Nowadays it is increasingly hard to deny that climate change is real and factors largely in recent floods. A recent study in Western Europe, for instance, shows that floods like the one in Paris in January 2018 are rising because of global warming. The United States has its share of flood-prone areas, such as New Orleans during Hurricane Katrina in 2006. Thanks to engineering, here are five steps that can be taken to help prevent flooding in these populated areas.
Water Storage Facilities
Water storage facilities can collect rainwater and store them for use in fire suppression, raising livestock, and irrigation for farming. Instead of unnecessary flooding, water storage gives purpose to rainwater.
Erosion And Sedimentation Control
In doing constructions to prevent flooding, soil gets disturbed. If left unattended, the rain might wash off this soil and cause erosion. Erosion and sedimentation control means you have to protect this soil by quickly providing vegetation to stabilize it and similar measures.
Flood Control Structures
Flood control structures are built in areas where there are risks of flooding such as dams and floodways. These structures are crucial especially if there are communities near these dams or floodways.
Culverts are structures that let water flow underneath a road or trail from one side to the other. A box culvert is one with four sides, designed specifically to convey or carry storm water, sewage, and such.
Channel relocations are made when you physically alter creeks, rivers, or similar bodies of water into a new path or channel. This is done to divert water from one area to another to prevent flooding. These five steps are examples of how engineers help you with flood control management, be it in New Orleans or Houston.
