An inlet or bay with a narrow opening and a large tidal range is ideal for generating tidal power. A tidal range of at least 5 meters is typically needed to make tidal power extraction feasible.
The shape of the coastline affect tides because of resonance. Resonance changes normal tide occilations. (see in the section of resonance, Hydrographic Volume II, Tide and Tidal Stream)
The tidal range may be small in some areas due to the geography and shape of the coastline, which can limit the flow of water. Additionally, factors such as the distance from the open ocean, the depth of the water, and local weather conditions can also impact the tidal range.
Tidal Energy
Tidal patterns are greatly influenced by the size, shape, depth, and location of the ocean basin in which the tides occur.
Tidal range is determined by the difference in water levels between high tide and low tide at a specific location. It is influenced by factors such as the gravitational pull of the moon and sun, the shape of the coastline, and the depth of the ocean. Tidal range can vary significantly from one location to another depending on these factors.
A spring tide has the greatest tidal range. A neap tide has a smaller tidal range.
The large tidal range in Jersey is mainly due to its geographical location in the English Channel, which experiences strong tidal currents. The funnel shape of the channel amplifies the tidal effects, resulting in a significant difference between high and low tides. Additionally, the island's relatively shallow waters further enhance the tidal range.
The Bay of Fundy in Canada is known for having one of the largest tidal ranges in the world, with tides that can reach up to 50 feet high. This dramatic tidal range is caused by the unique shape and depth of the bay, which amplifies the gravitational forces that create tides.
The tidal range is calculated by subtracting the height of the low tide from the height of the high tide. Factors that influence the tidal range include the gravitational pull of the moon and sun, the shape of the coastline, and the depth of the water.
The Bristol Channel has the 3rd biggest tidal range in the world of 15m.
Spring tides have a greater tidal range than neap tides.
