Discuss below given diagram about flood problem in uk town

The blueprint of UK Town illustrates about how flood cause problem for factories, residential park and commercial plaza along with two solution. Overall, Flooding became serious issue for dwellers so to answer that conundrum two solution like damming to maintain flow of water and reallocation space for building and parks has been introduced. However, both of them have their own merits and demerits. On the one hand solution one is about demolished current parks and residential area which are suffering through river overflow and reconstruct them little far from river b. but it is really expensive to move businesses and houses. However, it is more environment friendly On the other hand damming to control river flow is second solution. And it suggests that one dam would be constructed on the east side of river B whereas second dam would be constructed on the north side if river A instead of relocating properties but it has one minus point that it would preserve land.
