A barrier apparatus comprises one or more barriers 10, the or each barrier comprising a wall member 20 having first 22 and second 24 ends, and being pivotably mountable at a location 26 interposing the first and second ends. A first portion 30 of the wall member on one side of the pivot point 26 is pivotable from a substantially horizontal orientation 100 to an upwardly extending orientation to provide a barrier. A second portion 32 of the wall member on the opposing side of the pivot point is pivotable from a substantially horizontal orientation to a downwardly extending orientation to cooperate with a stop member to provide supporting means. The first portion of the wall member may be substantially longer and lighter than the second portion of the wall member. The wall member pivots from a dormant horizontal orientation to a substantially vertical flood protection orientation in response to rising flood water. |
