This paper presents 2 new definitions of sediment and water flux connectivity (from source through slopes to channels/sinks)with examples of applications to sediment fluxes. The 2 indices of connectivity are operatively defined, one (IC) that can be calculated in a GIS environment and represents a connectivity assessment based on landscape's information, and another that can be evaluated in the field (FIC) through direct assessment. IC and FIC are based on recognized major components of hydrological connectivity, such as land use and topographic characteristics. This procedure has been applied in a medium-size watershed in Tuscany (Italy) with the aim of evaluating connectivity, identifying connected sediment sources and verifying the effects of mitigation measures. The proposed indices can be used for monitoring changes in connectivity in areas with high geomorphological or human induced evolution rates
