Floods are among the most destructive natural disasters, often leading to significant property and life damage and major investments in water damage removal. Flooding can happen anytime or any place at any given moment; however, certain regions tend to experience flooding more frequently. Let’s explore four common areas prone to flooding and how floods occur within each one.
Floods may begin in many different ways. One common means is through heavy rainfall that causes rivers and streams to overflow their banks; melting snow/ice may also contribute to flooding; areas with heavy snow accumulation during the winter can see increased risks due to melting snow/ice melting into bodies of water, while dam failure or levee breaches could create catastrophic flood damage as a cause.
Cities are particularly susceptible to flooding because of their built environment. Urbanization creates many impervious surfaces like concrete, asphalt, and rooftops which stop rainwater from seeping into the soil instead of flowing off into storm drains and canals during heavy rain events - leaving storm drains overwhelmed and canals overwhelmed with too much rainwater for proper drainage.
Urban drainage systems need to be updated and adequately equipped to manage flood waters effectively, leading to flooding of stormwater and sewerage systems that cause significant property damage and health hazards for nearby residents. As a result, backup of this material leads to physical and health consequences for surrounding residents.
Urban areas at risk from flooding should seek to upgrade their drainage systems and decrease impervious surfaces by improving drainage, and installing rain gardens or bioswales for collecting rainwater, thus relieving pressure from drainage systems. Green infrastructure like rain gardens or bioswales may help capture and absorb rainwater into green infrastructure areas that reduce drain load while helping the drainage systems manage rain more effectively.
Flooding can occur throughout the Northeast and Midwest regions due to climate and topography issues. Heavy rainfall events during spring and summer seasons cause rivers and streams to overflow their banks, increasing flooding risks considerably.
Additionally, these regions feature flat terrain, which makes drainage of excess water more challenging; consequently, flooding may occur as accumulation occurs on the ground surface.
Infrastructure such as dams and levees must be maintained and upgraded to minimize flood risks in these regions to regulate water flow. Furthermore, floodplain management strategies like zoning regulations can prevent development in flood-prone areas.
Although known for its dry climate, the Desert Southwest can also experience flash flooding events due to heavy rainfall in localized areas. Flash floods happen when large volumes of water accumulating quickly within short amounts of time in one area can quickly flood a nearby location, causing localized flash flooding events that often require rescue services to contain.
Desert Southwest soil can often be hard and dry, making water hard to penetrate the ground and instead run off into dry streambeds known as arroyos - potentially becoming dangerous channels when flash floods arise.
To minimize flash flooding in the Desert Southwest, homeowners should avoid building in arroyos or low-lying areas and install flood barriers or elevate electrical equipment as part of a safety measure.
Coastlines can be especially susceptible to flooding due to their proximity to the ocean. Storm surges caused by strong winds and low-pressure systems can quickly raise water levels in low-lying areas and flood these spaces, potentially flooding low-lying regions with unexpected and devastating force.
Additionally, sea level rise due to climate change is making coastal regions increasingly susceptible to flooding, even minor storms causing significant damages and disruptions to property and infrastructure.
To reduce the risk of flooding in coastal areas, coastal protection measures such as seawalls, dikes, and beach nourishment must be implemented. Building codes and zoning regulations must also be updated for increased flood risk.
Floods pose a grave danger to property and life in many regions, from urban areas, Northeast/Midwest US regions, Desert Southwest US region, and coastal locations. Each has unique factors contributing to its susceptibility; measures can be taken, however, to lessen risks while mitigating damage caused by floods.
Investment in drainage systems, dams, and levees is vital to reduce flooding risks in urban and rural environments. Green infrastructure like rain gardens or bioswales may help absorb rainwater to ease the strain on drainage systems and alleviate some of its burdens.
Floods can strike anywhere and anytime; their risk increases with climate change. Reducing our risk is necessary for protecting lives and property and adapting to climate change; working together, we can mitigate flood damages while creating more resilient futures for our communities.
