When wetlands are paved over there could be flood around/near that area because when it rains hard wetlands soak water and the kind work as a filtering system. As mentioned above that wetlands soak water when it rains, well when they are paved over cement/concrete don't absorb the water. So there are chances that when it rains really hard in that area it might be flooded.
Nothing major would happen. Dolphins are not an extremely important part of society. Sure, sea worlds wouldn't be as fun, but nothing major would happen.
Some archaeologists may become very upset.
