Building houses in flood risk areas has caused residents and local councils to see rivers as "The Enemy." I hardly need add that this is usually the fault of the councils involved; especially those where there are families of builders wielding a maffia like control on such councils.
Seeing the damage that has been caused in the past by river floods is now being visited on the older properties, built in areas where floods never used to occur, what limit is there to the need for flood barriers?
