New Orleans asks: Will the rebuilt levees hold?

Students asked about this issue last week in class.

NEW ORLEANS (AP) — Just three years after Hurricane Katrina, New Orleans confronts a new threat from Gustav and a stark question: Will the partially rebuilt levees hold?

levee and drain pipes
Despite $2 billion in improvements, including 220 miles of repaired, raised and replaced floodwalls, 17 new pump stations and more flood-resistant pump stations, nobody can say for sure the city won't be swamped again. And if it is, could it ever recover?

"It's scary, man," said Robert Russell, a 63-year-old plumber whose house in Gentilly Woods is close to floodwalls on the Industrial Canal that are so suspect the Army Corps of Engineers is buffering them with large baskets filled with sand.

"They say it's not up to code," he said. "We'll have to wait and see."

Levee experts and the Army Corps insist New Orleans is safer than before Katrina flooded more than 80 percent of the city on Aug. 29, 2005.

Yet the system still has severe shortcomings: Flood barriers meant only to withstand medium-strength storms, hidden layers of weak soil and navigation channels that inadvertently funnel storm surge into the city, to name a few.

"The positive thing about having any storm hit you, it will reveal any kind of frailty in the system," said J. David Rogers, an engineer at Missouri University of Science and Technology, who's tracked the construction closely. "And we shouldn't be surprised if there is frailty."

Experts estimate the system is only a third of the way to where the corps wants it by 2011 — strong enough to protect against what scientists call a 100-year-storm. That type of hurricane has a 1 percent chance of occurring each year.

By comparison, the corps says Katrina was a 396-year storm, a rare catastrophic hurricane. The agency has not classified Gustav, which was crossing Jamaica Thursday.

"We're not close to 100-year-level protection yet," said Robert Turner, the regional director of the Southeast Louisiana Flood Protection Authority-East. "It's not worth putting your life at risk if you have the means to get out."

Students should be confident that fairness exists across the classroom during tests. To that end I work hard to make sure these guidelines are evenly administered:

1. No communication between students; None whatever. Students may raise their hand and shortly I will arrive at their desk to answer the question. Please whisper your question.
2. You may Not trade or pass notes during the test period.
3. Keep your eyes on your workspace only.
4. You may use all sources of info: textbook, atlas, notes, print outs, reference books in the classroom, even a laptop.
5. Violation of test guidelines? I must call your parents and you must type an essay of correction and contrition.

- Cut out and color representations of 2 ships and 2 planes appropriate in size to your Great Circle maps.
- Place them upon your map, you ask? Yes! With glue? Perhaps, yes!
A disembodied hand and wrist? One that moves to and fro? If we have the time!
- Knowing the type of route on which you must place the ship and plane

Maps by Gerardus Mercator, mid 1500's

The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator, in 1569, says Wikipedia.

It became the standard map projection for nautical purposes because of its ability to represent lines of constant true bearing or true course, known as rhumb lines, as straight line segments.

While the direction and shapes are accurate on a Mercator projection, it distorts size, in an increasing degree away from the equator.

The nature of the Great Circle route

Originally uploaded by trudeau
Great circle routes are used by ships and aircraft where currents and winds are not a significant factor. For aircraft traveling westerly between continents in the northern hemisphere these paths will extend northward near or into the Arctic region, while easterly flights will often fly a more southerly track to take advantage of the jet stream.

A great circle is a circle on the surface of a sphere that has the same circumference as the sphere, dividing the sphere into two equal hemispheres, says Wikipedia.

A great circle is the largest circle that can be drawn on a given sphere. The diameter of a great circle is same as the diameter of the sphere.

When long distance aviation or nautical routes are drawn on a flat map (for instance, the Mercator projection), they often look curved. This is because they lie on great circles. A route that would look like a straight line on the map would actually be longer.

On the Earth, the meridians are on great circles, and the equator is a great circle. Other lines of latitude are not great circles, because they are smaller than the equator; their centers are not at the center of the Earth -- they are small circles instead.

The Mississippi Valley project

To be completed mostly in class, this review of the tributaries of the Miss. should have the following items:

1. 10 states - the ones that directly border the Miss.
2. The Miss. river.
3. The major tributaries -
Ohio R.
Tennessee R.
Missouri R.
Arkansas R.
Red R.
4. Add a rim of color to the states. Save a contrasting color for the rivers.
5. Titles (see guidelines).

The Mississippi River[2] is the second longest river in the United States, with a length of 2,340 miles (3,770 km)[3] from its source in Lake Itasca in Minnesota to its mouth in the Gulf of Mexico, says Wikipedia. The longest river, a Mississippi tributary, is the Missouri River measuring 2,540 miles (4,090 km)[4].

