Tides• Dynamic Theory of Tides

• Ideal Open Ocean Tide Theory

• Adds in Coriolis effect and actual depth and shape of ocean basins

• Tidal energy reflects of ocean basin boundary (continental margin)

• Travels as a shallow water wave

• Reflected energy rotates around a point node – acts like a seiche
