Abstract:
A furlable fluid barrier section (1) comprising:a fluid barrier sheet (2) for preventing the flow of fluid across ground, comprising lower and upper edges; an apron (4) that is fluid impermeably connected to the lower edge of the fluid barrier sheet (2) and extending from the lower edge in a direction facing the flow of fluid wherein the fluid barrier section (1) is free standing when ready for use, support means for holding the fluid barrier sheet (2) above the ground at an angle over the apron (4) to define an open structure which is adapted to receive the flow of fluid, wherein, in use, the weight of the fluid on the apron (4) provides a downward force on the apron (4); tie means (10) adapted to connect to the upper edge of the barrier sheet (2); and a tie anchorage (11) adapted to connect the apron (4) to the tie means (10); wherein the apron (4), the tie means (10) and the barrier sheet (2) form a triangle in the transverse cross-section of the barrier section (1) when erected.
