This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of landslide inventories is the basis for quantitative hazard assessment. Landslide inventory maps are prepared using conventional methods (field surveys, visual interpretation of aerial photographs) and new remote sensing techniques. One of the most promising techniques for landslide detection and mapping is related to the measurement of the ground deformation by satellite radar interferometry (InSAR).This doctoral thesis is dedicated to the preparation of a multi-date inventory, from multi-source data, including InSAR, for a quantitative assessment of landslide hazard. The methods associate the analysis of Earth Observation products and statistical modelling for the characterization of landslide hazard in a rural and mountainous region of the South French Alps. They have been developed at the slope (1:5000-1:2000) and the regional (1:25.000-1:10.000) scales. For the creation of a multi-date inventory, this study developed a combined interpretation of time series of SAR images, aerial photographs, geomorphological maps, historical reports and field surveys. At the slope-scale, a geomorphologically-guided methodology using InSAR was proposed to identify landslide displacement patterns and measure their kinematic evolution. At regional scale, spatio-temporal distribution of landslides is characterised and hazard is assessed by computing spatial and temporal probabilities of occurrence for a given intensity of the phenomena. The spatial occurrence is evaluated using a multivariate model (logistic regression). The temporal occurrence of landslide is estimated with a Poisson probability model to compute exceedance probabilities for several return periods. Different mapping units were used in the modelling, and their influence on the results is discussed. Analysis of landslide hazard is then proposed for some particular hotspots. Relationships between landslide (re)activations and triggering factors are envisaged.
Download or read book Object Based Image Analysis written by Thomas Blaschke and published by Springer Science & Business Media. This book was released on 2008-08-09 with total page 804 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a collection of invited interdisciplinary persp- tives on the recent topic of Object-based Image Analysis (OBIA). Its c- st tent is based on select papers from the 1 OBIA International Conference held in Salzburg in July 2006, and is enriched by several invited chapters. All submissions have passed through a blind peer-review process resulting in what we believe is a timely volume of the highest scientific, theoretical and technical standards. The concept of OBIA first gained widespread interest within the GIScience (Geographic Information Science) community circa 2000, with the advent of the first commercial software for what was then termed ‘obje- oriented image analysis’. However, it is widely agreed that OBIA builds on older segmentation, edge-detection and classification concepts that have been used in remote sensing image analysis for several decades. Nevert- less, its emergence has provided a new critical bridge to spatial concepts applied in multiscale landscape analysis, Geographic Information Systems (GIS) and the synergy between image-objects and their radiometric char- teristics and analyses in Earth Observation data (EO).

Experience, Theory and Practice contains the invited lectures and all papers presented at the 12th International Symposium on Landslides, (Naples, Italy, 12-19 June 2016). The book aims to emphasize the relationship between landslides and other natural hazards. Hence, three of the main sessions focus on Volcanic-induced landslides, Earthquake-induced landslides and Weather-induced landslides respectively, while the fourth main session deals with Human-induced landslides. Some papers presented in a special session devoted to "Subareal and submarine landslide processes and hazard” and in a “Young Session” complete the books. Landslides and Engineered Slopes. Experience, Theory and Practice underlines the importance of the classic approach of modern science, which moves from experience to theory, as the basic instrument to study landslides. Experience is the key to understand the natural phenomena focusing on all the factors that play a major role. Theory is the instrument to manage the data provided by experience following a mathematical approach; this allows not only to clarify the nature and the deep causes of phenomena but mostly, to predict future and, if required, manage similar events. Practical benefits from the results of theory to protect people and man-made works. Landslides and Engineered Slopes. Experience, Theory and Practice is useful to scientists and practitioners working in the areas of rock and soil mechanics, geotechnical engineering, engineering geology and geology.
Download or read book Geology of the Nepal Himalaya written by Megh Raj Dhital and published by Springer. This book was released on 2015-02-11 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the geology of the entire Himalayan range in Nepal, i.e., from the Gangetic plain in the south to the Tethyan zone in the north. Without a comprehensive look at the various Himalayan zones, it is practically impossible to fully grasp the processes at work behind the formation and development of the spectacular Himalaya. However, the goal is not merely to document all the scientific ontology but rather to reveal a sound basis for the prevailing concepts. Both the early literature on Himalayan geology and contemporary trends are fully covered. For the first time, the origin, use, and abuse of common Himalayan geological terms such as the Siwaliks, Lesser Himalaya, Main Boundary Thrust, Main Central Thrust, and Tethys are discussed. The book will help readers to progress from a cognitive approach to a constructive one by linking various types of knowledge, such as seeking relations between various geological structures as well as between earlier thoughts or views and contemporary approaches.
Download or read book Analysis of Landslide Kinematics Using Multi temporal UAV Imagery La Honda California written by Jordan Alexander Carey and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: High-resolution topographic data are vital to studies of earth-surface processes. The combination of unmanned aerial vehicle (UAV) photography and structure-from-motion (SfM) digital photogrammetry provide a quickly deployable and cost-effective method for monitoring geomorphic change and landscape evolution. We acquired imagery of an active landslide in La Honda, California using a GPS-enabled quadcopter UAV with a 12.4 megapixel camera. Deep-seated landslides were previously documented in this region during the winter of 1997-98, with movement recurring and the landslide expanding during the winters of 2004-05 and 2005-06. This study documents the kinematics of a new and separate landslide immediately adjacent to the previous ones, throughout the winter of 2016-17. The Scenic Drive landslide is roughly triangular-shaped, deep-seated failure covering an area of approximately 10,000 m2. The area is underlain by SW-dipping late Miocene to Pliocene sandstones and mudstones. A ~3 m-high head scarp stretches along the northeast portion of the slide along a distance of ~100 m. The direction of movement is towards the southwest, with two prominent NW-SE striking extensional grabens and numerous tension cracks across the landslide body. In this thesis, I calculate displaced landslide volumes, derived from changes in elevation, and surface displacements from multi-temporal UAV surveys. Photogrammetric reconstruction of UAV/SfM-derived point clouds allowed creation of seven digital elevation models (DEMs) with spatial resolutions ranging from ~3 to 10 cm per pixel. I derived displacement magnitude, direction and rate by comparing multiple generations of DEMs and orthophotos and estimated displaced volumes by differencing subsequent DEMs creating DEMs of difference (DoDs). I then correlated displacements with total rainfall and rainfall intensity measurements. Geomorphic mapping of the study area identifies major landslide features, such as the head scarp, normal and thrust scarps, extensional grabens, tension cracks, and associated earthflows, documenting dominant surface processes on the slide. Additionally, I compare the accuracy of the UAV/SfM-derived DEM with a DEM sourced from a synchronous terrestrial lidar survey. Conservative measurements yield 5.4 m of maximum horizontal displacement across the central portion of the slide during the monitoring period. Over the course of the monitoring period, ~3,000 m3 of material was displaced by the landslide. Comparisons between the lidar and SfM DEMs showed that the two are comparable in the horizontal direction within 0.05 m. In the vertical direction lidar and SfM are comparable within 0.20 m in unvegetated areas. This study further demonstrates the ability of the UAV/SfM workflow to map and monitor active mass-wasting processes in regions where landslides pose a threat to the surrounding community. Additionally, this thesis assesses the erosional characteristics of two recently burned areas in northern California: the 2015 Wragg Fire and the 2016 Emerald Fire. For the 2015 Wragg Fire, I compare observed post-fire erosion with USGS post-fire debris-flow models. For the 2016 Emerald Fire, I attempt estimate eroded material through multi-sourced DoDs and compare with field measurements. The aims of this study are to (1) further demonstrate the potential of UAV-SfM techniques in geomorphic studies and hazards management, (2) quantify landslide displacements and volumes by differencing multi-temporal DEMs and (3) document various mass-wasting/erosional processes across northern California. By increasing our understanding the various mass-wasting processes affecting northern California, we can help improve disaster preparation, response and management efforts potentially reducing damages and saving lives.

