Flood control measures in Manipur might include:

Embankments
Dams and reservoirs
Watershed management
All of the above

The correct answer is: All of the above.

Embankments are artificial barriers that are constructed to prevent flooding. They are typically made of earth, stone, or concrete, and they can be either natural or man-made. Embankments can be used to protect areas from flooding, such as towns, cities, and agricultural land.

Dams and reservoirs are also used to control flooding. Dams are constructed across rivers to create reservoirs, which can store water during periods of high rainfall. This water can then be released slowly during periods of low rainfall, helping to prevent flooding.

Watershed management is a process that is used to protect and manage water resources. It involves a variety of activities, such as land conservation, forest management, and flood control. Watershed management can help to reduce the risk of flooding by preventing soil erosion and runoff.

All of these measures can be used to control flooding in Manipur. The most effective approach will depend on the specific circumstances of each area.
