River flow 2012

Rivers are complex entities. In addition to being valuable habitats for wildlife, they support human activities by providing water for human use, renewable energy and convenient transportation. Rivers can also pose threats to riverine communities, in the form of floods and other natural or human-induced hazards.

Contemporary societies recognize their responsibility to ensure the sustainable use of rivers and to preserve the intrinsic ecological and landscape values ​​of the river. This commitment often conflicts with economic exploitation of the river and with concerns for risk management. As a discipline, river hydraulics makes a significant contribution to the development of sustainable river use strategies by providing new modeling tools and engineering techniques based on advances in phenomenological understanding and computational modeling.

River Flow 2012 is the proceedings of the 6th International Conference on River Hydraulics, organized under the auspices of the River Hydraulics Committee of the International Association for Hydrological Engineering and Research (IAHR). The book addresses issues such as river hydrodynamics, morphodynamics and sediment transport. Other contributions describe interdisciplinary approaches and experiences, particularly in relation to cross-cutting activities involving environmental science and information technology. River Flow 2012 contains the latest theoretical achievements, numerical developments, experimental investigations, and field studies in river hydraulics. It is an excellent resource for researchers, civil and environmental engineers, and practitioners in river-related disciplines.