Download or read book Remote Sensing Techniques for Landslides Studies and Their Hazards Assessment written by Rachid El Hamdouni and published by . This book was released on 2024-05-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landslides can cause extensive property damage and human casualties and thus influence socio-economic conditions in many countries. In recent decades, there has been a significant increase in the frequency of landslides related to climate change and the expansion of urbanized areas. The level of risk from landslides depends, among other things, on the distribution and typology of these processes and the temporal probability of these processes affecting a unit of land. Therefore, spatial mapping of these processes and knowing their frequency or temporal reactivation would provide valuable information to help us predict the hazard of these geological processes and thus evaluate the associated risks in certain areas. While it is possible to conduct landslide studies by direct ground observation, data collection in inaccessible and extensive land is time-consuming and expensive and can sometimes be very difficult. Remote sensing images (aerial, satellite, or terrestrial) are increasingly used in different landslide investigations, thus allowing the spatial and multi-temporal mapping of these processes, offering detailed monitoring of changes in the ground surface, and allowing data to obtain factors to be used in the assessment of landslide hazards. This Special Issue includes research papers with studies covering different applications of remote sensing in landslide investigations: Identification and inventory of landslides, Monitoring of landslide activity, and Spatial and temporal analysis of different factors to assess landslide hazard mapping.

Download or read book Terrigenous Mass Movements written by Biswajeet Pradhan and published by Springer Science & Business Media. This book was released on 2012-04-02 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Terrestrial mass movements (i.e. cliff collapses, soil creeps, mudflows, landslides etc.) are severe forms of natural disasters mostly occurring in mountainous terrain, which is subjected to specific geological, geomorphological and climatological conditions, as well as to human activities. It is a challenging task to accurately define the position, type and activity of mass movements for the purpose of creating inventory records and potential vulnerability maps. Remote sensing techniques, in combination with Geographic Information System tools, allow state-of-the-art investigation of the degree of potential mass movements and modeling surface processes for hazard and risk mapping. Similarly, through statistical prediction models, future mass-movement-prone areas can be identified and damages can to a certain extent be minimized. Issues of scale and selection of morphological attributes for the scientific analysis of mass movements call for new developments in data modeling and spatio-temporal GIS analysis. The book is a product of a cooperation between the editors and several contributing authors, addressing current issues and recent developments in GI technology and mass movements research. Its fundamental treatment of this technology includes data modeling, topography, geology, geomorphology, remote sensing, artificial neural networks, binomial regression, fuzzy logic, spatial statistics and analysis, and scientific visualization. Both theoretical and practical issues are addressed.
