A port's predicted high water is 4.8 feet above MLLW. The predicted low water is 0.6 feet above MLLW. What is the tidal range for this cycle?
- A5.4 feet
- B4.8 feet
- C0.6 feet
- D4.2 feet✓ Correct
Explanation
Tidal range = high water height − low water height = 4.8 − 0.6 = 4.2 feet. The range is simply the vertical difference between the predicted high and low.
