Landslide Hazard Automated Zonation (LHAZ) system
The degree of hazard due to landslide in any region is difficult to assess manually. An automated system having capability to correlate causes contributing automated landslide hazard is expected to be an efficient alternative. The objective of this paper is to explain LHAZ (Landslide Hazard Automated Zonation) system, an automated system that has been developed to determine the intensity and ex...
متن کاملFuzzy Approach to Landslide Susceptibility Zonation
The paper addresses a landslide-prone area on Fruška Gora Mt. in NW Serbia. It proposes a model of relative landslide susceptibility based on fuzzy sets. Having a variety of spatial attributes (proven statistically significant) at disposal, as well as present landslide inventory map, we conducted systematic analysis through (i) assigning fuzzy memberships to attribute categories, and (ii) combi...
متن کاملLandslide Hazard Zonation Using Quantitative Methods in GIS
Landslides are major natural hazards which not only result in the loss of human life but also cause economic burden on the society. Therefore, it is essential to develop suitable models to evaluate the susceptibility of slope failures and their zonations. This paper scientifically assesses various methods of landslide susceptibility zonation in GIS environment. A comparative study of Weights of...
متن کاملArtificial neural networks and cluster analysis in landslide susceptibility zonation
A landslide susceptibility analysis is performed by means of Artificial Neural Network (ANN) and Cluster Analysis (CA). This kind of analysis is aimed at using ANNs to model the complex non linear relationships between mass movements and conditioning factors for susceptibility zonation, in order to identify unstable areas. The proposed method adopts CA to improve the selection of training, vali...
متن کاملLandslide hazard assessment: recent trends and techniques
Landslide hazard assessment is an important step towards landslide hazard and risk management. There are several methods of Landslide Hazard Zonation (LHZ) viz. heuristic, semi quantitative, quantitative, probabilistic and multi-criteria decision making process. However, no one method is accepted universally for effective assessment of landslide hazards. In recent years, several attempts have b...
