The greatest impact of human activities on the geomorphology of rivers is to restrict the diversion of rivers, and the diversion of rivers in ancient times brought great disasters to the people. In addition, human beings take water for irrigation, drinking, etc. to reduce the amount of river water, the construction of reservoirs to change the river landform, the discharge of wastewater to change the river water quality, biological changes and so on. The impact is quite large.
The rivers are polluted, as you can see with your own eyes.
