1 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

2 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

3 Sluice dock users

4 Sluice dock bathymetry

5 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

6 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

7 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

8 Installations

9 Parameter Overview Water Quality Dissolved Oxygen pH Turbidity Chlorophyll Underwater PAR Temperature Conductivity Salinity Vented Level

10 Parameter Overview MET Wind Speed / Direction Relative Humidity Air Temperature Barometric Pressure Solar Radiation

11 Parameter Overview Nutrients Nitrate Phosphate

12 Systems overview EMM2000 buoy platform Campbell Scientific CR1000 data logger Systea NPA nutrient analyser YSI 6600EDS Multiparameter Sonde

13 Data acquisition GSM / GPRS and ADSL communication Loggernet = Campbell scientific software PHP scripts for database entry SQL database Interactive website : php php

14

15 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 ??

16 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
