In landscape waterscape design, the most commonly used form of waterscape expression is “fountain”. It is a combination of dynamic and static waterscape art, and the main work component to complete the artistic modeling of the fountain is the small fountain nozzles. It takes water with a certain pressure through a shaped fountain nozzle to form a gorgeous spray and spray it on the surface of the water. A variety of different fountain nozzle combinations can create a variety of waterscapes and produce wonderful artistic effects.
