This edited collection addresses the dynamics of the post-Communist transition in Central Eastern Europe. Its contributors present a detailed analysis of the events unfolding during the last three decades in the region, focusing in particular on identity-building processes and reforms in Belarus, Bulgaria, Czechia, Estonia, Hungary, Latvia, Lithuania, Moldova, Poland, Romania, Slovakia, and Ukraine. The contributors outline reasons why some of these states accomplished a decisive break with the Communist past and became members of European and transatlantic structures, while some opted for pseudo-transition and fostered hybrid political regimes, jeopardizing their genuine integration with the West. A group of states which decided to preserve their Communist legacy is also explained. The collection describes and scrutinizes the formation of geopolitical affiliations and the evolution of discourses of belonging. It also traces the fluctuating dynamics of national decision-making and institution-building, as many of the post-Communist states reconsider and re-elaborate their initial ideas and visions of Europe today. Finally, the collection brings to light the rapidly changing perceptions of the region by the major global actors—the European Union, People’s Republic of China, Russian Federation, and others.

This thesis examines the morphological changes of non-tidal meandering rivers at the spatial scale of several meanders. With this purpose, a physics-based mathematical model, MIANDRAS, has been developed for the simulation of the medium-term to long-term evolution of meandering rivers. Application to several real rivers shows that MIANDRAS can properly simulate both equilibrium river bed topography and planimetric changes. Three models of different complexity can be obtained by applying different degrees of simplification to the equations. These models, along with experimental tests and field data, constitute the tools for several analyses. At conditions of initiation of meandering, it is found that river bends can migrate upstream and downstream. This depends on meander wave length and width-to-depth ratio, irrespective of whether the parameters are in the subresonant or the superresonant range.

This monograph discusses the mechanics of Meandering Rivers with the help of the mathematical and modeling tools built up in the previous monograph of the same Authors (monograph 1 of the present series). After introducing the reader to the ubiquitous character of meandering streams, we discuss the hydrodynamics of curved channels with fixed beds and banks. Next, we extend the analysis to account for the mobile character of the bed and show that it gives rise to the alternate sequence of riffles and pools that characterize river meanders. Allowing for the erodible character of the river banks then allows to build up a rational theory of meander formation able to explain most of the features observed in nature: meander growth, migration, skewing, multiple loops, cutoffs and meander belts.

Rivers and Floodplains is concerned with the origin, geometry, water flow, sediment transport, erosion and deposition associated with modern alluvial rivers and floodplains, how they vary in time and space, and how this information is used to interpret deposits of ancient rivers and floodplains. There is specific reference to the types and lifestyles of organisms associated with fluvial environments, human interactions with rivers and floodplains, associated environmental and engineering concerns, as well as the economic aspects of fluvial deposits, particularly the modeling of fluvial hydrocarbon reservoirs and aquifers. Methods of studying rivers and floodplains and their deposits are also discussed. Although basic principles are emphasized, many examples are detailed. Particular emphasis is placed on how an understanding of the nature of modern rivers and floodplains is required before any problems concerning rivers and floodplains, past or present, can be addressed rationally. Rivers and Floodplains is designed as a core text for senior undergraduate and graduate students studying modern or ancient fluvial environments, particularly in earth sciences, environmental sciences and physical geography, but also in civil and agricultural engineering. College teachers, researchers, and practising professionals will also find the book an invaluable reference. Presents a process-based approach, which is relevant to modern curricula. Discusses methods of studying rivers and floodplains and their deposits. Provides many detailed examples throughout the text. Emphasises the basic principles of this subject. As the first synthesis of this entire field, it will be a must-have for all students studying modern or ancient fluvial environments. Teachers, researchers and practising professionals will find this an invaluable reference tool. Rivers and Floodplains will also be of interest to geologists, geographers and engineers.

The sinuous form and peculiar evolution of meandering rivers has long captured the imagination of people. Today, meandering rivers exist in some of the most densely populated areas in the World, where they provide environmental and economic wealth and opportunities, as well as posing hazards. Through geological time, the ancestors of these modern meanders built deposits that are now host to mineral resources, groundwater, and hydrocarbons. This Special Publication illustrates the breadth of current research on meandering rivers and their deposits. The collection of research papers demonstrates the state of science on fluvial process–product relationships. The articles cover fundamental and applied studies of both modern and ancient rivers, are based on state-of-the-art technology, include complementary philosophical approaches, and span a wide range of spatial and temporal scales. This book includes some of the most recent advances in the study of the morphodynamics and sedimentology of meandering rivers, and is an important resource for those who want to investigate fluvial systems and their deposits.

Meandering patterns shaped by fluid flows are found over a broad range of landscapes, from bedrock channels to rivers and estuaries, deep-marine environments, supraglacial streams and other planets such as Mars and Venus. During the last six decades, meanders have been widely investigated by researchers from different fields, such as fluid mechanics, geomorphology, ecology, civil- and petroleum engineering, and geology. This volume seeks to push the science of meandering forward by bringing together insights gained from field, laboratory and numerical investigations of meandering streams found in distinct environmental and geological contexts. The authors pay particular attention to the interactions between autogenic and allogenic processes that affect meander kinematics and the resulting morphology, sedimentology and stratigraphic architecture. The findings presented in this volume contribute to a better understanding of stream meandering in diverse settings, with broad implications for stream and wetland restoration, land management, infrastructure design, oil exploration and production, carbon sequestration, hazard mitigation and planetary palaeoenvironmental reconstructions.

The state-of-the-art in fluvial hydrodynamics can be examined only through a careful exploration of the theoretical development and applied engineering technology. The book is primarily focused, since most up-to-date research findings in the field are presented, on the research aspects that involve a comprehensive knowledge of sediment dynamics in turbulent flows. It begins with the fundamentals of hydrodynamics and particle motion followed by turbulence characteristics related to sediment motion. Then, the sediment dynamics is analysed from a classical perspective by applying the mean bed shear approach and additionally incorporating a statistical description for the role of turbulence. The work finally examines the local scour problems at hydraulic structures and scale models. It is intended to design as a course textbook in graduate / research level and a guide for the field engineers as well, keeping up with modern technological developments. Therefore, as a simple prerequisite, the background of the readers should have a basic knowledge in hydraulics in undergraduate level and an understanding of fundamentals of calculus.

Tectonic geomorphology is the study of the interplay betweentectonic and surface processes that shape the landscape in regionsof active deformation. Recent advances in the quantification ofrates and physical basis of tectonic and surface processes haverejuvenated the field of tectonic geomorphology. Modern tectonicgeomorphology is an exciting and highly integrative field whichutilizes techniques and data derived from studies of geomorphology,seismology, geochronology, structure, geodesy, and Quaternaryclimate change. While emphasizing new insights from the last decadeof research, Tectonic Geomorphology reviews the fundamentals of thesubject which include the nature of faulting and folding, thecreation and use of geomorphic markers for tracing deformation,chronological techniques which date deformation, geodetictechniques for defining recent deformation, and paleoseismologicapproaches to calibrate past deformation. The overall focus of this book is on new interpretations oflandform evolution and insights on the interplay between surfaceprocesses and tectonics that emerge from integrative studies.
