What does flood current refer to?

• A. Movement away from shore
• B. Movement towards shore or upstream
• C. No horizontal movement
• D. Constant speed upstream

Answer: (B)

Flood current refers to the movement of water tide or current that flows towards shore or upstream. This phenomenon occurs during high tide when the water level rises, causing a flow of the tidal waters to move inland. This is particularly significant in coastal and estuarine environments where the interaction between the ocean and rivers can create complex current patterns. Understanding flood currents is essential for navigation, allowing vessels to anticipate how the changing water levels will affect their movement and positioning. Being aware of this can also assist in anchoring, maneuvering, and avoiding hazards. Recognizing the dynamics of flood currents can significantly improve safety and operational effectiveness for the Officer of the Deck.
