What is a 500-year flood? (video)

Facebook
The term 500-year flood doesn’t necessarily mean that it’s only going to happen one time every 500 years. Rather, it’s a reference to the probability of occurrence. youtu.be/eQFyaXDH42U #FloodScience

Survivor Story: Flood

I was driving a half-ton 4x4 which provides some comfort about not getting stuck in the mud. As I drove down the dirt road, I came across a low-water cement bridge. The bridge was completely covered in water, but not deep. I made a critical decision to turn around and drive the long way around to another highway. The next morning the water had receded and there was a huge hole — the water had washed away the dirt where the road met the cement. I would have surely lost the vehicle and maybe our lives…just saying “Turn Around and Don’t Drown” saved life and property. -- Julie, Nashville, TN, 2018 

 

Science of River Flooding

Water is essential for life on Earth. But in large enough quantities, the very substance we drink and use to grow crops can destroy homes, businesses, and cause fatalities.

SCIENCE OF RIVER FLOODING - Water is essential for life on Earth. But in large enough quantities, the very substance we drink and use to grow crops can destroy homes, businesses and cause fatalities. River flooding occurs when river levels rise & overflow their banks or the edges of their main channel and inundate normally dry areas. River flooding can be caused by heavy rainfall, dam failures, rapid snowmelt and ice jams. Six Steps to Create a River Model Hydrologic Cycle: Hydrologists try to understand and simulate the natural hydrologic cycle, which is the intricate combination of many processes such as evaporation, transpiration, precipitation, infiltration, interflow, groundwater storage, and runoff. Precipitation: Precipitation is the primary input to basin hydrologic processes and serves as the primary driver of hydrologic models. Accurate representation of precipitation input is an important intial step. Small river channel systems are very sensitive to rainfall. Runoff: The next step is to compute the amount of precipitation that appears in surface water within a relatively short time from the onset of a storm event. This is runoff. Runoff consists of 3 components: overland flow, rain falling directly on surface water bodies, and interflow. Unit Hydrograph: After computing basin runoff, the next step is to calculate a forecast hydrograph in units of discharge. A hydrograph is a plot of the change of stage or discharge with respect to time. Discharge is the volume of water flowing past a location per unit time and is usually expressed in cubic feet per second (cfs). Streamflow Data: Scientists use streamflow measurements to capture the vital relationship between discharge (volume flow rate) and stage (height) for a given location. This can only be done by taking streamflow measurements at different river levels and noting the corresponding stages. This relation is called a rating curve. Routing: Hydrologists analyze and interpret how the water moves once it’s in the river and how a flood wave is modified due to the effects of storage and friction as it moves downstream. So, what happens upstream affects the entire downstream community. 

 

Stay Out of Floodwaters

Facebook
Play in the pool, not in floodwaters! Floodwaters can contain harmful chemicals and objects that could harm you or make you sick. #FloodSafety http://www.noaa.gov/resource-collections/watersheds-flooding-pollution

Play in the Pool, Not in Floodwaters! Floodwaters can contain chemicals, sewage, and disease. Unseen underwater debris can be sharp and cause injury. Water depth can change unexpectedly (storm drains, washed-out roads)

 

Flash Floods and Rain

Facebook
Heavy rainfall always brings a danger of flash flooding, but sometimes even light/moderate rainfall can trigger dangerous floods. Dry stream beds can become raging torrents in minutes with no rain in sight! Stay safe from floodwaters and learn more at http://www.weather.gov/media/wrn/floods_booklet.pdf#page=3

How Much Rain Can Cause Flash Flooding in Your Area? Even a little rain can cause a lot of flash flooding. Dry stream beds can become raging torrents in minutes with no rain in sight!

