Abstract: Reservoir building to meet human's growing need for water resources utilization is still an important mission in the water conservancy construction for the present world, especially for the developing countries. However, damming changes the condition of stream flow boundary as well as water and sediment transport, which trigger the corresponding adjustment of channel morphology. Large-scale dams have been built since the 1930s, asSociated with more and more researches focusing on the their impacts of dams building on downstream discharge regime, sediment decline and geomorphologic change. This paper devotes to emphasize rearrangement and summary on the global research progress of the above issues. A brief literature review on the historical and present situation for the reservoir-induced downstream changes of water, sediment and channel morphology is reported in this paper, aiming to conclude and sum up abundant research results in this field.

Key words: water and sediment changes, channel adjustment, downstream channel of dams, literature review
