The correct answer is option 2: Tidal Bore. When a tide enters a narrow and shallow estuary of a river, the front of the tidal wave can appear to be vertical. This occurs because the water of the river is piled up against the tidal wave and there is friction with the river bed. This vertical wall of water is known as a tidal bore.

Let`s briefly explain the other options to better understand why they are not the appropriate names for this phenomenon:

1. Tidal Current: Tidal currents refer to the horizontal flow of water that occurs with the rise and fall of the tides. It does not describe the vertical wall of water formed in an estuary.

3. Tidal Bulge: Tidal bulge refers to the region of elevated water levels that occurs due to the gravitational pull of the Moon and the Sun. It is not specifically related to the formation of a vertical wall of water in an estuary.

4. Tidal Loop: This term is not commonly used in the context of estuaries or tidal waves. It does not accurately describe the vertical wall of water formed in this situation.

In conclusion, the appropriate name for the vertical wall of water formed when a tide enters a narrow and shallow estuary is a tidal bore
