AB: River networks and the transport processes that take place in them provide a natural integrating framework for the hydrologic,ecologic,and geomorphologic dynamics that take place in river basins.The profound commonalities existing among all types of river basins and their drainage networks,together with the key role that these dendritic structures play in the above dynamics encourage the search for general type of statistical signatures in a variety of phenomena realted to the above intertwined dynamics. We identified the main sources of complex behaviour associated with dendritic lanscapes,relate them to the structure of the channel network and its transport characteristics and explore how these affect the patterns and dynamics of the complex systems of hydrologic,geomorphologic,and ecological character associated with them. The statistical signatures of alpha,beta,and gamma biodiversities of riparian vegetation are studied as well as the structure of the spatial organization of the vegetation in the basin.
