- Hard Engineering
- Sea walls - concrete walls that are placed (expensive but effective)
- Rock armour - boulders at the bottom of cliffs to get most of the impact (expensive to transport but cheaper than sea wall)
- Groynes - wooden or rock structures built at an angle to the sea (unattractive but builds beaches
- Soft Engineering
- Beach Nourishment - placement of sand onto beach to build it up (constant replacement but blends with existing beach)
- Same erosion processes as coast
- Same transportation as coast
- Watershed - area of high land forming the edge of a river basin
- Source - where the river begins
- Mouth - where a river meets the sea
- Confluence - where two rivers meet
- Tributary - small river or stream that joins a larger river
- Channel - where the river flows
- Long Profile - view of river from source to mouth - upper course, middle course, lower course
- Cross Profile - cross section of a channel or valley
- Vertical Erosion - eroded downward
- Lateral Erosion - eroded lateraly
