Offsetting sea level rise: An engineering idea of Biblical proportions

The seas are rising. Climate change has made it inevitable
. I have a strange question... Assuming that world sea-level rises by 1 metre over the next hundred years - Would it be possible to cordon off a section of land, somewhere in the centre of a continent, and flood it to create an artificial ocean, thus reducing the consequences of the sea rise?

This Biblical scale engineering feat must take these issues into account:
1. The section of land would have to be a very large 'bowl', in the centre of a continent, that is already below sea level. Another section of land, leading from the ocean to this central 'bowl' section, would have to be carved out to create the biggest dam system mankind has ever witnessed. Does somewhere like this exist?
2. The number of humans currently living in this 'bowl' would have to be less than the number of humans who would be displaced by the 1 metre sea level rise. Otherwise this huge engineering feat would not be worth undertaking.
3. Other environmental issues should be taken into account, such as the ecosystems that would be displaced or the new weather patterns and ocean currents that would be created.
Do you have the calculations of water/land displaced? Or ideas about where this kind of thing could be built? I'd love any input on this monstrous thought experiment.
