introduction：
dr. zhang is an engineer at nanjing hydraulic research institute. he received his bachelor's degree from hohai university in 2014 and his ph.d. in hydraulic engineering from tsinghua university in 2020 under the supervision of professor lin binliang. he is now responsible for 3 provincial and ministerial scientific research projects, including the national key research and development program and the jiangsu provincial water resources science and technology project, and has participated in more than 10 engineering projects for river controlling and waterway improvement. the research results have been published in journals such as water resources research. at present, the main research interests are the sediment dynamics in large rivers under human activities, the river-tide interactions, and the early warning of the riverbank collapse. this report aims to research the middle and lower yangtze river, reveal the temporal and spatial variation characteristics of the suspended sediment concentration and the response mechanism to the operation of the reservoir, explore the trend of the sediment exchange relationship between rivers and lakes, and predict the change of the sediment into the sea. the report will also briefly introduce examples of engineering problems in the lower yangtze river due to sediment reduction. on a global scale, the discharge regulation and sediment storage effects of large reservoirs have changed the river discharge and sediment transportation processes, which has become one of the key issues in the study of the reservoir-river-estuary system, and this study also provides new enlightenment for the management of these large river systems.