The Mississippi River is part of the Jefferson-Missouri-Mississippi river system, which is the largest river system in North America and among the largest in the world: by length (3,900 miles (6,300 km)), it is the fourth longest, and by its average discharge of 572,000 cu ft/s (16,200 m³/s), it is the tenth largest river.

The name Mississippi is derived from the Ojibwe word misi-ziibi ("Great River") or gichi-ziibi ("Big River") at its headwaters.

Wikipedia reminds us that "The Atchafalaya River in Louisiana is a major distributary of the Mississippi." What does that mean?

Ni hau! That's Mandarin Chinese for "hello."

What city lies at 39N, 116E?
a) Seoul, S. Korea
b) Shanghai, China
c) Beijing, China
d) Denver, Co

This week: grids, coordinates and map projections.

While this is a week on the basics of geography, we will also look ahead to our unit on the US.

- The importance of the Mississippi valley network, a non-digital information and social connection system.

How is Facebook like a modern version of the Mississippi valley?

The art of comparison, a higher-thinking theme of this geography class

Typical comparison work in this class will comprise the following elements. Typically, this will be the format for independent work.

- Base your essay on no less than 3 factual items for each topic.
- Open with a colorful, descriptive sentence.
- Switch back and forth between topics, which is called integration of topics. Do not give the info in separate blocks and add a final integration.
- Cite your sources (, teacher Robert Trudeau, etc) by the phrase “according to.” Place it at the end of the first sentence of each paragraph.
- Top it with a a) smacky title and b) explanatory subtitle
- Proofread your paper for * legibility * speeling * grammar
- Name, date & hour in upper right corner!
- Proofread one more time.

Ex.: Compare the 2008 and 2004 Olympic Games in regards locations: Athens, Greece and Beijing, China.

Greenwich, England, lies upon the Prime Meridian

The Prime Meridian is the meridian (line of longitude) at which longitude is defined to be 0°, says Wikipedia.

The Prime Meridian and the opposite 180th meridian (at 180° longitude), which the International Date Line generally follows, form a great circle that divides the Earth into the Eastern and Western Hemispheres.

Unlike the parallels of latitude, which are defined by the rotational axis of the Earth (the poles being 90° and the Equator 0°), the Prime Meridian is arbitrary. By international convention, the modern Prime Meridian is one passing through Greenwich, London, United Kingdom, known as the International Meridian or Greenwich Meridian.

America's largest crop: corn

Dead Corn
Originally uploaded by joblow
America’s largest crop is corn, says Wikipedia.

Corn is a readily available, reliable, storable and versatile commodity. In the average American supermarket, corn derived ingredients can be found in one-fourth of everything on the shelves.[2]

This includes not only food items, but also cosmetics, toiletries, cleaning products and household goods. Aside from that, corn is also used for the feeding of factory farm animals, for the production of alcohol, and can be used as a fuel source for both heat production and vehicles. On top of being a versatile commodity, corn has been genetically modified in a way that facilitates industrial-agricultural harvesting and large yields.

Between the years 1920 and 1980, US corn yields increased 333 percent and continue to improve.[3] The strains of corn used for industrial farming are engineered to grow in a uniform, perfectly upright fashion that facilitates mechanical harvesting. Corn is also modified to thrive in crowded conditions; one acre of land can accommodate around 30,000 plants and produce roughly 180 bushels of corn, with each bushel weighing in at 56 pounds.[4] Genetic modifications have made it possible for certain strains of corn to be naturally insect resistant.

Cheap and readily available chemical pesticides and synthetic fertilizers have contributed greatly to high crop yields; corn has also been engineered to tolerate chemicals and to efficiently utilize petrochemical fertilizers.[5] Increases in the productivity of corn have helped to keep food prices low. America’s number one crop has an undeniably important place in both the economy and in peoples' diets.

Note-taking skills in social studies class

Recommended practice . . .

- Leaving generous space between items.
- Learning to shorten sentences and to use abbreviations.
- Using sketches to punctuate and illustrate items.
- Using color for accent.
- Underlining key words.
- Asking questions of the teacher when in doubt.

Rain hampers the local corn harvest; what are the implications?

This morning I talked with teacher Margaret Nance about her farm in Dixie. She said the August rains - ordinarily expected in September - were stopping the harvest. The harvester machines cannot work the fields when there is too much mud. She added that the farmers are under contract to deliver their crops at a certain time.

So I asked geography students to write a brief answer to the query "Rain hampers the local corn harvest; what are the implications?"

