Resilience measure: Filled container


These are cellular barriers filled with aggregates or water to form a barrier against floodwater. Containers can be divided into two categories, permeable and impermeable. In both cases, they serve as gravity dams, using the weight of the aggregate or water for stability. These containers are another example of temporary flood protection systems. Filled permeable containers are cellular barriers made of permeable materials such as geo-textile or geosynthetic fabrics and filled with aggregates to form a barrier against floodwater. Some containers are strengthened and held in place by wire meshes, pins and frames. On the other hand, filled impermeable containers are made of impermeable materials such as polyester, polyethylene and plastic. The containers themselves are impermeable and are filled with water or aggregates only to provide additional weight. These systems are gravity structures achieving stability through their weight and shape (Ogunyoye F. et. al, 2011, p. 41).

Co-benefits and impacts

As an application/example of temporal flood protection system, they are quickly and easily placed and removed, efficiently stored and easily transported. The advantages of filled permeable containers are: the height of some systems can usually be increased during service by stacking; can usually be installed by relatively unskilled larbour; small storage space required; adapts to uneven formation/terrain and can use readily available fill material, whereas the filled impermeable container does not rely on fill material for water tightness and in or repairs to tears or punctures can usually be made in service.
