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.
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

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
