This paper investigates two aspects of critical importance to landslide hazard and risk assessment and management: magnitude–cumulative frequency relationship for landslides, and relationship between rainfall and the occurrence of landslides.

Precipitation transformation in rainfall-induced landslide forecasting
2010 18th International Conference on Geoinformatics, 2010Precipitation is an important meteorological element widely used in rainfall-induced landslide forecasting. Most existing studies on rainfall-induced landslide forecasting focus on the determination of forecasting models and parameters. Five transformation methods of precipitation are evaluated in this paper to improve the forecasting models through a ...

Boundary effects of rainfall-induced landslides
Computers and Geotechnics, 2014In the study of landslides, it is generally assumed that an impermeable boundary exists at a certain depth and failure occurs at this boundary. In reality this is not always the case and failures can occur at any depth. This paper aims to study the effect of boundary conditions on landslides, using a series of seepage and stability analyses performed ...

Controlling parameters for rainfall-induced landslides
Computers and Geotechnics, 2002Slope instability due to rainfall is a common geotechnical problem in tropical and subtropical areas. The numerical analysis of this problem requires the definition of various hydrological characteristics of the soil in addition to the climatic information.

Uncertainties in rainfall-induced landslide hazard
Quarterly Journal of Engineering Geology and Hydrogeology, 2002The paper addresses the main uncertainties associated with the occurrence of rainfall induced landslides. Spatial variability of site conditions, local geology and rainfall contributes significantly to the uncertainty of landslide hazard. Urban landslide problems require the management of slopes of marginal stability.

Stability Analyses of Rainfall Induced Landslides
Journal of Geotechnical and Geoenvironmental Engineering, 2004The slope stability issues concerning rainfall induced slope failures are investigated and presented. Specifically, the effect of both negative and positive pore water pressures on the stability of initially unsaturated slopes are carefully explained and coupled with infinite slope analysis methods in order to present a predictive formulation of slope ...

Modeling of Rainfall-Induced Shallow Landslides of the Flow-Type
Journal of Geotechnical and Geoenvironmental Engineering, 2010The paper deals with the modeling of failure and postfailure stage of shallow landslides of the flow-type that often affect natural shallow deposits of colluvial, weathered, and pyroclastic origin. The failure stage is frequently associated to rainfall that directly infiltrates the slope surface and to spring from the underlying bedrock.

Briefing: Rainfall-induced landslides in Singapore
Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2001Minor, shallow landslides have occurred frequently on the island of Singapore. However, very few major landslides (greater than 10 m in height) have occurred. Slope failures in the sedimentary Jurong and granitic Bukit Timah formations have occurred largely on slopes with angles greater than or equal to 27°.

An integrated model for predicting rainfall-induced landslides
Geomorphology, 2009This study proposes a novel method that combines a deterministic slope stability model and a statistical model for predicting rainfall-induced landslides. The method first uses the deterministic model to derive the rainfall rate critical to induce slope failure for each land unit.

SUSCEPTIBILITY MODELLING OF RAINFALL INDUCED LANDSLIDES
2013Occurrence of rainfall induced landslides coincides in time with the period of high persistence of heavy wet spells and in spatial locations where vegetative cover has been denuded. As the rain water percolates into the slope it increases the soil water content and reduces in situ suction, followed by built-up of pore water pressures resulting in a ...
