The Panama Canal is one of
the largest and most difficult engineering projects of all time. It is often considered an eighth wonder of the world, and for this reason it was chosen to research for the CEE 514 Coastal Engineering final project.
The motivation for the project, the coastal environment of Panama, issues and approaches, a model of the Canal, results and discussion, as well as references are all presented in this website. University of Wisconsin Madison

Although the beams are usually seen within the Arctic Circle, they have been spotted in other parts of the world including the United Kingdom.
|
| Fun Fact 8 |
What causes the Northern Lights? The coloured beams are created by electronically charged particles from the sun which enter the Earth's atmosphere when solar winds are powerful.
|
| Fun Fact 9 |
The Earth has its own magnetic field which protects us against solar winds most of the time. However, sometimes electronic particles can pass through the atmosphere surrounding our Earth where the magnetic field is weaker.
|
| Fun Fact 10 |
There are many myths surrounding the dancing lights of the Aurora Borealis. Some believe the mystical phenomenon to be a 'Dance of the Spirits'. There are lots of legends and myths which have been around throughout history.
|
| Fun Fact 11 |
The color of the lights depend upon the atmosphere. Green light is given off high in the atmosphere where as the lower lights at lower altitudes can be other colours such as blue or purple.
|
| Fun Fact 12 |
The Northern Lights Oval is the area which provides the greatest possibility of seeing the Aurora Borealis. This area includes Alaska, parts of Canada, Norway, Greenland, Sweden, Finland and Iceland.
|
| Fun Fact 13 |
It has to be dark to see the Northern Lights at their greatest, between the hours of 6pm and 4am are usually the best.
|
| Fun Fact 14 |

Many of the best viewing areas are remote and due to extreme weather conditions they are inaccessible.
