The measure resulted in less effort and therefore a cost reduction for the harbor administration, i.e. for maintenance dredging and disposal of contaminated sediments. Further, reliable water depths made planning and disposition easier for local companies.

Expected effect
From 1991 – 1996 the sedimentation rate in the harbor basin was monitored and compared to the sedimentation rate that took place before the wall was built. The measure was considered to be successful: per year 50% less sedimentation occurred in the entrance of the basin. At the end of the basin no reduction of sedimentation could be observed and no additional sedimentation in the neighbor basins took place.The measure resulted in less effort and therefore a cost reduction for the harbor administration, i.e. for maintenance dredging and disposal of contaminated sediments. Further, reliable water depths made planning and disposition easier for local companies.
