River Morphology deals with the interaction between flowing waters in rivers and their environment. Based on the representation of basic flow parameters, the geometry, classification and historic development of rivers are treated. Any change in the environment, occurring naturally or caused by man, leads to very sensitive reactions in river flow and transport. Thus this synopsis of geoscientific studies and hydraulic engineering experience is presented to help develop the unterstanding of how to handle nature with care.
