What aspects should be considered when designing a square fountain?

Most ancient civilizations had urban water storage tanks to preserve drinking water. The Greeks and Romans used water pipelines to transport water to various parts of the city, while also utilizing gravity to make water gush out. So the origin of square fountains was actually to provide free drinking (and daily) water, and this function still exists in many fountains in Europe and America to this day. 
In the Middle Ages, public water supply systems were basically non-existent, and most public fountains in Europe were abandoned, only appearing in literary works or private gardens. The square fountain also symbolizes the source of life, purity, wisdom, and the Garden of Eden from this moment on. 
During the Renaissance, Europe began to rebuild fountains as public buildings, mainly as sculptures and decorations. The large number of beautiful fountains on the streets of Rome were mainly built between the 15th and 18th centuries. 
What aspects should be considered in the design of a square fountain? Square fountains have become quite common in recent years and have become a beautiful scenery. The design of square fountains is also an important issue in making square fountains. Therefore, two aspects need to be considered: integrity and participation. 
entirety: 
1. Spatial structure order: 
The layout of water bodies in water landscape design can play an important role in the overall spatial order of public spaces. Water is the main structural system of space. Linear water features have strong guiding properties and are often used in the design of urban squares to organize space and guide pedestrian activities; The rich forms and connotations reflected by water features easily make them the visual focus and thematic content of the square. 
2. Space atmosphere 
Water features have strong infectivity, and the main purpose of introducing water features in squares is to create an atmosphere. Different spaces have different atmospheres, which depend on the different forms of water landscape expression. 
3. Environmental Wind 
The environment in which water features are located is the background of water feature expression, and the style of water feature expression should maintain overall coordination and consistency with the style of surrounding buildings and square design. 
Participatory: 
The key to designing a square fountain lies in mobilizing people's participation. The participation here is not just about watching, but more about experiencing the water, such as the height of the water surface and the distance from the viewer, which greatly affects the viewer's psychological distance.
