Abstract

This paper intends to describe how human pressure on Italian Alpine basins has been quite relevant for several centuries, in terms of land-use variations, in-channel structures, timber transport (splash damming) and riparian vegetation management, such that nowadays "reference conditions". In addition, recent natural climatic variations (e.g. the Little Ice Age) are superimposed on human disturbances, thus defying the definition of any "equilibrium" morphological conditions even under "human-free" states. A summary of works on historical channel adjustments in rivers of the Italian Alps is presented in order to document the impacts deriving from human pressure at different basin scales and for different river morphologies, from steep confined streams to large unconfined rivers. General options for river management and restoration actions aiming to combine geomorphological functionality and flood hazard mitigation are discussed
