1. Introduction Like the arteries of the earth, rivers are a source of life and civilization, forming an important part of the natural resources and ecosystems that provide a necessary basis for human survival. In the 1970s, the concept of river health was first proposed in the United States [1]. A healthy river is defined as one that achieves a balance or compromise between socio-economic, ecological, and environmental values and whose social and natural functions are developed in harmony [2].
