5. “deliver a safe (or low-risk) coast for human use/development and healthy coastal habitats as sea levels rise and climate changes and the European economy continues to grow” Aim

6. THESEUS baselines

7. Novelty? 1.S-P-R-C 2.Linkage: engineering – ecology – socio-economics 3.Decision Support Software

19. Flood maps (long-term conditions – RP 1/200)

20. Habitat Map

21. Habitat Teign Estuary Sections A, B and C represent different hypothetical habitat types. Scenario 1 shows no change in area for each habitat type under an elevated sea level. Scenario 2 shows that the area for all habitat types is reduced under an elevated sea level. Scenario 3 shows that the area of habitat type C is increased under elevated an elevated sea level. Interaction between sea level rise and topography and the potential implications for habitat types.

22. Ecological enhancement Shaldon flood defence scheme