First, students wanted to know the definition of "implication." It is something that is not stated directly but something that is suggested.

The implications? The price of corn may rise. Many students smartly pointed out that supply and demand might cause the price increase.
Other students said that supplies of Ethanol, a fuel made from corn, might be affected. A few students pointed out that prices of beef and soft drinks and even ice cream might rise because these products are based partly on corn.

All things considered, it gave students a chance to use a higher level of thinking and their background in current events.

Implication? Studious, intelligent, careful

The truth of the matter is that I don't know whether Joseph is studious and careful. He was placed in my class only today. But something about this photo of him implies those qualities.

To imply is to suggest. One must interpret to draw an implication.

Today's question was -
"Corn harvest in Caddo upset by rain. What are the implications?"
Thus we are looking for the things that will happen in the overall marketplace as a result of this slowdown in harvesting this important grain.

B&N, Amazon, Ebay: no problem getting a Rand McNally Quick Reference World Atlas

Recycling comes to Shreveport via the Red River

Paper recycling tricycle
Originally uploaded by supercamel
Pratt Industries has broken ground on construction of its third, 100% recycled containerboard mill, says the Pratt Industries web site. The facility, located in Shreveport, La., will open in late 2008, and will eventually produce more than 360,000 tons of recycled paper a year to supply the company's growing internal demand for more paper.

It will also create more than 115 full-time jobs on site, while state officials estimate almost 1700 new jobs, direct and indirect, will be created during the construction phase.

"This mill symbolizes our continued commitment to growth for our company, for our customers and for the paper/packaging industry," said Chairman and CEO Anthony Pratt. "This means quality manufacturing jobs for Americans."

The Shreveport machine, which will be arrive in June, is being designed by the Italian group, Overmechanica. It will be committed to using 100% post-consumer fibers as do Pratt's other two mills in Conyers, Ga., and New York City.

And Louisiana officials are thrilled the company is coming to the state. Outgoing governor Kathleen Blanco said: "Pratt's strong stance on environmental protection makes them a great fit with Louisiana. This 'green' investment will significantly enhance the conservation of our natural resources."

The new mill will make lightweight and medium line on a 220-inch trim, fourdrinier paper machine.

Pratt also plans to roll out a recycling program throughout the region to help supply the mill's fiber needs.

What was the state of the Red River in 1812?

Red River, Shreveport LA
Originally uploaded by roy.luck
The American rivers were still difficult to navigate, however, because of the presence of dead wood called snags, sawyers [1], or log jams, says Wikipedia.

Henry Miller Shreve was appointed Superintendent of Western River Improvements in 1826 and charged with finding a solution to this problem. He had been working on a design for a "snagboat" since 1821, and he finally had it built in 1827. This craft, the Heliopolis, had a steam-powered windlass used to pull large concentrations of dead wood from the water. As a result of the success of his design, Shreve was ordered in 1832 by Secretary of War Lewis Cass to clear the Great Raft, 150 miles of dead wood on the Red River.

Shreve successfully removed the Raft (despite inadequate funding) by 1839. The area of the Red River where the Raft was most concentrated is today his namesake city of Shreveport. Shreve helped to establish Shreveport via the Shreve Town Company. In 1841, Shreve was relieved of his superintendent's duties by the nominally Whig U.S. President John Tyler. He hence retired to his farm near St. Louis.

Pratt Industries Paper Recycling Plant enables Shreveport to have recycling collection

In 2007 one of the world's big paper recycling companies, Pratt Industries, located a plant at the Port of Spt-Bossier - on the Red River.

It is a contract w Pratt Industries that allows the city of Shreveport to have a curbside recycling program.

Pratt recycles the paper goods. It sells the glass, plastic and metal to other companies.

Pratt uses the Red River for cheap transport.

Maybe one day you will create a recycling facility. Either that or we'll end up like the people in the movie Wall-E.

Demographics: World Population

World Population
Originally uploaded by hugoahlenius
The demographics of first year students at CMHS, the Class of 2012, encompasses some 15 middle schools. While a large number of our students come from CMM, in many classes the majority of students are from many different middle schools.

Therefore, there's a great need for making new friends.

Demographics is the study of populations. How many students at CMHS are age 14? How many age 16?

The demographics of the city of Shreveport are currently painful. Shreveport's population is shrinking, according to Census reports as published in the Times. We have slipped below the 200,000 mark. Therefore, the student population of Caddo schools is shrinking.

When we look at demographics, we see statistics. But the key to using demographics is in the interpretation of those facts. The value lies in finding trends.
