What is an alternative flood management method, such as planting trees, creating floodplains, or importing beach material?

• A. Source
• B. Recharge
• C. Soft engineering
• D. Sediment

Answer: (C)

Soft engineering covers flood management methods that work with natural processes rather than through built barriers. Planting trees, restoring floodplains, and beach nourishment by importing material all slow, store, or divert floodwaters in natural ways and often bring ecological benefits. The other terms are hydrological concepts rather than management approaches—source refers to where water originates, recharge is groundwater replenishment, and sediment means the material carried by water. So the best answer is soft engineering.
