Tide Tourism Landscape

A tidal landscape can have tourism value. The Earth is subject to solar and lunar gravitational forces during its rotation and revolution. The tides change daily; there is a morning tide and an evening tide, which are collectively called ocean tides. In ancient China, watching the tidal changes along the coast was regarded as a tourism resource. The tide-viewing in Qiantangjiang, Zhejiang, is most famous. Due to its trumpet-shaped estuary, seawater flows from the 100 km long inlet into the 3 km wide channel near Ninghai from the 100-kilometre-long inlet. Constrained by the narrow channel, the waves push against each other, forming a huge wall of water that makes a thundering noise as the water rushes like a thousand running horses. The maximum tidal range can reach 8–9 m, and during the large tide season, thousands of tourists come to watch the tides.
