1 Strategic approach towards Post Tsunami Mitigation and Conservation of the Sri Lankan coastline Dr. S.S.L.Hettiarachchi Dr. S.P.Samarawickrama University of Moratuwa Illustrated via a Case Study for the Galle District Dr. N.Wijeratne University of Moratuwa Acknowledgements- USAID/IOTWS Project NSF, Sri Lanka WAPMERR, Geneva PARI, Japan Geo Science, Australia University of Arizona UNU, Bonn
2 Strategic approach in developing Early Warning and Countermeasures..for coast conservation, protection of lives, coastal ecosystems and infrastructure Multi Hazard Coastal Risk Assessment Framework. towards Disaster Risk Reduction Risk= Hazard x Exposure x Vulnerability x Deficiencies in Preparedness Mitigation Options Multi Hazard approach considers all coastal hazards, each having a frequency of occurrence and potential impact (intensity /spatial distribution)

6 Damage at the boundary of water bodies penetrated by the tsunami. Rail track severely affected. Damage to protection works and breakwaters in harbours
7 Impact on vegetation and coral reefs
8 Satellite Images Impact of the tsunami on the coastline. (South west coast of Sri Lanka)

10 Energy concentration at headlands and in bays depth Incoming wave rayscontours
11 Erosion and Deposition caused by tsunami waves Crest Trough Long waves of high amplitude
12 Tsunami Erosion and Deposition
13 Post Tsunami Scenario -Damaged reef and eco-systems -Damaged protection works -Increased bathymetry and changes in near-shore areas - -Waves of greater height close to the shoreline -Increase in coastal erosion due to the changes in the bottom bathymetry
14 2 Early Warning and Countermeasures against tsunamis Promote successful evacuation from tsunamis Early Warning System (Local and Regional) Public Warning System Hazard, Vulnerability and Risk Maps Set Back Evacuation Routes & Structures Mitigate tsunamis (Mitigation Options) Physical Interventions (Artificial Methods, Natural Methods and Hybrid Methods) Design Guidelines for exposed infrastructure Risk Assessment- Hazard, Exposure,Vulnerability and Deficiencies in Preparedness
15 3 Assessment of the Tsunami Hazard and Exposure Tsunami Generation from Earthquake at a Subduction Zone (1) Tsunami Hazard Source Exposure (2) Tsunami Hazard Impact on land Distribution of epicentres of earthquakes greater than magnitude 5.0 for the period , SE Asia- Indian Ocean (UNDP)
16 Tsunami Hazard Source Tsunami Hazard Impact on land Geological and Seismic Studies of the hazard sources Hydraulic and Geological Investigations of the impact of the tsunami hazard on land Probabilistic Tsunami Hazard Modelling (PTHM) Deterministic Tsunami Hazard Modelling
17 Exposure to the Tsunami Hazard on land at a given location Exposure of the island
18 Submarine Geological features Enhanced Exposure at a given location Impact of Submarine Geological features, Coastal Processes and Local Geometry on Tsunami Wave Amplification Regional Location Location with respect to the Continental Shelf Shoreline Geometry
19 Challenge (1) To study overall exposure of the island (2) Simulate tsunamis which have taken place and where possible, compare with field measurements on height, inundation and run up. (3) Simulate potential tsunamis based on Credible Scenarios obtained from Geological and Seismic studies of the hazard. Deterministic Tsunami Hazard Modelling Deepwater Modelling, Near-shore and Inundation Modelling

22 4 Tsunami Mitigation using Artificial and Natural Methods (1) Reduce the impacts of tsunami waves prior to reaching the shoreline Energy dissipator/ Partial barrier in coastal waters Overall Strategic Approach (2) Protect the coastal zone thus preventing the inland movement of tsunami waves Full barrier on the coastline (3) Mitigate the severe impacts of tsunami waves on entry to the shoreline Partial barrier on the coastline
