This book contains the written versions of invited lectures presented at the Gerhard H. Jirka Memorial Colloquium on Environmental Fluid Mechanics, held June 3-4, 2011, in Karlsruhe, Germany. Professor Jirka was widely known for his outstanding work in Environmental Fluid Mechanics, and 23 eminent world-leading experts in this field contributed to this book in his honour, providing high-quality state-of-the-art scientific information. The contributions cover the following key areas of Environmental Fluid Mechanics: Fluvial Hydraulics, Shallow Flows, Jets and Stratified Flows, Gravity Currents, Mass Transfer and Small-Scale Phenomena, and include experimental, theoretical and numerical studies. In addition, former co-workers of Professor Jirka provide an extensive summary of his scientific achievements in the field.

A stream flowing in alluvium deforms its bed surface, forming ripples, dunes, bars, etc., and, in many instances, it deforms its channel entirely, thereby creating meandering or braiding patterns. It could be said that, in general, an alluvial stream and its deformable boundary undergo a variety of fluvial processes leading to the emergence of a multitude of alluvial forms. This book concerns the physics and analytical treatment of various fluvial processes and the associated alluvial bed and plan forms listed above. Following an introductory chapter on the basics of turbulent flow and sediment transport, the book covers the origin, geometric characteristics and effects of bed forms, from small- to meso-scale (ripples, dunes, alternate and multiple bars); the initiation, geometry and mechanics of meandering streams; the computation of flow, bed deformation and the planimetric evolution of meandering streams; and braiding and delta formation. The book also covers the regime concept, the time-development of a stream towards its regime state, and the formulation of stable, or equilibrium, morphology. The book distinguishes itself by its comprehensive analysis and discussion of key processes involved in large-scale river morphodynamics. The book was written primarily for researchers and graduate students of hydraulic engineering, water resources and related branches of earth sciences, but it will also prove useful for river engineers and managers.

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.

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. The book is divided into six topics: A - Integrated sediment management at the river basin scale B - Sediment transport C - River morphodynamics D - Hydromorphology meets ecology E - Reservoir sustainability F - Social, economic and political aspects of sediment management The book also includes five special topics: 1 - Hydropower and sediment management, 2 - Navigation and river morphology, 3 - Innovative measurement techniques, 4 - SEDITRANS – Sediment transport in fluvial, estuarine and coastal environment, 5 - Sustainable land management. The aforementioned subject areas will be of interest to academics, engineers and professionals.
