===Public safety===

===Public safety===

Where temporary storage of water occurs on the surface, the depth and rate of rise of the water should be sufficiently low that risks are minimized for site users, especially since the temporary nature of the storage facility will mean that the public are not accustomed to its presence. A risk assessment should be undertaken of the frequency and rate of flooding to a range of inundation depths in order that public safety is not jeopardised (Ballard et al., 2015). <ref name=Ballard>Ballard, B.
