Book Description :

The genesis of soils has been seen mostly as an autochthonistic process, that is, formation in situ. However, soil geomorphologists have recognized addition and loss of materials, for example, through eolian and colluvial processes, as a major contribution to allochthonistic soil formation. The most important characteristic of these soils is the lithological discontinuity, which separates the lower residual material from the upper allochthonic soil. The chapter deals with (1) developing a model joining the ideas of in situ formation and near-surface processes such as adding or removing material, (2) the pedogenetic processes in soils with lithological discontinuities, and (3) the effect of lithological discontinuities on physical and chemical properties of soils.

Book Description :

Cover beds form a rather uniform veil of most slopes in Central Europe and, most likely, all over the mid-latitudes. Accordingly, their properties are of utmost importance for the formation of soils, for slope hydrology, and for slope dynamics. More research is, however, needed, as there is still insufficient information on the properties of cover-bed successions reaching deeper than 1 m, and there are still many areas where cover beds have not yet been studied at all. The potential use of cover beds for paleoenvironmental reconstructions is also still limited by the unsatisfactory techniques that are currently available for their numerical dating. Furthermore, better techniques for modeling the distribution and the properties of cover beds are required to forecast their influence on flooding events.

Book Description :

Slope deposits are common in any inclined relief. So-called cover beds may veil entire landscapes, in which case they are commonly overlooked or confused with soil horizons. This book focuses on these widespread deposits and discusses their properties, genesis, and age mainly in subdued mountains of Central Europe, where to date most research on the matter has been conducted. The ecological consequences of such slope deposits on soils, slope water dynamics, and slope failures are addressed. Finally, transfer of the cover-bed concept to other mid-latitude regions is attempted for the reconstruction of landscape evolution. This unique compilation, covering several decades of a facies-oriented approach to slope-deposit research, delivers deep insight into the wide field of research on cover beds and encourages researchers all over the world to take an in-depth look at the critical zone as to its possible stratified nature.

Book Description :

Slope deposits that formed by unconcentrated dislocation and that cover slopes in a rather uniform way are referred to as “cover beds” in this book. They consist of materials from upslope but may contain admixed eolian matter. They are commonly multilayered with the individual layers separated by disconformities (lithological discontinuities). The main scope of this book is to provide a comprehensive state of the art of this particular type of slope deposits in the mid-latitudes. Being a major component of the near-surface ground, cover beds should be included as an integral part into the so-called critical-zone concept and may partially replace the existing “biomantle concept” for the mid-latitudes.

Book Description :

Numerous case studies carried out in the subdued mountains of Germany during the last decades have revealed that periglacial cover beds play a decisive role in hillslope hydrology. Considering the omnipresence of cover beds in sloped terrain of the mid-latitudes, knowledge of slope-water paths is crucial not only for flood forecast but also for understanding how contaminants pass through ecosystems. Since periglacial cover beds are usually composed of different sedimentary layers, they show a high spatial variability of physical soil parameters, which are, in turn, responsible for small-scale variations of the hydraulic properties. Regardless of bedrock type, the observations reported in this chapter from different regions lead to the conclusion that there is a clear relationship between subsurface layering and runoff-generation processes. The hydraulic anisotropic structure of the deepest (basal) layer is the major factor controlling subsurface water-flow paths. On one hand, this layer acts as an aquitard for seeping water because of its high bulk density. On the other hand, once water has percolated into this layer, it is able to flow in lateral directions because of the coarse clasts oriented parallel to the slope. Therefore, such a cover bed may be treated neither as an aquifer nor as an aquiclude. Besides, as a function of pre-moisture, a nonlinear runoff response to precipitation or snow-melt of the investigated catchments was identified.

Book Description :

The occurrence and spatial distribution of cover beds are decisive for modern hillslope morphodynamics. This aspect is strongly associated with the geotechnical properties of cover beds and especially with their anisotropy. The impact of periglacial cover beds on mass movements, in particular landslides in subdued mountains, will be discussed in this section. The case studies in this chapter show that soil-physical and soil-mechanical properties significantly influence the forces in periglacial cover beds and, thus, directly control the slope stability. In contrast to long-lasting stable geomorphological factors, the reduction of shear strength, friction angle, and cohesion as well as the deformability may induce abrupt instability. Abrupt instabilities in periglacial cover beds particularly arise, when the soil-water content increases and, consequently, both the pore water and the hydrostatic pressures rise. In particular, we show that landslides to a large extent occur in hillslope sediments which are weakly consolidated and sensitive to water penetration.

