Detailed explanation-1: -Which is mostly likely a prevention strategy for flooding? Building artificial levees. How could the removal of trees and other vegetation impact on the environment? By increasing erosion.
Detailed explanation-2: -Levees work by providing a physical wall or barrier through which water cannot permeate in the event of a flood, thereby protecting land, property, wildlife, and people.
Detailed explanation-3: -Why are artificial levees only useful for some flooding events? Levees cannot be built larger than the surrounding floodplain. Flash floods occur too quickly for officials to close the levees. Levees are built in rural areas and will not help for flooding in the city.
Detailed explanation-4: -The rapid response water-gate in the US A device known as the water-gate can be a useful alternative. This is a rapidly deployable device made of a PVC material. It utilizes the pressure of oncoming water to stabilize itself. This essentially means that the floodwaters are used to build their own dam.
