Flow in a channel with a mobile bed is usually accompanied by a transport of sediments; erosion and deposition might be the consequence. Additional erosion of sediments will be caused, where there is a local change in the geometry of the channel or in the

Preface
River management is a big challenge of the twenty-first century for the scientific community associated with water resources. River basins are complex systems. They are open systems with sometimes ill-defined boundaries. It refers to various aspects essential to achieve a sustainable development of river basins, including water demand and river management. Rivers may have shared delta, watershed limits in flatland areas are either vague or man-made (and alterable), and watershed limits often do not correspond exactly with aquifer limits. On top of this, river basins interact continuously with the atmosphere (precipitation and evaporation, airborne pollution) and the receiving waters (seas and sometimes lakes). Furthermore, the uses made of river basins often transcend river basin boundaries (e.g. interbasin water transfers) as well as political borders of countries. Rivers are important as they fulfil many important functions, such as water supply for households, industry and agriculture, navigation, fishing, recreation and ‘living space’. Economic and social development and even life itself cannot be sustained without sufficient water at the right time and place and of right quality. Integrated river management is about all these things. It is much br
