| Deltas |
3-dimensional features found where rivers that contain much sediment flow into the sea; velocity is reduced and deposition of material occurs. |
| Estuaries |
Where fresh water (rivers) and salt water (sea) interact. |
| Accurate estuary |
Rounded, convex edges. |
| Cuspate estuary |
Material evenly spread from the river. |
| Birds foot estuary |
Spread over a wide area with many 'distributaries' extending out to sea. |
| Bottom set bed |
Have finest material, carried furthest in suspension and sinks to sea bed. |
| Foreset bed |
More readily deposited, coarser material. Builds out to sea. |
| "top"set bed |
Deposits from river with the most coarse material. |
| Negative change |
A fall in sea level in relation to the land. |
| Positive change |
Sea level rises in relation to the land (or land sinking in relation to the sea). |
| Isostatic change |
Local changes in sea level, due to ice weight depressing earths crust lying beneath it. |
| Eustatic change |
Large scale/worldwide changes. |
| Rias |
Drowned river valleys. |
| Fjords |
Flooded U-shaped valleys. |
| Fjards |
Glaciated lowland areas that have since been flooded. |
| Raised beaches |
Landforms that occur due to isolated uplift of the land in comparison to the sea, as the weight of ice is slowly removed. |
| Hard engineering |
Structures that try to limit the impact on waves and their energy on a stretch of coastline. |
| Soft engineering |
More environmentally friendly - tries to work with natural processes to reduce, rather than prevent erosion. |
| Managed retreat |
Nature is allowed to take its course. Sometimes seen as the do nothing approach. |
