three common approaches to flood prevention Flashcards
1
Q
increase storage upstream therefore reducing discharge or runoff from the basin
A
e.g. dams like hoover dam
afforestation increases interception, Lake District
2
Q
Increase capacity downstream, thereby allowing more cumecs safe passage
A
reshape + straighten channel
dredge river bed e.g. boscastle
build extra channels to increase discharge capacity e.g. Jubilee river
3
Q
separate people from rivers, thereby reducing flood hazard
A
raise vulnerable building off the ground
strategic retreat
build drainage systems
