Flood walls are engineering structures built parallel to a body of water to prevent flooding. Understanding their impact involves looking at both the positive outcomes they offer and the challenges they present.
Based on information from FEMA, flood walls serve as critical components in flood mitigation strategies, providing significant protection but also introducing potential issues.
Flood walls offer a primary advantage by directly reducing the impact of flood events. However, their implementation is also associated with several drawbacks that need careful consideration.
Here is a breakdown of the advantages and disadvantages of flood walls as outlined by FEMA:
Advantages of Flood Walls | Disadvantages of Flood Walls |
---|---|
Reduces the physical, financial, and emotional strains that accompany flood events. | May affect local drainage, possibly resulting in water problems for others. |
Does not reduce flood insurance premiums. | |
May restrict access to structure. |
In summary, while flood walls can greatly alleviate the direct hardships caused by flooding by protecting areas behind them, they may also inadvertently impact drainage patterns elsewhere, do not lead to lower flood insurance costs, and can sometimes hinder access to protected buildings or areas.
