This book was released on 2018 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landslides cause significant damage to property and human lives throughout the world. Rainfall is the most common triggering factor for the occurrence of landslides. This dissertation presents two novel methodologies for assessment of rainfall-triggered shallow landslide hazard. The first method focuses on using remotely sensed soil moisture and soil surface properties in developing a framework for real-time regional scale landslide hazard assessment while the second method is a deterministic approach to landslide hazard assessment of the specific sites identified during first assessment. In the latter approach, landslide inducing transient seepage in soil during rainfall and its effect on slope stability are modeled using numerical analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Mountainous areas are challenging to manage and maintain access due to their remoteness and steep topography. Shifting hydrologic regimes from changing climate are projected to intensify these challenges. Of particular concern are the effects and uncertainties from climate change on hillslope stability that may lead to increased landslides, which adds sediment to streams, elevates flooding, and impacts downstream natural and built resources. This dissertation aimed to improve mapping landslide hazard by integrating process-based and data-driven statistical models. To achieve this, we organized the dissertation into four chapters that begins with motivation and background (Chapter 1) and a climate change vulnerability assessment to access over a large regional area (Chapter 2). Chapter 3 describes a new probabilistic model of shallow landsliding based on a physical model that is coupled with a macro-scale hydrologic model and a soil evolution model explicitly addressing spatial and temporal uncertainty. This physical model is integrated with a statistical model relating observed landslides with local site factors predisposing a hillslope to fail to produce regional-scale landslide hazards from initiation, transportation, and deposition processes (Chapter 4). Concerns about hillslope stability were identified during one of the largest climate change adaptation efforts undertaken on federal lands. This effort included a transportation vulnerability assessment conducted with research scientists and federal land managers of two national parks and two national forests in north-central Washington, USA. During this assessment documented in Chapter 2, one of the top four infrastructure sensitivities recognized was increased damage associated with landslides from projected higher winter soil moisture caused by changes in seasonal precipitation and snow accumulation. Numerous strategies were identified to increase resistance and resilience of the transportation system to this impact pathway, including information needs such as “site-specific stability analysis based on soil and geologic information” and “identification of areas sensitive to high landslide frequency.” This dissertation takes on these information priorities by developing regional landslide models and demonstrates the models in one of the four jurisdictions: North Cascades National Park Complex (NOCA), Washington. Chapter 3 of the dissertation describes our development of a hydro-climatological approach to modeling of regional shallow landslide initiation that integrates spatial and temporal dimensions of parameter uncertainty. The physically-based model estimates annual probability of landslide initiation by solving the infinite slope stability equation coupled to steady-state topographic flow routing using a Monte Carlo approach. The uncertainty of soil depth often ignored in landslide hazard modeling is address by a soil development model, and subsurface flow recharge is obtained from the Variable Infiltration Capacity macro-scale hydrologic model. Thus, the model design allows for use of future hydrologic projections to estimate changing landslide probability as climate and landscape evolve. The model is available as a component in Landlab, an open-source, Python-based landscape earth systems modeling environment. It is designed to be easily reproduced and applied in various locations utilizing HydroShare cyberinfrastructure; therefore, it can be implemented in the other three federal jurisdictions and elsewhere. To better understand landslide transport and deposition impacts, we develop empirically-based probability hazard maps from a statistically-derived susceptibility index explained in Chapter 4 of this dissertation. This empirical model integrates the influence of seven site attributes on observed landslides, inventoried by NOCA park personnel, using a frequency ratio approach. The attributes assessed included: elevation, slope, curvature, aspect, land use-land cover, lithology, and topographic wetness index. The physically-based and empirically-based models were then combined to produce an integrated probabilistic map of landslide hazard for initiation, transport, and deposition processes. Thus, these maps identify locations of high and low probability of landslide impacts within the NOCA that can be used by land managers in their design, planning, and maintenance. Improved tools such as these with incorporated uncertainty can be used to reduce system vulnerabilities and lead to adaptations that allow continue use of natural areas with reduced risks.

