Define geometric similarity in your own words.
Think about what it means to replicate shape and size.

What defines geometric similarity?
Think about replication of the size and shape.
True or False: The discharge in a model should be greater than the prototype discharge.
Consider what happens as you scale down.
Design a model for a prototype bridge that is 300 meters long, 30 meters high, and 10 meters wide. If the model is to be built at a scale of 1:50, what will the model's dimensions be?
Remember to divide each dimension of the prototype by 50.
Evaluate how a model of a storm surge barrier that is scaled down by the ratio of 1:200 could influence an engineer’s decisions before constructing the full-scale barrier.
Consider what valuable information can be gathered through physical observation of the model.
