Personally i don't think that flood defences are bad for the environment, pollution is more damaging to the environment then flood defences, but that is just opinion
different types of flood defences
Things like building sand bags and dikes are flood defences.
An embankment could mean a raised bank along a river as part of flood defences.

No, the area drained by a river is a river basin or drainage basin. The flood plain is in the lower valley reaches, where heavy rain can cause the river to flood, often bursting over flood defences, and for the water to flood over a large area.
Roads, buildings, canals, dams, railways, tunnels, flood and coastal defences
The effects of flooding can be reduced by implementing flood management strategies such as building flood defenses, constructing sustainable drainage systems, preserving natural floodplains, and limiting development in high-risk flood areas. Additionally, early warning systems, flood insurance, and community education on flood preparedness can help minimize the impact of flooding.
Because of the Boscastle Flood, the village of Boscastle had to pay millions of pounds for repairs and defences for future floods. One family alone had to pay thousands of pounds because their home, car and possessions were totally destroyed.
It happen because of us humans are bad to nature, nature is flood and flood is nature. If we haven't been bad to nature, there wouldn't even have natural disasters around the world.
