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

The book illustrates theories of sustainable development from physical, chemical and biological aspects, and then introduces technologies to prevent pollution of water, air, solid waste and noise, finally concludes with ecological environmental protection and restoration techniques. With interdisciplinary features and abundant case studies, it is an essential reference for researchers and industrial engineers.

Document from the year 2010 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: -, Dresden Technical University (Institute of Soil Science and Site Ecology), course: -, language: English, abstract: Soil properties are not only influenced by geographical factors, such as parent material, location and latitude. Often differences in land uses (forest, rubber plantation, paddy field, bare land) are known to have specific effects on soil properties. In the context of the project Living Landscapes China (LILAC) these effects were evaluated and the characteristics of soil types under changing conditions in two transects (altitude and parent material in transect 1, land uses in transect 2) in the Naban River Watershed National Nature Reserve were classified. We used field investigations to classify the soil types, as well as laboratory analyses to quantify specific characteristics in samples, taken from the profiles. Soil physical (bulk density, water content, texture) and chemical parameters (total contents of carbon, nitrogen and macro nutrients, ECEC) were investigated. While differences in altitude did not seem to have profound influences on the soils, effects of land uses were pronounced especially in the first 10 to 20 cm of soil profiles. Soils under forests contain between 1.3 % - 2 % SOC and 0.15 % - 0.17 % TN in the Ah horizon. With contents of 1.2 % SOC and 0.11 % TN (Ah horizon) the profile under agricultural use (paddy rice) clearly contains less SOC and TN than the forest profiles. Fertilization also seemed to have an influence resulting in higher contents of Ca (6 - 12 times) and Mg (up to 4 times) for the topsoil as well as a higher effective CEC (7.9 - 9.3 cmolc/kg) for subsoil horizons of the paddy field compared to forest and rubber sites. The profile under bare land (transect 1) showed higher leaching of nutrients due to the missing soil cover. Thus, Al and Fe contents were enriched, while the effective CEC (5.1 cmolc/kg
