The risk of flooding is defined as a function of both the probability of a flood happening and its impact. In urban areas, the impact can be very high because the areas affected are densely populated and contain vital infrastructure. The reason for increased flooding in urban areas is twofold. Firstly, increased urbanisation has resulted in developments encroaching on floodplains, obstructing floodways and the loss of natural flood storage. Secondly, increased urbanisation has resulted in increased impervious areas such as roads, roofs and paving which create more rainwater water run-off.
To establish the flood risk associated with individual sites or catchments PUNCH Consulting Engineers can undertake Flood Risk Assessments in conjunction with River Flow Modeling.
PUNCH Consulting Engineers recognise that the Sustainable Urban Drainage System (SUDS) approach to drainage reduces flood risk, minimises diffuse pollution, maintains or restores natural flow regimes and improves water resources while enhancing amenity. PUNCH have varied and extensive experience in the design of SUDS systems.
