This book presents selected contributions of the 34th International School of Hydraulics that was held in May 2015 in Zelechów, Poland. It gives an overview about the state of the art in environmental hydraulics. A special emphasis is put upon physical, biochemical and ecological processes that act at interfaces in natural surface water bodies but also other important hydraulic problems are considered. The achievements of well-known researchers from all over the world as well as the results obtained by young researchers, among others within a Marie Curie funded Initial Training Network, led by the University of Padua (HYTECH - HYdrodynamic Transport at Ecologically Critical Heterogeneous Interfaces) are gathered in this volume.

The state-of-the-art in water-worked bed hydraulics can only be examined through a careful exploration of the experimental (both laboratory and field) results via theoretical development. This book is primarily focused on the research aspects that involve a comprehensive knowledge of sediment dynamics in turbulent flows, as the most up-to-date research findings in the field are presented. It begins with two reviews on bedload transport and water-work bed experimental studies. The sediment dynamics is then analyzed 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 results from field studies. It is intended as a course guide for field professionals, keeping up with modern technological developments. Therefore, as a simple prerequisite, readers should have a basic knowledge of hydraulics to an undergraduate level.

An environmental interface is defined as a surface between two abiotic or biotic systems, in relative motion and exchanging mass, heat and momentum through biophysical and/or chemical processes. These processes fluctuate temporally and spatially. The book first treats exchange processes occurring at the interfaces between atmosphere and the surface of the sea, and atmosphere and land surface. These exchanges include the effect of vegetation, transport of dust and dispersion of passive substances within the atmosphere. Processes at the environmental interfaces of freshwater, such as gas-transfer at free-surfaces of rivers, advective diffusion of air bubbles in turbulent water flows and boundary-layers phenomena in vegetated open channels are also described. Finally, the book deals with the phenomena that affect transport of material to and from the surface of an organism, including molecular and turbulent diffusion. The relevant issues related to mass transfer to and from benthic plants and animals are further considered in detail. The book will be of interest to graduate students and researchers in environmental sciences, civil engineering and environmental engineering, (geo)physics and applied mathematics.

This book contains the written, thoroughly reviewed versions of both invited lectures and regular presentations given at the 36th International School of Hydraulics, held at Jachranka in Poland on May 23–26, 2017. The contributions cover recent findings in the areas of mathematical modeling as well as experimental investigations related to free surface flows and pollution, sediment and heat transport processes in rivers. Better understanding of environmental flows requires cognition of physical, chemical and biological attributes of flowing water and therefore hydraulic research becomes strongly interdisciplinary field of science. The authors also realize that fundamental knowledge of environmental hydraulics problems is absolutely essential for planning and design of systems to manage water resources. Nowadays the readers face a rapid development of hydraulic research due to a boom in the computer sciences and measurement techniques and this is what this book is about. Eminent world leading experts in this field and young researchers from sixteen countries from all over the world contributed to this book.

There are several physico-chemical processes that determine the behavior of multiphase fluid systems – e.g., the fluid dynamics in the different phases and the dynamics of the interface(s), mass transport between the fluids, adsorption effects at the interface, and transport of surfactants on the interface – and result in heterogeneous interface properties. In general, these processes are strongly coupled and local properties of the interface play a crucial role. A thorough understanding of the behavior of such complex flow problems must be based on physically sound mathematical models, which especially account for the local processes at the interface. This book presents recent findings on the rigorous derivation and mathematical analysis of such models and on the development of numerical methods for direct numerical simulations. Validation results are based on specifically designed experiments using high-resolution experimental techniques. A special feature of this book is its focus on an interdisciplinary research approach combining Applied Analysis, Numerical Mathematics, Interface Physics and Chemistry, as well as relevant research areas in the Engineering Sciences. The contributions originated from the joint interdisciplinary research projects in the DFG Priority Programme SPP 1506 “Transport Processes at Fluidic Interfaces.”

Sediment dynamics in fluvial systems is of great ecological, economic and human-health-related significance worldwide. Appropriate management strategies are therefore needed to limit maintenance costs as well as minimize potential hazards to the aquatic and adjacent environments. Human intervention, ranging from nutrient/pollutant release to physical modifications, has a large impact on sediment quantity and quality and thus on river morphology as well as on ecological functioning. Truly understanding sediment dynamics requires as a consequence a multidisciplinary approach.River Sedimentation contains the peer-reviewed scientific contributions presented at the 13th International Symposium on River Sedimentation (ISRS 2016, Stuttgart, Germany, 19-22 September 2016), and includes recent accomplishments in theoretical developments, numerical modelling, experimental laboratory work, field investigations and monitoring as well as management methodologies.

Amplified climate change and ecological sensitivity of polar and cold climate environments are key global environment issues. Understanding how projected climate change will alter surface environments in these regions is only possible when present day source-to-sink fluxes can be quantified. The book provides the first global synthesis and integrated analysis of environmental drivers and quantitative rates of solute and sedimentary fluxes in cold environments, and the likely impact of projected climate change. The focus on largely undisturbed cold environments allows ongoing climate change effects to be detected and, moreover, distinguished from anthropogenic impacts. A novel approach for co-ordinated and integrative process geomorphic research is introduced to enable better comparison between studies. This highly topical and multidisciplinary book, which includes case studies covering Arctic, Antarctic, and alpine environments, will be of interest to graduate students and researchers in the fields of geomorphology, sedimentology and global environmental change.

Phytorestoration of Abandoned Mining and Oil Drilling Sites presents case studies and the latest research on the most effective methods to address the large amounts of waste materials released due to mining and oil drilling. In particular, phytoremediation is described as a novel, eco-friendly, cost-effective method for extracting toxic compounds by plants for the restoration of contaminated sites. Plantings on these contaminated areas lead to the removal of toxic substances such as heavy metals and hydrocarbons, improvement in the physicochemical and biological properties of the soil, long-term forest ecosystem rehabilitation, restoration of ecosystem productivity, stability and biological diversity, and reductions in CO2. Utilizing worldwide examples, this book discusses the potential of phytoremediation as an ideal solution for sites contaminated by mining and oil drilling sites. Includes exploration of efficient plants for restoring contaminated former mining and oil drilling sites Addresses adverse impacts of toxicants released from mining activities on living organisms, including human health Presents characteristics of contaminated former mining and oil drilling sites
