Once segmentation of 3D surface data of a rock pile has been performed, the next task is to determine the visibility of the surface rocks. A region boundary-following algorithm that accommodates irregularly spaced 3D coordinate data is presented for determining this visibility. We examine 3D surface segmentations of laboratory rock piles and determine which regions in the segmentation correspon...

Debris flows in the Wudongde dam area, China could pose a huge threat to the running of the power station. Therefore, it is of great significance to carry out a susceptibility analysis for this area. This paper presents an application of the rock engineering system and fuzzy C-means algorithm (RES_FCM) for debris flow susceptibility assessment. The watershed of the Jinsha River close to the Wud...

ABSTRACTCurrently, the number of damaged watersheds has not improved, as evidenced by increasing incidence natural disasters such landslides, floods and droughts. Much work been done to restore watershed, but no significant results have achieved. This type research is quantitative descriptive using geographic information system (GIS) software analysis program, in form overlay analysis, factors ...

Abstract This research describes a quantitative, rapid, and low-cost methodology for debris flow susceptibility evaluation at the basin scale using open-access data geodatabases. The proposed approach can aid decision makers in land management territorial planning, by first screening areas with higher susceptibility. Five environmental predisposing factors, namely, bedrock lithology, fracture n...

1. introduction mountain regions are increasingly endangered by a variety of disaster, including avalanche, debris flows, and rock slide. some characteristics such as elevation, angle of slope, vegetation and climatic elements could affect the avalanche event. indeed, avalanche is the second factor in soil erosion that causes demolition; therefore, it threatens the food safety. iran has two mai...

Abstract The main purpose of the present study is to develop a debris flow susceptibility map mountain area (Susa Valley, Western Italian Alps) by using an upgraded version Bonetto et al. ( Journal Mountain Science 18, 2021) approach based on Rock Engineering System (RES) method. In particular, under investigation was discretized in 5 × 5-m grid which GIS-based analyses were performed. Starting...
