Land-use planning includes _________ or ______________ building in floodplains and ensuring that new infrastructure projects consider flood risk in their design and location

PREVENTIVE AND MITIGATION MEASURES

A

restricting
prohibiting

28
Q

Increase the flow capacity of a river

30
Q

serves as barrier when water significantly goes high

PREVENTIVE AND MITIGATION MEASURES

A

Construction of dikes and levees along rivers or streams

31
Q

Precautionary measures and actions are stated for residents to take (moving to higher places, electric-operated appliances should secured to higher places)

32
Q

is the movement of a mass of rock, earth, or debris down a sloped section of land.

A
