| Muddy shore backed by sediment plain - potential vulnerability to change including erosional recession |
| Muddy shores backed by harder bedrock - limited potential vulnerability to erosion, depending on backshore bedrock type |
| Open sandy shore backed by soft sediment plain - potential erosion and shoreline recession vulnerability |
| Open sandy shores backed by bedrock - potential beach erosion, lesser recession vulnerability |
| Re-entrant sandy shore backed by bedrock - potential beach erosion, lesser recession vulnerability |
| Re-entrant sandy shore backed by soft sediment plain - potential erosion and shoreline recession vulnerability |
| Undifferentiated sandy shore - potential erosion vulnerability, type unclassified |
