How dam installation reshapes river geomorphology

Seeing how mangrove forests protect coastal cities is so damn cool too.

Not at all how a dam works

Dam, that’s interesting

What is the song called that starts at :37 ?

How does it affect the fish?

Dam that’s crazy

How does dam installation affect the river's shape?

These are called "low head" dams in midwest USA they were installed in small rivers and large creeks for flood control but almost all will be removed to restore nature and eliminate unseen flow obstructions for recreation (canoeing)

You can even how the "drowning machine" formed as it reshapes.

I thought that was some microorganism under a microscope until the hand appears.