This book was released on 2012-01-21 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent landslide events demonstrate the need to improve landslide forecasting and early warning capabilities in order to reduce related risks and protect human lives. In this thesis, local and regional investigations were carried out to analyse landslide characteristics in the Swabian Alb region, and to develop prototypic landslide early warning systems. In the local study area, an extensive hydrological and slope movement monitoring system was installed on a seasonally reactivated landslide body located in Lichtenstein- Unterhausen. Monitoring data was analysed to assess the influence of rainfall and snow-melt on groundwater conditions, and the initiation of slope movements. The coupled hydrology-slope stability model CHASM was applied to detect areas most prone to slope failures, and to simulate slope stability using a variety of input data. Subsequently, CHASM was refined and two web-based applications were developed: a technical early warning system to constantly simulate slope stability integrating rainfall measurements, hydrological monitoring data and weather forecasts; and a decision-support system allowing for quick calculation of stability for freely selectable slope profiles. On the regional scale, available landslide inventory data were analysed for their use in evaluation of rainfall thresholds proposed in other studies. Adequate landslide events were selected and their triggering rainfall and snow-melting conditions were compared to intensity-duration and cumulative thresholds. Based on the results, a regional landslide early warning system was developed and implemented as a webbased application. Both, the local and the regional landslide early warning systems are part of a holistic and integrative early warning chain developed by the ILEWS project, and could easily be transferred to other landslide prone areas.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : The Landslide Early Warning System (LEWS) is a non-structural approach to mitigate landslide risk by alerting vulnerable communities at an early stage. This study aimed to develop a regional LEWS for rain-induced shallow landslides in Idukki, a mountainous district in India with sparse rainfall data. The landslide model consists of a rainfall component and a slope stability component. Satellite precipitation data can be used in data-sparse regions, but they must be calibrated because they tend to underestimate rainfall. To improve the accuracy of satellite data, this study used a geostatistics-based multi-criteria approach to identify optimal locations to install new rain gauges, thus enhancing the rain gauge network's monitoring capability. A rainfall threshold was developed for Idukki, accounting for intra-seasonal variations in rainfall patterns and extreme rainfall events. The slope stability component of the model is limited by the lack of high-resolution soil properties, which are time-consuming and impractical to acquire using conventional methods. To overcome this limitation, this research proposed developing empirical relationships between sub-surface resistivity and soil properties, providing a regional-scale high-resolution soil property dataset for slope susceptibility assessment. Finally, a cloud-based LEWS was developed using Google Earth Engine, combining the rainfall threshold and high-resolution slope stability models, with the advantage of readily available near real-time data, processing power, user accessibility, and the opportunity for future updates.
Book Synopsis Rainfall-Induced Soil Slope Failure by : Lulu Zhang
Download or read book Rainfall-Induced Soil Slope Failure written by Lulu Zhang and published by CRC Press. This book was released on 2018-09-03 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rainfall-induced landslides are common around the world. With global climate change, their frequency is increasing and the consequences are becoming greater. Previous studies assess them mostly from the perspective of a single discipline—correlating landslides with rainstorms, geomorphology and hydrology in order to establish a threshold prediction value for rainfall-induced landslides; analyzing the slope’s stability using a geomechanical approach; or assessing the risk from field records. Rainfall Induced Soil Slope Failure: Stability Analysis and Probabilistic Assessment integrates probabilistic approaches with the geotechnical modeling of slope failures under rainfall conditions with unsaturated soil. It covers theoretical models of rainfall infiltration and stability analysis, reliability analysis based on coupled hydro-mechanical modelling, stability of slopes with cracks, gravels and spatial heterogenous soils, and probabilistic model calibration based on measurement. It focuses on the uncertainties involved with rainfall-induced landslides and presents state-of-the art techniques and methods which characterize the uncertainties and quantify the probabilities and risk of rainfall-induced landslide hazards. Additionally, the authors cover: The failure mechanisms of rainfall-induced slope failure Commonly used infiltration and stability methods The infiltration and stability of natural soil slopes with cracks and colluvium materials Stability evaluation methods based on probabilistic approaches The effect of spatial variability on unsaturated soil slopes and more

Abstract: Buildup of pore-water pressure due to water infiltration during an extreme rainfall event is a major cause of many landslides worldwide. A competent simulation model can greatly contribute to the reliable landslide prediction and prevention. Rainfall-induced slope stability is dependent on many factors, including slope topography, rainfall hyetograph, surface runoff characteristics, soil properties, and sub-surface conditions. This thesis aims at developing an integrated analysis framework for the rainfall-induced slope stability problems. A fully-coupled groundwater-surface water interaction numerical model, HydroGeoSphere, is used to compute the transient surface runoff and sub-surface pore-water pressure responses due to rainfall simultaneously without the need to make assumptions on the infiltration rate. Therefore, rainfall hyetograph can be used directly as an input parameter in the numerical model. The computed pore-water pressure as a function of time is used as input to the computer program OpenSees. OpenSees is used to calculate slope displacements using finite element methods. Parameter estimation methods are applied to calibrate the model parameters on the basis of field data. Assessment of slope stability can be made according to the model results. It is proven that the integrated model provides a more comprehensive and reliable approach for slope safety analysis, real-time monitoring, and hazard assessment. A case study on a full-scale instrumented slope in Hong Kong is also presented to evaluate the integrated framework. The results obtained from the numerical simulation are compared with the field observation data and slope stability of the site is assessed. The integrated model is capable to provide reliable results on many aspects. Statistical analyses using Kalman Filtering are also carried out to conduct real-time slope monitoring and prediction for comparison. There are both advantages and disadvantages for the integrated model and Kalman Filtering in real-time slope monitoring and prediction.

Book Synopsis Quantitative Landslide Hazard Assessment with Remote Sensing Observations and Statistical Modelling by : Romy Schlögel
Download or read book Quantitative Landslide Hazard Assessment with Remote Sensing Observations and Statistical Modelling written by Romy Schlögel and published by . 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 Slope Safety Preparedness for Impact of Climate Change written by Ken Ho and published by CRC Press. This book was released on 2017-06-01 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many countries are increasingly threatened by major landslide disasters and fatalities due to extreme weather events which have major implications for public safety and the sustainability of infrastructure and the built environment. A further increase in such a trend could come from climate change. This book helps to fill in the gap due to the fact that landslide hazards are commonly not covered under the policy debate on climate change. The book highlights the importance of raising awareness to the challenges of landslide hazards due to climate impact. It provides a holistic frame for understanding the key issues and new tools that could be used to assess and manage the landslide risks. The book gathers contributions from 21 countries and regions in the form of national reports or summaries with respect to four key aspects: a) the methods used for evaluating changing weather and changing landslide patterns; b) the changing weather patterns; c) the changing landslide patterns and hazard scenarios; d) the applications to risk management and the formulation of adaptation measures. Recommendations are made for enhanced preparedness and resilience. Improved crisis management and areas for future work are suggested.
