Answer:
Floods are the most common natural disaster in the United States.1 Their damage is so extensive that they are responsible for 90% of all damage related to U.S. natural disasters.2
According to the National Weather Service, floods kill 95 people a year on average.3 Flooding killed 93 Americans in 2019 alone.4 Let's look at what causes these dangerous weather events—and what can be done.
Explanation:
What Causes Floods?
Global warming is causing more floods. As temperatures rise, the air holds more moisture. Rainfall becomes less frequent, creating droughts. At some point, the skies release their moisture in a torrential downpour. That creates floods. Instead of soaking into the ground, the water runs on hard-packed earth that has dried out during the drought.5
Climate change may also cause floods by shifting the pattern of the jet stream. The Arctic is warming faster than the temperate zones, which can change the air pressure and turn the jet stream. When it plunges south, it can pick up tropical moisture from the Gulf of Mexico and dump it on the East Coast.6
Higher temperatures also mean less snow and more rain. One-sixth of the world's population relies on snowmelt for its water supply. They expect slowly melting snow to supply water at a steady pace. Instead, they will receive buckets they aren't prepared to store.7
Along the shoreline, rising sea levels are making floods worse. Consider these facts affecting Florida:
In Miami, the ocean floods the streets during high tide.8 To cope, the City of Miami Beach launched a five-year, $600 million public works program.9
Harvard researchers found that home prices in lower-lying areas are rising more slowly than those in the rest of Florida.10
A study using Zillow found that properties at risk of rising sea levels sell at a 7% discount to comparable properties.11 They include Key Biscayne, Sunny Islands, and Golden Beach as well as Miami Beach.12
By 2030, Miami Beach homes could pay $17 million in higher property taxes due to flooding, the Miami Herald reported. At the same time, nearby properties that are at higher elevations are experiencing rising prices.
Extreme weather will increase flooding. Over the next few decades, river floods will threaten tens of millions of residents. A 2018 study found that over half the United States will need to double existing flood protections.13
Major Flood Events in Recent Years
The past decade has seen record flooding across the United States. Here are just a few examples.
2019 Floods
Record snow and rain flooded several Midwest states in March 2019. Three people died and thousands had to evacuate. Damage estimates were $10.9 billion.14 At least 13 Missouri counties were declared major disaster areas.15 The Nebraska Department of Agriculture said flooding could cost the state $440 million in crop damage and $400 million in cattle losses.16
The National Oceanic and Atmospheric Administration warned that 25 states along the Mississippi faced flooding through May 2019. The heaviest flooding occurred along the Mississippi basin in North Dakota, Minnesota, Nebraska, Iowa, and Missouri.17 Ultimately, these states' levee systems could not withstand crest levels that reached as high as 25 feet.
In 2017, the American Society of Civil Engineers gave the U.S. levee system a D grade, estimating that it would cost $80 billion to bring the system up to standards.18
2018 Floods
In 2018, floods killed 80 people, slightly fewer than the 116 people in 2017.1920 In July 2018, the National Weather Service announced "dangerous, life-threatening floods" from Pennsylvania to North Carolina, affecting millions of people. Area storms delayed flights in New York and Philadelphia.
Record Mississippi River Floods
The 2011 Mississippi River flood was historic. The river experienced historical crests, while dams and levees were breached. Heavy snowmelts, historic rainfalls, and April's tornadoes triggered flooding from the Ohio River, as well.21 Fear of flooding oil refineries spiked gas prices. That fear subsided with the opening of the spillways, and gas prices dropped.
The Army Corps of Engineers estimated it cost $2 billion to repair the damage caused by the flood.22 The Mississippi River runs past farmlands and cities in six states. Damage from the flood made these communities more vulnerable to future floods. The Corps received $802 million from Congress to identify and repair the weakest areas.23
The 1993 Mississippi flood was the costliest U.S. flood of the 20th century. It caused $15 billion in damages.24 The National Oceanic and Atmospheric Administration reported that more than 20 million acres in nine states were flooded. Approximately 54,000 people were evacuated, while 50,000 homes were destroyed or damaged. The flood swamped 75 towns, some of which were never
