River Flow 2006, Two Volume Set: Proceedings of the International Conference on Fluvial Hydraulics, Lisbon, Portugal, 6-8 September 2006

With contributions from an international team of experts, this book covers issues such as river hydrodynamics, morphodynamics and sediment transport. Other contributions describe interdisciplinary approaches and experiences, particularly regarding interfacial activities involving environmental sciences and information technologies. River Flow 2006 contains the most recent theoretical accomplishments, numerical developments, experimental investigations and field studies in Fluvial Hydraulics. It is an excellent resource for researchers, civil and environmental engineers, and practitioners in river-related disciplines.
