Non CS Management Flashcards
1
Q
Hard engineering management
A
- rock armour
- groynes
- curved sea wall
- stepped sea wall
2
Q
Rock armour
A
- high cost
- lasts a long time
3
Q
Groynes
A
- ok cost
- lasts 50-70 years
- high maintenance costs
4
Q
Curved sea wall
A
- very high costs (millions)
- lasts up to 100 years
- refracts wave energy
5
Q
Stepped sea wall
A
- similar costs to curved sea wall
- dissipates wave energy
6
Q
Soft engineering management
A
- beach recycling
- beach re profiling
- beach replenishment
7
Q
Beach recycling
A
- LSD transfer sediment from A to B + then a truck transports sediment back to A
- low cost of
8
Q
Beach reprofiling
A
- change the shape of beach (create a steeper gradient) to make it less susceptible to erosion
- low cost of
9
Q
Beach replenishment
A
- sprays sediment directly onto beach from sea bed
- low cost
- high maintenance
