The influence of core permeability on armour layer stability

This study describes a theoretical approach of a physical description of the notional permeability factor in the stability formulae of Van der Meer [1988]. Caused by the empirical character of these stability formulae a physical description is not available for the notional permeability factor. In practice this leads to ambiguities in...

Fieldwork coastal engineering: Preliminary design of a floating marina, Varna, Bulgaria

The beach in front of the hotel Sirius is suffering from a retreating coastline. Bathymetry and beach profiles were measured. With the data from previous years the long term evolution of the coast was analyzed. The main conclusions were that the beach in front of the Sirius hotel is still suffering from erosion and if this erosion trend...
