Flooding can result in significant damage to the environment along with economy, property & infrastructure. Flooding can be caused by small watercourses, direct surface runoff. Apart from all these the oceans along with rivers below the ground drainage systems are also taken into consideration. There are numerous types of flood defenses that have been developed over the years to protect against flooding. The managing of flood risk & the development along with the implementation of flood control system has a lot of advantages.
Costing- While flood defenses can be effective at protecting properties & resources, they can also be expensive to install & maintain. For instance, a 4-foot section of sea wall generally consists $10,000. If this sea wall can prevent millions of dollars in damage each year!! However, if the respective area is not prone to flood damage, the cost may be justified.
Protection- Numerous types of flood defenses like sea walls, offshore bar and rock. It offers significant protection to the cost-line in particular. In particular, they can deflect waves that absorb the wave energy & it protects the base of cliffs & stop beach erosion.
This temporary water dams protect your home in the heavy flood zones. It decreases the rate of erosion, preventing foundation & structural damage in the long run. They also save a lot of money in terms of roadway infrastructure.
Natural Habitat- While flood defences do protect homes, roads along with cities they also offer protection to natural habitats. Many shorelines are conservation areas & flood defences help preserve these areas. Several types of flood control systems mainly those that are classified as natural systems, promote diversity.
It is the wetlands that functions at flood plains that support a wide range of birds while ponds support newts along with leeches, wading birds.
Economic advantages- While flood defenses are expensive to construct & maintain. There are several economic advantages to be had. By establishing flood plains & wetland systems to divert flood waters latest economic possibilities can develop. Wet lands also play important role in water resources as these areas store & filter water pollutants. When the flood plains are not full of water, they can grow grass & can be used as grazing areas.
