Characterisation of harbour and coastal sediments: specific destinations of dredged material
Abstract Most sediment dredged in Italian harbours is discharged into coastal areas. Italian legislation provides physical and chemical characterisations of dredged material.

Abstract Most sediment dredged in Italian harbours is discharged into coastal areas. Italian legislation provides physical and chemical characterisations of dredged material.
