Tidal Bore of the Qiantang River
This is a typical dramatic tidal scenery. Hangzhou Bay outside the Qiantang River has a wide and deep outer portion but a narrow and shallow inner part. It is a typical horn-shaped bay with an inlet approximately 100 km wide but a narrow channel approximately 20 km wide in Ganpu to the west. The river is only 3 km wide when it reaches Yanguan Town in Haining. When the tide comes in, the deep bay accommodates a large amount of seawater, but due to the rapid narrowing of the river channel, the tidal water moving upstream cannot rise in time and is pushed by the following waves. The waves rise progressively, eventually creating a scenery of rolling and roaring tidal flows. This scenery has been described as the most incredible tidal scenery, and the Qiantang River is considered the best place to watch this tidal bore landscape.
