A waterfall is a form of water flow in nature where a river or stream falls vertically from a high point.
Waterfalls are natural features that vary in form, with some reaching hundreds of meters in height and others only tens of centimetres.
Waterfalls are usually formed by the erosion of water flowing over rocks or cliffs, and some are formed because of geological formations.
Waterfalls are of great ornamental value in nature and attract a large number of tourists to see them.
Waterfalls can be divided into several forms, the most common being single-stage waterfalls, where a river or stream falls from a high point in one go. There are also stepped waterfalls, where the waterfalls then travel a horizontal distance to fall again. In addition, there are more levels of cascading waterfalls, as well as special forms of hanging waterfalls and so on.
The height of the waterfall, width, water volume and speed of water flow, and other factors will affect its ornamental value. The higher the height, the greater the volume of water, and the faster the speed of the waterfall, will usually give a more spectacular visual impact.
The natural environment around the waterfall will also affect its ornamental value, such as cliffs, rocks, trees, etc., and can add a lot of colour to the waterfall.