 

Flood Warning vs. Watch

Facebook
A flood WARNING means TAKE ACTION. A flood WATCH means BE PREPARED. When a Warning occurs, it means flooding is imminent or already occurring. When a Flood Watch is in effect, it means flooding is possible in your area. weather.gov/safety/flood-watch-warning #FallSafety #FloodSafety

Twitter
Warning means TAKE ACTION. Watch means BE PREPARED. weather.gov/safety/flood-watch-warning #FloodSafety #FallSafety

Flood Warning: A Flood Warning is issued when flooding is happening or will happen soon. Move to higher ground. Never drive through flooded roads. Flood Watch: A Flood Watch is issued when flooding is possible. Stay tuned to radio/TV, follow weather.gov and be ready to seek higher ground. Learn more at weather.gov/flood 

 

3 Steps for Flash Floods

Facebook
During a flood, water levels and the rate at which the water is flowing can quickly change. Get to higher ground. Do not drive or walk into water. It only takes 6 inches of water to knock you off your feet. Stay informed by monitoring local radio and television for updates. weather.gov/flood #FloodSafety #FallSafety

3 Steps for Flash Floods: 1. Get to higher ground (get out of the areas subject to flooding). 2. Do not drive into water (do NOT drive or walk into flooded areas. It only takes 6 inches of water to knock you off your feet). 3. Stay informed: Monitor local radar, television, weather radio, internet or social media for updates. During a flood, water levels and the rate at which the water is flowing can quickly change. Remain aware and monitor local radio and television. WHEN FLOODED TURN AROUND DON'T DROWN

 

Driving Around Barricades

Facebook
NEVER drive around barricades into floodwaters! More than 50% of all flood fatalities are vehicle-related. It only takes 12 inches of fast-moving water to carry off a small car and 18 inches of water to sweep a larger vehicle away. Turn Around Don’t Drown! weather.gov/safety/flood-turn-around-dont-drown #FloodSafety #FallSafety

Twitter
Half of all flood fatalities are vehicle-related. Turn Around Don’t Drown! weather.gov/safety/flood-turn-around-dont-drown #FloodSafety #FallSafety

Never Drive Around Barricades. Most flood fatalities occur in vehicles. 12 inches of fast-moving water can sweep a car off the road.

 

Infographic - Power of Water

Facebook
Don’t underestimate the power of water. It only takes 6 inches of fast-moving water to knock over and carry away an adult, 12 inches to carry away a car, and 18-24 inches to carry away most large SUVs, vans and trucks.

Hiking or Camping

Facebook 
Are you planning to camp or hike near a stream or river? Remember that it doesn’t have to rain directly over you for there to be flooding. If you notice even a slight rise in water level, seek higher ground immediately! weather.gov/safety/flood-during #FloodSafety #FallSafety

Flooding - Prepare

Flooding can occur during any time of the year. As a result, it’s always best to be prepared! To learn more about flooding and how you can prepare before it happens, visit weather.gov/flood. #FloodSafety #FallSafety

Prepare for flooding before it happens. Are you located in a floodplain? What is the fastest way to higher ground? What roads nearby are most likely to flood?

 

Debris Flows

Facebook
Debris flows often happen in areas where excessive rain causes soil to become so saturated it turns into very runny mud. The mud then races downhill, picking up debris such as fallen branches, tree trunks and rocks as it goes. Debris flows can bury homes under piles of mud and debris. Know the risks of the area where you live, so you can prepare your family and home before heavy rains threaten your area. weather.gov/safety/flood-hazards #FloodSafety #FallSafety photo:FEMA

Heavy rain can cause debris flows. Debris flows occur when heavy rain causes the soil to give way and slide downhill. Homes in the path can be completely destroyed.

 

Burn Scars

Facebook
If you live, work or are spending recreational time outside near an area recently affected by a wildfire, keep in mind that it will not take much rainfall to cause flooding. Land that was recently burned by a wildfire is called a “burn scar”, and when rain falls over a burn scar, the ground is unable to absorb much of the water, which often results in flash flooding.

Burn scars are a flood risk. Rapid rainfall runoff over burned areas can cause flash flooding. Stay weather-ready if you are in or near an area affected by a wildfire.
