The second-longest European river after the Volga, the Danube is one of the world’s most important rivers in terms of its geographical and historical significance. In recent history, it has served as a major international waterway and numerous cities, including four capitals, have been founded on its banks. The 2826km-long Danube has a watershed measuring 801,093 km2 that is now shared between 19 countries, from its source in the Black Forest to the Black Sea, into which it pumps an average of 827 km3 of water a year. This book describes and explains key landscape values interactions (geographical, cultural and natural heritage). It also identifies the threats and various types of human impact affecting this system in all the countries of the Danube River Basin, based on the investigations and perspectives of a team of experienced naturalists, and in the context of the early 21st century, in which the human-nature relationship is still far from balanced. These studies demonstrate how biodiversity, conservation and ecological studies can help us successfully promote mutual cooperation and combine our efforts to address problems as a responsible continent.

Riverine Ecosystem Management

Continuous riverbed incision is the main driver of decoupling fioodplains from the required water stage-dependent dynamics ... human (anthropogenic) disturbances have greater impacts on the fine sediment dynamics than natural processes.

This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

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 influenced by local embankments and upstream dams. Recognition of the failure of old perspectives on river management and the need to enhance environmental sustainability has stimulated a new approach to river management. The manner that river restoration and integrated management are implemented, however, requires a case study approach that takes into account the impact of historic human impacts to the system, especially engineering. The river basins examined in this volume provide a representative coverage of the drainage of North America and Europe, taking into account a range of climatic and physiographic provinces. They include the 1) Sacramento (California, USA), 2) San Joaquin (California), 3) Missouri (Missouri, USA), 4) Red (Manitoba, Canada and Minnesota, USA), 5) Mississippi (Louisiana, USA), 6) Kissimmee (Florida, USA), 7) Ebro (Spain), 8) Rhone (France), 9) Rhine (Netherlands), 10) Danube (Romania), and 11) Volga (Russian Federation) Rivers. The case studies covered in these chapters span a range of fluvial modes of adjustment, including sediment, channel, hydrologic regime, floodplains, as well as ecosystem and environmental associations.

This book presents an overview of the fluvial processes theory developed in the former USSR at Lomonosov Moscow State University for the last 50 years, following the famous manuscript by Professor Makkaveev in 1955. Even being published solely in the Russian language, the theory and the author of the book, Prof. Roman Chalov, are well known in the World. This book consolidates for the first time in English, Chalov's work for the global audience. The book demonstrates how principles from fluvial geomorphology and hydrology are used to develop an ecosystem approach to river analysis and management. Despite a strong tradition in fluvial geomorphology work in the USSR, unfortunately, little has been made of insights provided on the international stage. The fluvial processes theory accepted in USSR was somewhat isolated during the long period of development from the English-language literature. The studied rivers are mostly located in Northern Eurasia and much different from those described in classical English-language works. Chalov allows the readers to interconnect two Worlds in Geomorphology, building bridges between the classical international geomorphology and the equally in-depth and thorough but isolated research in the USSR.
