Your message should report on the which cracks in your dam grew and why. You must now estimate the loss of life if your dam failed. Fill the answer in on your worksheet. Then move to the Scenarios section to use the loss of life estimation, again filling in the questions on your worksheet. Now you must consider what you have learned about cracking and dams.
Dams provide many services but also cause many problems.
The five page worksheet is here and each page should be printed out and filled in as you go along. In this WebQuest you have learned about the services dams provide, the impacts dams have on the environment, simulating cracking in a dam, and estimating the loss of life if the dam fails. These are all things that civil engineers must take into account when they are deciding if a dam should be built or repaired or taken down. The engineers must work together, as you did, to solve their problems and make their decision about a dam.
