The principle behind the confirmed Flood Prevention Scheme is one of catchment management.

This will involve the formation of three flood storage areas upstream of the city to temporarily hold back the bulk of floodwater generated by extreme rainfall and control the release of water passing downstream through the city to an acceptable level.

Although during the storm, the temporary storage areas will significantly reduce the flow downstream, this much reduced flow, combined with the large catchment area downstream of the flood storage areas will still pose a threat and be capable of causing flooding in Glasgow. For this reason, flood defences, in the form of low walls and embankments, will also be constructed in selected parts of the river corridor through the city.

These works will also afford opportunities for environmental enhancement along the river corridor and around the storage sites.
