Spring flooding in the Midwest has caused incredible damage to cities, towns, and agriculture, with the National Oceanic and Atmospheric Administration (NOAA) estimating $37.3 billion in damages. The catastrophic floods in the Midwest and Plains states, reminds us of the Great Flood of 1927 and 1993. But we’ve learned that it’s the conditions and preparation that precede the flooding that determine how much damage will go unstopped.
Potential causes of massive flooding:
- Snowpack and frost
- Moisture level in soil
- Streamflow and precipitation
These factors are all potential contributors to flooding. Precipitation in seven of nine Plains and Midwest states during fall of 2018 outweighed precipitation during fall of 1992. Similarly, eight of nine Plains and Midwest states had a wetter winter during 2018 and 2019 than in 1992 and 1993.
As the soil becomes saturated, it has trouble absorbing heavy rainfall, causing runoff into creeks and rivers. As the rivers fill up, the potential catastrophic floods increase.
In 1993, a cluster of large thunderstorms, known to meteorologists as mesoscale convective systems, dropped an incredible amount of rain on the Midwest and Plain states. Conditions for rainfall like this most often depend on air temperature.
Surviving a Flood
Three lives have been lost due to the flooding in the Midwest this year, according to NOAA’s weather and climate disaster table of events. The Department of Homeland Security has tips for facing floods natural disasters.
- Always evacuate if you are told to
- Don’t drive around barricades
- Stay off bridges
- Avoid contact with flood water
- Move to higher ground
Proven Solutions When Stormwaters Rise
According to NOAA , while states in the upper Mississippi and Missouri River basins (Nebraska, Minnesota and Iowa), are at risk of flooding, states in the U.S. east of the Mississippi River and portions of California and Nevada are also at risk of minor floods.
Landslides, erosion, and overflow of water systems are all potential effects of large-scale flooding. Sediment left behind as a result of flood waters, reduces water quality affecting the water supply.
Flood waters can also contain debris and nutrients, which can affect the water quality, encouraging the growth of algae.
Controlling sediment dispersion with a turbidity curtain helps to control erosion, blocking sediment and protecting wildlife and surrounding vegetation. Curtains like this are used to keep bodies of water silt free and keeping the quality of water high.
