In the scenario where the water level exceeds the barrier’s capacity, several consequences can arise. Here’s what can happen and how precautions can be taken:
- Increased Seepage: If the water level surpasses the barrier’s designed capacity, there might be an increase in seepage.
- Overtopping: Water overtopping occurs when the water level rises above the top of the barrier, causing water to spill over the barrier’s edges.
- Risk of Sliding: In situations of water overload, there’s a potential risk of the barrier sliding or shifting slightly, particularly if the equilibrium between water pressure and barrier stability is disrupted.
It’s important to note that the barrier is designed with safety considerations in mind. Even in cases of overtopping or water exceeding the barrier’s capacity, the barrier will not suddenly collapse and endanger people or critical infrastructure. Only if water overflows and continues to fill up on the other side of the barrier the equilibrium will eventually be affected, and the barrier can in the worst case slowly slide a little.
To address potential water overload scenarios, precautions can be implemented. If the water level rises significantly, several measures can be taken to enhance the barrier’s stability and mitigate the risks:
- Extra Tubes: Adding another Flood Barrier behind or on top of the existing tubes can provide extra support and weight to counteract the force of the water.
- Sandbags: Sandbags can be strategically placed on top (1) of the barrier to add weight and prevent overtopping. Additionally, sandbags or bigbags can be positioned behind the barrier to offer additional support (2).
In summary, while water overload can lead to increased seepage, overtopping, and risk of sliding, the Flood Barrier is designed with safety and stability in mind. Precautionary measures such as adding extra tubes or sandbags can enhance the barrier’s performance and provide a safeguard against potential challenges caused by water exceeding its designed capacity.
