Sommario/riassunto

Ecohydraulics: An Integrated Approachprovides a research level text which highlights recent developments of this emerging and expanding field.  With a focus on interdisciplinary research the text examines:- the evolution and scope of ecohydraulicsinteractions between hydraulics, hydrology, fluvial geomorphology and aquatic ecologythe application of habitat modelling in ecohydraulic studiesstate of the art methodological developments and approachesdetailed case studies including fish passage design and the management of environmental flow
