Table 2 The coastline classification system and their description
From: Coastline carrying capacity monitoring and assessment based on GF-1 satellite remote sensing images
First classification | Second classification | Description |
|---|---|---|
Natural coastline | Rocky coastline | Bed of tidal zone is rock, it formed a curve coastline of harbor and cape by sea level rising and long process of marine hydrology. |
Sandy coastline | Bed of tidal zone is sand and gravel, the particle size of sand and gravel is 0.063–2 mm, it formed relatively flat coastline by long-term action of waves. | |
Silt coastline | Bed of tidal zone is silt with particle size 0.01–0.05 mm, it formed open coastline by the long-term interaction of waves and runoff. | |
Estuary coastline | It is located in estuary and is boundary line of river and marine. | |
Artificial coastline | Port coastline | It is vertical artificial dikes connecting deep water in port |
Industry and town coastline | It is a slope dam connecting industry or town and formed by reclamation. | |
Dam coastline | It is a dam located above the highest tidal line to prevent waves, storm tide, and other erosion. The near region of the dam is nature landscape, usually. | |
Pond coastline | It is a simple dam for aquaculture, sea salt, and other human activities. |
