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.
This book provides an overview of advances in experimental, numerical modelling, and theoretical aspects of environmental hydraulics. By highlighting the latest findings on processes in natural aquatic systems, solutions for civil engineering and water resources management, with a special focus on interdisciplinary cooperation between Earth scientists, ecologists, biologists and hydraulic engineers that have helped to mitigate the impacts of anthropopressure on river habitats, it provides both researchers and practitioners with first-hand information about the latest trends in hydraulic research. The book combines peer-reviewed versions of invited lectures and regular presentations at the 40th International School of Hydraulics, held May 23–26, 2023, in Kąty Rybackie, Poland. With contributions from world-leading experts and young researchers, many areas of environmental hydraulics are addressed here, including recent findings in numerical modelling and laboratory and field studies related to sediment and pollutant transport processes in rivers, fluvial morphodynamics, flow in vegetated channels, hydraulic structures in rivers and estuaries, and freshwater fish protection.
Seminar paper from the year 2024 in the subject Politics - Region: Africa, Addis Ababa University (Department of Public Administration and Development Management), course: Public Policy Concepts and Principles, language: English, abstract: Ethiopia's economy is heavily reliant on agriculture, with approximately 85% of the total employment located in the agricultural sector. Rural land is a crucial source of income and plays a significant role in providing food for the population. However, Ethiopia has faced persistent food insecurity, especially in rural areas, due to factors such as small landholdings, land degradation, and the impact of climate change and drought. This paper examines the s...
This book presents an overview of current research problems and advances in theoretical and applied aspects of environmental hydraulics. The rapid development of this branch of water studies in recent years has contributed to our fundamental understanding of processes in natural aquatic systems and helped provide solutions for civil engineering and water resources management. The book features comprehensively reviewed versions of invited lectures and regular presentations given at the 38th International School of Hydraulics, held May 21–24, 2019, in Łąck, Poland. With papers by leading international experts as well as young researchers from around the globe, it covers recent findings from laboratory and field studies, numerical modeling related to sediment and pollutant transport processes in rivers, fluvial morphodynamics, flow in vegetated channels and hydraulic structures in rivers and estuaries.
Rivers form one of the lifelines in our society by providing essential services such as availability of fresh water, navigation, energy, ecosystem services, and flood conveyance. Because of this essential role, mankind has interfered continuously in order to benefit most and at the same time avoid adverse consequences such as flood risk and droughts. This has resulted in often highly engineered rivers with a narrow set of functions. In the last decades rivers are increasingly considered in a more holistic manner as a system with a multitude of interdependent processes. River research and engineering has therefore added to the river fundamentals also themes like ecohydraulics, consequences of...
