    Abstract

    The impact of Flood Alleviation Schemes (FAS) upon rivers is under-researched due to, the focus predominantly residing upon the prevention of flooding, and the difficulties associated with measuring the effect FAS have on rivers. A case study of the River Ems, using GIS mapping and knowledge obtained during field work, shows that FAS have a significant impact on rivers. There are obvious positive impacts in the reduction of flood risk, however there can be various negative impacts, which are less recognised including, changes to the physical shape of the river, damage to the water quality and impacts on the ecology of the river system. Therefore this needs to be considered when producing FAS policy, which is currently uncertain, in the UK, due to the recurrence of flooding events across England since autumn 2000. It is clear, a balance needs to be met between, providing protection from floods and protecting the environment, this will change from river to river and therefore policy should consider individual evaluation of rivers rather than grouping them and applying one measure to reduce the flood risk.
