Typology and water bodies

5. Typology All countries use system B
Mandatory + all optional factors (§ 3.5)
Discuss and identify (common) types

6. Type factors Salinity (m) Tidal range (m) Wave exposure (o)
Substratum (o)
Current velocity (o)

7. Results 8 coastal water body types
3 to 5 transitional water body types

8. Boundaries Coast - transitional Transitional – river
Physiographic feature, salinity gradient
Transitional – river
Sluices, tidal limits, locks
Transitional – land
Dykes
Coast – coast
Typology, barrier
