For a long time, waterscape has been as an architectural language for urban design in some cities such as Venice, Amsterdam, Suzhou etc. In the same perspective, during urban formation from 1802 to 1945, water element was closely united with Hue City which was a relevant example of urban planning for sustainable development. Furthermore, the FengShui methodology also sets up water as an indispensable element in layout’s principle. In this context, waterscape of Hue City was built as an unusual combination of human and nature, the ideology of Eastern philosophy and traditional architecture of Vietnam. The  model of waterway was harmoniously unified with  monuments and landscape to create the identity of the local ecological system.

In the last decades, waterscape of Hue City has been experiencing main changes by the impacts of urbanization such as the changing livelihood of local people, environmental pollution, disconnected water, flood, causing variation of the characters of the traditional waterscape, harming the water system. Most of the precedent ideas of waterway tend to be broken down. Studying and identification of characters and values of water network’s structure are as the cultural heritage, tourism potentiality to preserve and promote a sustainable model which orients towards the local technology of environmental self-regulating.
