What is building a dam or levy to control flooding?

Answer 1

Building a dam or levee to control flooding involves creating a barrier that regulates water flow in rivers or lakes to prevent overflow during heavy rain or snowmelt. Dams store water in reservoirs, allowing for controlled release, while levees are embankments built alongside waterways to keep floodwaters at bay. Both structures aim to protect nearby communities, agricultural land, and infrastructure from flood damage. However, they also require careful planning and consideration of environmental impacts.
