Oostende Sluice dock – Harbor project Partners VLIZ (=scientific PM): Hernandez F. & Cattrijsse A. MDK (=sponsor) : Bertheloot M. Elscolab (=installer) : Depauw P. YSI (=installer) Presentation by Hernandez Francisco,VLIZ
Oostende Sluice dock artificial lagoon intended for dredging (flushing) but never used as such later aquaplane landing place now : aquaculture of oysters sports windsurfing fishing bird reserve scientific research
Oostende Sluice dock mixed water intake freshwater from Noordede river effluent water from canal oostende-brugge seawater from harbour water quality problems eutrophication Ulva blooms sedimentation on edges of dock
Objective of the monitoring system Based on some real-time parameters and simple evaluation decide if the water of the sluice dock should be refreshed. decide if the water quality in the harbour is good enough to open the sluice doors. Data for scientific research
Oostende Harbour Overview Real-time Water Quality Buoys (x2) Real-time level and water quality station Salt water nutrients MET Water Quality Parameters GSM communication Powered by Solar energy Provided as partnership between YSI and Elscolab, Belgium
Project status Monitoring and data systems operational since 2006 Last buoy on location since aug 2007 Next fazes collect data at least 4 seasons analyse data modelling ?? alerting systems ??
Problems encountered so far Pressure of water very strong Sabotage, vandalism Cable in datalogger disconnected Cost of communication !! Bad coverage of telecom operator Harbour works, no room for bouy Reference level for water, sensor moved Detection limits for nutrients in winter to low Public tenders
