Calculate the speed of the undertow

Reference no: EM13551435

1. Given the following Variables, calculate the speed of the undertow (assuming no rip) and the speed of the rip current (assuming no undertow) that would develop.

2. Using a scatterplot, explain how the speed of the undertow and rip vary with wave height and period and how the rip current also varies with the cross-sectional area of the channel and the spacing of channels.

3. On the following page is a 2002 satellite image of a beach on the Caribbean Coast of Costa Rica. How many rips are in this picture? You can find this place on Google Earth using the coordinates on the bottom right of the page.

4. Which of the rips would you predict to be the strongest? Why?

5. Graduate Student Question: How can you have both undertow and rip currents simultaneously?

6. Graduate Student Question: Why doesn't the set-down outside the surf zone create an opposite current?
