Cell-DEVS formalism extends cellular automata modeling. In this paper, we present a simple model for landslides using a model of a sand pile. The model uses Cell-DEVS formalism and CD++ tool to model and simulate landslides. Using this simple model, we present how Cell-DEVS formalism can be used to model systems that involve material accumulation and flow. Material flow and accumulation need sp...

The landslides cause several casualties and economic losses all over the world. Studies show that most casualties happen within the first 18-35 minutes after the burial. This demands life-detecting systems to be available immediately on the spot after the disaster. A suggested approach is deploying multiple units of these instruments across the country. Main constraint in developing countries f...

The growing availability of digital topographic data and the increased reliability of precipitation forecasts invite modelling efforts to predict the timing and location of shallow landslides in hilly and mountainous areas in order to reduce risk to an ever-expanding human population. Here, we exploit a rare data set to develop and test such a model. In a 1·7 km catchment a near-annual aerial p...

The paper describes first the theoretical framework of a “single layer” three phase material. The formulation is general and particular cases are dry and fully saturated soils. The formulation and discretization of the motion and balance equations is presented. Two constitutive equations are used in the applications described: A brittle model for saturated soils and a Mohr-Coulomb elastoplastic...

Information on landslide displacement from SAR Interferometric Point Target Analysis (IPTA) and sketch maps from aerial photography interpretation are combined for the study of landslides in Ticino, Southern Switzerland. Numerous unstable phenomena are considered in this mountainous region, with an elevation range from approximately 200 m a.s.l. to more than 3000 m a.s.l. The results achieved w...

Synthetic Aperture Radar Interferometry (InSAR) is an established method for the detection and monitoring of earth surface processes. This approach has been most successful where the observed area fulfills specific requirements, such as sufficient backscattering, flat slope gradients or very slow changes of vegetation. We investigated the capability of two different InSAR techniques and achieve...

abstract recognition of effective factors on landslide occurrence and so high and low hazard region is one of the most important and necessary works for mitigation of landslide damages. in this study, from all of the effective factors on landslide occurrence, land use changes and road construction, into a parts of tadjan watershed with area about 708.08 square kilometers in south of sari, was s...

Some landslides move imperceptibly downslope, whereas others accelerate catastrophically. Experimental landslides triggered by rising pore water pressure moved at sharply contrasting rates due to small differences in initial porosity. Wet sandy soil with porosity of about 0.5 contracted during slope failure, partially liquefied, and accelerated within 1 second to speeds over 1 meter per second....
