Analysis and Modelling of River Meandering
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.
Fluvial Sedimentology VI
Understanding of rivers and their sediments, both as modern systems and as ancient counterparts in the geological record, has progressed steadily but markedly over the past several decades, with contributions by practitioners in diverse fields of geosciences and engineering. This book contains 31 papers, with authors from 13 countries, who participated in the Sixth International Conference on Fluvial Sedimentology held in Cape Town, South Africa, in 1977. True to the nature of these quadrennial conferences, the papers in this book discuss a broad range of fluvial subjects that include the character of bedforms and sediment transport in river channels, morphological and sedimentological features of modern fluvial environments, modern and ancient avulsions, internal and external controls on the behaviour of river systems, and the facies and architectural organization of alluvial deposits. A specialist volume detailing the latest advances in fluvial sedimentology. Authorship includes the leaders in the field.

Long Term Hillslope and Fluvial System Modelling
This volume presents a collection of papers given at a Rhine-LUCIFS (Land use and climate impact on fluvial systems), the aim being to bring together researchers with longstanding experience in developing concepts and modelling approaches for long term landscape evolution and scientists involved in more classical studies on the evolution of the Rhine river system. It is divided into two parts: part one reviews the Rhine river system and gives case studies to demonstrate the types of data that can be extracted from sedimentary archives. Part two provides a state of the art review on concepts for fluvial system research, as well as modelling the components of large river basins, written by leading European scientists in this field.
North Sea Region Climate Change Assessment
This book offers an up-to-date review of our current understanding of climate change in the North Sea and adjacent areas, as well as its impact on ecosystems and socio-economic sectors. It provides a detailed assessment of climate change based on published scientific work compiled by independent international experts from climate-related disciplines such as oceanography, atmospheric sciences, marine and terrestrial ecology, using a regional evaluation and review process similar to that of the Intergovernmental Panel on Climate Change (IPCC). It provides a comprehensive overview of all aspects of our changing climate, discussing a wide range of topics including past, current and future climate change, and climate-related changes in marine, terrestrial and freshwater ecosystems. It also explores the impact of climate change on socio-economic sectors such as fisheries, agriculture, coastal zone management, coastal protection, urban climate, recreation/tourism, offshore activities/energy, and air pollution.
Geomorphic Approaches to Integrated Floodplain Management of Lowland Fluvial Systems in North America and Europe
This volume provides a comprehensive perspective on geomorphic approaches to management of lowland alluvial rivers in North America and Europe. Many lowland rivers have been heavily managed for flood control and navigation for decades or centuries, resulting in engineered channels and embanked floodplains with substantially altered sediment loads and geomorphic processes. Over the past decade, floodplain management of many lowland rivers has taken on new importance because of concerns about the potential for global environmental change to alter floodplain processes, necessitating revised management strategies that minimize flood risk while enhancing environmental attributes of floodplains in...
Soil and Water Contamination
This textbook provides an overview of transport and fate processes of environmental contamination, in such a way that the reader can both understand and predict contaminant patterns in soil, groundwater, and surface water. In contract to most existing texts, soil and water pollution are treated as integrated environmental matter from a geographical/spatial perspective at point, local, regional, and catchment scales. The spatial approach links up with recent developments and trends in environmental legislation and other integrated catchment management initiatives. It consists of four coherent parts: 1. Introduction to soil and water contamination; 2. Source, role, and behavior of substances in soil and water; 3. Transport and fate processes of substances in soil and water; and 4. Patterns of substances in soil and water. Intended for undergraduate and graduate students in Earth and Environmental Sciences, who understand the fundamentals of chemistry, hydrology and soil science; may also serve as a useful reference for professionals.
