Abstract:

The drying of dredged material was modeled mathematically as a diffusive process and the governing equation was solved using an integral method. Closed form solution equations are presented which allow calculation of drying progress during both the constant-rate and falling-rate periods for both thin and thick layers of material. The moisture diffusivity, a material property, was determined experimentally and used to model dredged material drying in the laboratory under controlled conditions.
