Johnstown Flood, 1889
In May 1889, a huge spring storm formed over Nebraska and moved east. Days later, it arrived in Johnstown, Pennsylvania.
Ten inches of rain fell in a little less than 24 hours, causing a local damn to break. Seeing that this was 1889 and the telephone was still a luxury for the rich, there really wasn’t much by way of a warning system.
More than 2,200 Pennsylvanians perished.
Galveston Flood, 1900 (Belle)

"In reality, there was no island, just the ocean with houses standing out of the waves which rolled between them." That’s what U.S. Weather Service meteorologist Isaac Cline wrote in his memoirs about fallout from the Category 4 hurricane that obliterated the island of Galveston, Texas, on September 8, 1900. Estimated death range between 6,000 and 12,000. That’s a tragedy, no doubt, but given the storm surge (16 feet) and that the highest point on the island was only nine feet, it’s a miracle more of the island’s 40,000 inhabitants didn’t perish. Property damage was estimated at $30 million.
Black Hills Flood, 1972 (Caanan)

Over a six-hour period on June 9, 1972, 15 inches of rain inundated Rapid Creek in the Black Hills of South Dakota. This surge in water lead to a breach in the Canyon Lake Dam, which sent water gushing into the town of Rapid City. The destruction was staggering: 238 deaths, 357 injuries, and 1,335 homes destroyed. And the property damage was over $160 million in 1972 dollars—or just north $866,000,000 in 2013 dollars. (Caanan)
The Great Flood Of 1993

For 81 days in 1993, Mississippi River stayed at flood stage, killing 50 people and causing $15 billion in flood-related damages. It was "the flood that came and stayed forever," said Robert Holmes, a flood expert with the U.S. Geological Survey. Thousands of people living in the floodplain were evacuated. Water from the flood covered over 17,000 square miles of normally dry land.
Hurricane Katrina, 2005 (Hermione)

One of the most debilitating natural disasters to ever hit the United States, Hurricane Katrina struck the Gulf Coast on August 29, 2005 and its effects are still felt, more than eight years later. More than 80 percent of New Orleans flooded, and the waters did not recede for weeks. The costliest natural disaster in U.S. history—New Orleans and the surrounding communities suffered $81 million in damages—also killed more than 1,800 people. (Belle)
By: Caanan Jarrah, Belle Vasquez Hermione Martinez, Clara Dunn,
Flooding occurs most commonly from heavy rainfall when natural watercourses do not have the capacity to convey excess water. However, floods are not always caused by heavy rainfall. They can result from other phenomena, particularly in coastal areas where inundation can be caused by a storm surge associated with a tropical cyclone, a tsunami or a high tide coinciding with higher than normal river levels. Dam failure, triggered for example by an earthquake, will result in flooding of the downstream area, even in dry weather conditions.
Timeline of the 5 biggest in US History
Dike- A high wide wall that prevents a body of water from flooding to the surrounding land.
Floodgate- A gate that controls a flow of water
Submerge- To go completely underwater
High-Water Marks- The level reached by sea water during high tide
Inundation- The rising of a body of water onto normally dry land
Abrupt- Sudden and unexpected
Deluge- A very heavy fall of rain
Outpouring- Sudden production of water in large amounts
Waterline- The highest point where water touches something
Flood head- A wall of water rushing ahead of the flood

The additional impact of flood

Although floods are NATURAL disasters, people have lot to do with it too. Our man made objects (levees) have gotten in the way of the course of bodies of water.

Also all of the pollution that we have caused made it so that the weather changes and causes floods.

Think of water running down a big wide ditch that’s, 50 feet across. Now make that ditch into a narrow pipe only 10 feet across. We turned Large ditches into small Levees.

Big Ideas
Assessment Questions
1. How have we as human beings contributed to the negative impact a flood has on Society?
2. What type of communities are at risk of a flood?

Communities in low areas are at a higher risk of flooding than communities in higher areas. Communities in low areas are subject to most damage also.

Various Types of Graphs
From 1940-2011 the percentage of flood related fatalities was 24%
Various Types of Graphs
From 1900 to 2013 floods have been the most costly natural disaster.
Various Types of Graphs
Since 2004, there have been 17,540 flood related fatalities.
During floods roads, automobiles, and buildings get destroyed.

The damage of a flood is very costly to both people and the government.

The cost of floods in the U.S alone in 2011 was $8,640,031,956.
Chemical substances can completely contaminate the bodies of water.

In 2011, a huge flood hit Japan and caused the leaking of many nuclear plants and caused detection of high radiation.
People and animals
Many people and animals died in flash floods

There us so much damage after a flood that water and electricity are completely shut off
3. What are leeves?
Detailed list of what to do in case of emergency

Avoid walking or driving through flood waters.
Just 6 inches of moving water can knock you down, and 2 feet of water can sweep your vehicle away.
If there is a chance of flash flooding, move immediately to higher ground. Flash floods are the #1 cause of weather-related deaths in the US.
If floodwaters rise around your car but the water is not moving, abandon the car and move to higher ground. Do not leave the car and enter moving water.
Avoid camping or parking along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.

4. Saint Felix, Holland November 1, 1530, About 400,000 estimated deaths
3. Yellow River China, October 1887, About 900,000- 6,000,000 estimated deaths

1. Yellow River China, August 1931, About 4,000,000 estimated deaths
How likely would a flood occur in Oceanside?
Flash Floods are very common in our area. Because of heavy rainfall, small ditches tend to overflow and spread to surrounding areas. Very recently flash floods have happened in our very school, when it was raining very hard. Such as El Nino
( In a flood, he STLLL needs to go out to eat!!!!!!)
(Even though her house is probably destroyed, she still finds a way to be happy. Way to go mom!)
Ma'am, you forgot your change
I lost my keys, can you help me find them?

We're just kidding, these situations are very serious.
(When you have a crush and you want to stare her/he
