Answer 1

Explanation :

I am starting with intro of answer

Floods are the deadliest, costliest and most common form of natural disaster in the United States and in the world. They are caused by hurricanes, heavy rainfall, overflowing rivers, broken dams, overfilled urban drainage basins, tsunamis, water channels with steep sides, and ice- or snow-melt. Floods are difficult to predict, which means states must be prepared to respond at all times..... Flood mitigation approaches fall into two categories—structural and nonstructural. Structural forms of mitigation mitigate harm by reconstructing landscapes. They include floodwalls/seawalls, floodgates, levees, and evacuation routes. Nonstructural measures reduce damage by removing people and property out of risk areas. They include elevated structures, property buyouts, permanent relocation, zoning, subdivision, and building codes. Structural solutions have lost popularity over time as old dams and floodgates have failed.

that's all dear

Answer 2

Answer:

In environmental engineering, the flood mitigation involves the management and control of flood water movement, such as redirecting flood run-off through the use of floodwalls and flood gates, rather than trying to prevent floods altogether.
