Sediment yields in 11 river catchments in North-Western Greece are computed with the application of the mean daily discharges to the sediment discharge rating curves and compared to the earlier estimates published by other researchers. For these catchments a number of hydrologic and geomorphologic parameters have been computed using advanced mapping methodologies. An attempt is made to correlate the suspended sediment estimates mainly with geomorphologic parameters, that rarely has been carried out in the international literature. Key words: sediment yield, hydrology, geomorphology, Western Greece. ι ι ιι υ ι υ υ υ ι υι ι ι υ, 11 ι υ ιυι . ι ι υι ι ! υ! – .
