This book provides essential information and recent findings on hydro-environmental issues in the Lower Danube River, particularly its hydrological and hydromorphological processes; physico-chemical features; climate and water-related hazards; and not only the biodiversity and quality but also the sustainable management and governance of its hydro-environment. Accordingly, it presents a broad range of scientific information on the lower sector of the second-longest river in Europe, which holds major economic importance and has been severely impacted by human pressures, especially since the second part of the last century. The engineering works (e.g. dams, reservoirs, levees, channelization, etc.) on the Danube and its tributaries, despite their benefits to society, have altered its flow and significantly reduced its sediment load, with consequences for hydromorphological processes and aquatic ecosystems. These ecosystems have also been affected by pollution from various sources. To promote sustainable management of the Danube River and its watershed, several strategies and measures have been developed by a number of institutions, from the European level to the national and regional levels (commissions, national authorities, non-governmental organizations, etc.). Compared to the upper and middle sectors of the Danube, the lower sector has received less attention in the international scientific literature in terms of hydro-environmental issues. The book fills this gap and provides current and original insights and findings from recent studies conducted by scientists from three countries drained by the Lower Danube River and its tributaries: Bulgaria, Romania and Serbia. This unique book will be of great scientific interest to professional engineers, policy planners and policymakers in the three countries mentioned above, helping them to implement their own sustainable development plans. It also offers a valuable resource for graduate students, researchers and stakeholders.

This volume presents a synthesis of basic biological and conservation data for more than 30 species of sturgeons (Acipenseridae), paddlefishes (Polyodontidae) and their fossil allies in the order Acipenseriformes. Since the Jurassic, the four families of sturgeon-like fish have been restricted to the Holarctic, where until very recently they flourished in most major river systems. Today, however, virtually all species of sturgeons and paddlefishes face difficult conservation issues. Papers in the first section of this volume examine paleontology, systematics, evolution and basic biology of Acipenseriformes. The second section of this volume details current conservation status for most of the world's living species of Acipenseriformes. These papers mark the first attempt to make such a global review of recent data from across the northern hemisphere. The emerging picture is discouraging, for negative anthropogenic impacts range from overfishing to water pollution, to dams and water diversion projects, and all species are threatened to some degree. The third section of the volume considers specific human impacts and responses to conservation issues. These include: the Aral Sea ecological disaster and its impact on native sturgeons; a review of methods for restoring sturgeon populations; the use of molecular techniques in developing conservation strategies; the extreme sensitivity of sturgeons and paddlefishes to overfishing; and the history of a recently convicted caviar poaching ring. The volume's summary reviews the status of all extant species and notes future directions for research on behavior, ecology and population biology that could lead to better co-ordinated international conservation efforts.

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.

Excavations on the site of this remarkable fort in northern Bulgaria (1996–2005) formed part of a long-term program of excavation and intensive field survey, aimed at tracing the economic as well as physical changes which mark the transition from the Roman Empire to the Middle Ages, a program that commenced with the excavation and full publication of the early Byzantine fortress/city of Nicopolis ad Istrum. The analysis of well-dated finds and their full publication provides a unique database for the late Roman period in the Balkans; they include metal-work, pottery (local and imported fine ware), glass, copper alloy finds, inscriptions and dipinti (on amphorae), as well as quantified environmental reports on animal, birds, and fish with specialist reports on the archaeobotanical material, glass analysis, and querns. The report also details the results of site-specific intensive survey, a new method developed for use in the rich farmland of the central Balkans. In addition, there is a detailed report on a most remarkable and well-preserved aqueduct, which employed the largest siphon ever discovered in the Roman Empire. This publication will provide a substantial database of material and environmental finds, an invaluable resource for the region and for the Roman Empire: material invaluable for studies, which seeks to place the late Roman urban and military identity within its regional and extra-regional economic setting.

In the prehistoric Copper Age, long before cities, writing, or the invention of the wheel, Old Europe was among the most culturally rich regions in the world. Its inhabitants lived in prosperous agricultural towns. The ubiquitous goddess figurines found in their houses and shrines have triggered intense debates about women's roles. The Lost World of Old Europe is the accompanying catalog for an exhibition at New York University's Institute for the Study of the Ancient World. This superb volume features essays by leading archaeologists as well as breathtaking color photographs cataloguing the objects, some illustrated here for the first time. The heart of Old Europe was in the lower Danube valley, in contemporary Bulgaria and Romania. Old European coppersmiths were the most advanced metal artisans in the world. Their intense interest in acquiring copper, Aegean shells, and other rare valuables gave rise to far-reaching trading networks. In their graves, the bodies of Old European chieftains were adorned with pounds of gold and copper ornaments. Their funerals were without parallel in the Near East or Egypt. The exhibition represents the first time these rare objects have appeared in the United States. An unparalleled introduction to Old Europe's cultural, technological, and artistic legacy, The Lost World of Old Europe includes essays by Douglass Bailey, John Chapman, Cornelia-Magda Lazarovici, Ioan Opris and Catalin Bem, Ernst Pernicka, Dragomir Nicolae Popovici, Michel Séfériadès, and Vladimir Slavchev.

The Danube River Basin is shared by 19 countries and there is no river basin in the world shared by so many nations. Europe’s second largest river basin with a total 2 area of about 800,000 km is also home to 83 million people of different cultures, languages and historical backgrounds. Management of common water sources and overcoming dif?culties caused by droughts and ?oods requires co-operation between the countries. In 1971 these c- mon interests stimulated the hydrologists of – at that time – eight Danube countries to begin regional co- operation in the framework of the International Hydrological Decade of UNESCO. The result of this research was The Hydrological Monograph of the Danube and its Catchment, which was published in 1986. Since 1975 this co-operation has continued under the umbrella of the International Hydrological Programme (IHP) of UNESCO. In the past 20 years political turbulence has caused an increase in the number of countries, making the co-operation dif?cult at times.

This volume offers a comprehensive review of the chemical, biological and hydromorphological quality of the Danube. The first part examines the chemical pollution of surface waters, focusing on organic compounds (with special emphasis given to EU WFD priority substances and Danube River Basin specific pollutants), heavy metals and nutrients. Attention is also given to pollution of groundwater and drinking water resources by hazardous substances and to radioactivity in the Danube. The second part highlights the biology and hydromorphology of the Danube. It focuses on benthic macroinvertebrates, phytobenthos, macrophytes, fish, phytoplankton as well as microbiology, with chapters dedicated to gaps and uncertainties in the ecological status assessment and to invasive alien species. Further chapters dealing with the hydromorphology, sediment management and isotope hydrology complete the overall picture of the status of the Danube.

Six species of sturgeons are native to the Danube River Basin. The need for conservation action is urgent, given that recent observations in the Lower Danube indicate that all sturgeon populations are near extinction. Due to the high commercial value of sturgeon products, in particular caviar, the pressure from proaching and illegal trade remains intense. These species will not survive unless fishing practices are greatly addressed, and both migration routes and habitats for all life-cycle stages are protected. Through national action and international co-ordination, this action plan aims to secure viable populations of all Danube sturgeon species by sustainable management and restoration of their natural habitats and migratory corridors
