Atlantropa was a geoengineering project to build a series of dams across the mediterranean sea to slowly drain it creating new land, satisfying the energy requirements of europe and even merging the subcontinent with Africa.

And a few images:
I have been considering something similar happening in my own narrative project as well, specifically by being part of the world's lore, though not as radically as the source material and definately not for the same reason.
The idea is essentially that in order to cope with raising sea levels and climate change (brought by their rampant industrialization and urbanization) the civilization inhabiting the tropical earth-like planet my project revolves around built dams and barriers to preserve/reclaim important lands across the globe while also exploiting tidal and hydroelectric energy to 'terraform' these lands to a useful, fertile state (through desalination of the water, the creation of artificial bodies of freshwater, while also synthesizing nutrients) and increasing their power over the world. One thing is for sure though, they'd not be brazen to the point that they'd actually dry bodies of water up.
Would such a drastic response would be warranted, sensible and feasible? Especially in the face of a serious climate crisis? And would it actually be beneficial?
Another real world reference would be this: https://en.wikipedia.org/wiki/Northern_European_Enclosure_Dam
Just so we are clear the civilization is very very advanced, akin to early to mid 22nd century humanity and have achieved advanced nuclear technology, quantum supercomputers and internet and are spacefaring (they have outposts across the solar system).
