This book offers a comprehensive overview of recent advances in environmental hydraulics, encompassing experimental research, numerical modelling, and theoretical developments. Framed by the pressing global water challenges - Too Much, Too Little, Too Polluted - the contributions emphasise the pivotal role of hydraulics in understanding and safeguarding the health of rivers, lakes, and other aquatic ecosystems. Drawing on the latest insights into natural aquatic processes and practical solutions for civil engineering and water resources management, the volume highlights the importance of interdisciplinary collaboration among ecologists, biologists, and hydraulic engineers. These cooperative efforts are essential for mitigating the impacts of anthropogenic pressures on river habitats.The book features peer-reviewed versions of invited lectures and regular presentations from the 42nd International School of Hydraulics, held May 20–23, 2025, in Radocza, Poland. With contributions from leading experts and emerging researchers alike, it spans a broad spectrum of topics in environmental hydraulics, including sediment and pollutant transport, fluvial morphodynamics, hydraulic structures in rivers and reservoirs, and innovative measures for freshwater fish protection.
