coastal management
1. revetment: parallel struc to the shore, expensive, more for short term defence
2. seawall: mostly the same as revetment just that they look diff.
3. groynes: perpendicular to the shore, extend from the beach to the sea, ugly
4. beach replenishment: addn of sand to the beach, constant maintenance
5. breakwater: three hundred feets offshore (relative shallow water), subject to damage
no management? no beach..

squatter settlement
reason:
migration: no skills- no money- build temporary houses with any usable materials - squatter
features:
usu. along rivers, on steep hillslopes, under bridges or near transport routes (railways), on any vacant spaces (usu. at e edge of the city)
unventilated, lack of basic services (water, sanitation and healthcare), poor disposal systems, inadequate drainage system, overcrowded
problems (12):
1. lack of clean water
2. pollution (waste)
3. disease outbreak
4. prone to fire
5. prone to flooding
6. prone to landslides or soil erosion
7. child labour
8. high unemployment rate
9. high crime rate
10. segregation
11. lack of electricity
12. lack of healthcare
solution....... self help schemes (Rio de Janeiro)
why no use!!
1. govt: large expense to relocate them
2. just too many of them
3. they are unwilling (no money and far away from work place)
4. strong community spirit
yaaa........ done
