Relevance of GIS (Geographic Information Systems) in mitigating oil spill hazards

1. OIL SPILL HAZARD AND GEOGRAPHICAL INFORMATION SYSTEM (GIS) M46GED Concepts and Models of Environmental Hazards COVENTRY UNIVERSITY Department of Geography, Environment and Disaster Ukueku Kevin January 2009

3. INTRODUCTION

7. CONCEPTS OF RISK FOR OIL SPILL HAZARD

8. Risk is the probability of a hazard occurring and creating loss and Hazard is a potential threat After Keith S. (2004). Hazard is the occurrence probability After Cole P. (2008)

10. Part of a data base

11. Event tree Boyka S. et al (2004)

13. Risk in terms of vulnerability is Risk = Hazard × Vulnerability × Value Where, Value is the inventory of an element(say fish) in a coastal environment and After Cole P. (2008)

15. Vulnerability index for coastal environments (Gundlach and Hayes 1978)

16. In recent times, vulnerability Index ( VI ) is known as Environmental Sensitivity Index ( ESI ) that is; VI = ESI

17. 3. OIL SPILL HAZARD AND GIS

18. GIS is a powerful tool for the Modelling , Monitoring and Mitigation of oil spill hazard.

21. GIS FOR MONITORING Its integrating ability is a very powerful tool for the effective monitoring of oil spill hazards.

22. A Bathymetric map of the Norwegian coastline showing the drift of spilled oil within a 6 hour period in different colours

24. GIS FOR MITIGATION; Areas where chemical dispersants should be applied in the month of April in the event of a spill

26. The Australian OSRA OILMAP/GCOM3D output overlaid over a satellite image showing the locations of significant sea bird colonies After Trevor G. (1998)

29. 4. Advantages of GIS over other methods