Book Description :

Cover beds are usually not regarded of use for relative dating. The examples discussed in this chapter demonstrate otherwise. Central European cover beds usually are of Pleistocene age, and they can be utilized for distinguishing older landforms, such as slope failures, covered by one or more cover beds, from those which are not covered by periglacial deposits. In the western USA, where intervening soil-forming episodes provide a stratigraphic framework for such deposits, the stratigraphic value of cover-bed and soil successions is tested on various types of landforms. However, dating landforms relatively by overlying cover beds calls for due consideration of erosion-induced hiatuses and of tectonically induced processes out of phase with those driven by climate.

Book Description :

Slope deposits, which veil entire slopes or large parts of them in a rather uniform manner (cover beds), are ubiquitous in the subdued mountains of Central Europe (e.g., ). Here, we show that successions of cover beds are not restricted to this area but occur in many other regions of rather different natural inventories, such as the European Alps, the Russian Plain, south-central Turkey, and the western USA (Great Basin and Rocky Mountains). Cover beds usually form sequences of two or more distinct layers, and their distribution depends on the geomorphic, climate-driven processes of their formation. As they influence pedogenesis, they contribute to the understanding of soil properties and soil distribution: horizon boundaries occur at depths where cover-bed properties change. The properties of the layers and of the soils developed in them are different per region: in humid areas layers free of admixed loess components, thus being solely influenced by weathered local materials, are frequent, whereas in dry regions such layers have not yet been reported. In several areas studied in this chapter, paleosols either occur within cover-bed successions or have been reallocated and incorporated into the cover beds. This provides handles to the ages of layers. The layer successions slowly change with elevation but show a drastic break at around the timberline where Holocene rather than Pleistocene periglacial slope processes gained supremacy.

Book Description :

This doctoral thesis presents a novel approach to landslide risk assessment that explores the various dimensions of landslide risk in an integrated perspective. The research approach introduced here is tailored for use with landslide databases and Geographic Information Systems (GIS). A landslide susceptibility model is at the heart of this new approach, enabling to identify and delineate areas at risk of landslides and to assess infrastructure exposure. Landslide risk is a pressing societal issue that is still poorly understood. Temporal landslide hazard is derived from landslide frequency statistics and a hydrological simulation approach to estimate triggering thresholds. These methods are integrated into a powerful toolset for cost modeling that uses historical data to compile, model, and extrapolate damage costs on different spatial scales over time. The combination of this toolset with techniques to analyze fiscal cost impacts supports integrated risk assessment by quantifying the economic relevance of landslide losses.

Book Description :

The Periglacial Environment, Third Edition, provides an authoritative overview of the worldâ??s cold, non-glacial environments. Emphasis is placed upon the North American and Eurasian polar lowlands, but examples are also drawn from Antarctica, the Qinghai-Xizang (Tibet) Plateau, and the northern mid-latitudes. First published in 1976 and subsequently revised in 1996, the text has been the international standard for over 30 years. The Third Edition continues to be a personal interpretation of the frost-induced conditions, geomorphic processes, and landforms that typify periglacial environments. The text is divided into four parts. Part One discusses the periglacial concept and its interactions with geomorphology, geocryology and Quaternary science. It also outlines the range and variability of periglacial climates and the degree to which landscapes are in geomorphic equilibrium with prevailing periglacial conditions. Part Two describes present-day terrain that is either underlain by permafrost or experiencing intense frost action. The roles played by cryogenic weathering, ground ice, mass wasting, running water, wind action, snow and ice, and coastal processes are systematically analysed. Part Three summarizes evidence for the existence of periglacial conditions during the cold periods of the Pleistocene, with special reference to the mid-latitudes of Europe and North America. Part Four illustrates the geotechnical problems associated with human activity and resource development in periglacial environments, and discusses the potential impact of global climate change in the northern high latitudes. This excellent textbook is an invaluable resource for second and third year undergraduate students of Physical Geography, Geology, Environmental Science and Earth Science. The Periglacial Environment, Third Edition is also an informative reading for professionals, researchers and lecturers working and teaching in the field.

Book Description :

Understanding the sediments deposited by glaciers or other cold-climate processes assumes enhanced significance in the context of current global warming and the predicted melt and retreat of glaciers and ice sheets. This volume analyses glacial, proglacial and periglacial settings. Papers include topics such as sedimentation at termini of tidewater glaciers, poorly understood high-mountain features, and slope and aeolian deposits that have been sourced in glacial and periglacial regions and subsequently transported and deposited by azonal processes. Difficulties encountered in inferring Pleistocene and pre-Pleistocene cold-climate conditions when the sedimentary record lacks specific diagnostic indicators are discussed. The main objective of this volume is to establish the validity and limitations of the evidence that is used to achieve reliable palaeogeographic and palaeoclimatic reconstructions. On the much longer geological timescale, an understanding of ice-marginal and periglacial environments may better prepare us for the unavoidable reversal towards cooler and perhaps even glacial times in the future.
