Ship-induced erosion along the Kiel-Canal

摘要

The classification of ship-induced erosion along the Kiel-Canal shows that about 80 ％ of the canal's bed is threatened by traffic-induced streaming. The shear stress and the excess pore water pressure have been described in three limit states from which the classification was built of. The current velocity was determined basing on formula of Manning-Strickler and then expressed as shear stress. This could be put into formulas of moved sediment to calculate the erosion mass.
