FURTHER REMARKS ON A DISTRIBUTED APPROACH TO SEDIMENT DELIVERY

In this paper the sediment delivery relationship, i.e. the relationshi p between the basin sediment delivery ratio SDRw and the sediment deli very ratio SDR, of each morphological unit, i, into which a basin is d ivided, is firstly tested using morphological data (length, steepness and area of each unit) from six Sicilian and three Calabrian basins. T hen a coefficient a of the sediment delivery relationship is related t o several channel network parameters affecting the sediment transport efficiency. Finally, the spatial distribution of Cs-137 activity measu red in a small Australian basin is used for validating the predictive capability of the proposed distributed approach to sediment delivery.
