Landslide risk assessment and management: an overview
Landslides can result in enormous casualties and huge economic losses in mountainous regions. In order to mitigate landslide hazard effectively, new methodologies are required to develop a better understanding of landslide hazard and to make rational decisions on the allocation of funds for management of landslide risk. Recent advances in risk analysis and risk assessment are beginning to provi...
متن کاملOverview of Geology , Hydrology , Geomorphology , and Sediment Budget of the Deschutes River Basin , Oregon Jim
Within the Deschutes River basin of central Oregon, the geology, hydrology, and physiography influence geomoqhic and ecologic processes at a variety of temporal and spatial scales. Hydrologic and physiographic characteristics of the basin are related to underlying geologic materials. In the southwestern part of the basin, Quaternary volcanism and tectonism has created basin fills and covered an...
متن کاملA State of Art on Airborne Lidar Application in Hydrology and Oceanography: a Comprehensive Overview
Nowadays, lidar has been accepted as one of the important sensors providing accurate and dense 3D point cloud from earth surface terrain and water bathymetry. The basic idea of using lidar stems from the problem of measuring water depth without direct contacting with the water body or without any instrument mounted on the water surface in shallow regions. Bathymetric lidar that uses two differe...

The aim of this contribution is to give an overview of recent developments in the use of Geographical Information Systems and Earth Observation which have been applied for improved landslide inventory mapping, landslide susceptibility and hazard assessment, elements at risk mapping, and finally landslide vulnerability and risk assessment. Geo-Information science and earth observation consists o...
متن کاملRemote Sensing for Landslide Investigations: An Overview of Recent Achievements and Perspectives
Landslides represent major natural hazards, which cause every year significant loss of lives and damages to buildings, properties and lifelines. In the last decades, a significant increase in landslide frequency took place, in concomitance to climate change and the expansion of urbanized areas. Remote sensing techniques represent a powerful tool for landslide investigation: applications are tra...
