Challenge Problems

Push your limits with challenges.

Question 1

You are conducting a hydrographic survey in a harbor where tidal fluctuations can be up to 3 feet. If your raw depth measurement is 15 feet, calculate the tide-corrected depth during high tide.

💡 Hint: Consider the highest point the tide can reach when adjusting.

Question 2

Different tide gauge types present varying accuracies. Choose a type of tide gauge for a coastal region known for heavy tidal waves, and justify your choice.

💡 Hint: Think about what type would function best in turbulent conditions.
