報告內(nèi)容簡介
張帆一，南京水利科學(xué)研究院工程師。于2014年在河海大學(xué)獲學(xué)士學(xué)位，2020年在清華大學(xué)獲水利工程博士學(xué)位，導(dǎo)師為林斌良教授。負(fù)責(zé)國家重點研發(fā)計劃專題、江蘇省水利科技項目等省部級科研項目3項，參與長江河道治理、航道整治、過江通道建設(shè)等重大工程科研項目10余項，研究成果發(fā)表在Water Resources Research等期刊上。目前主要研究方向為人類活動下大型河流泥沙動力演變，感潮河段徑潮相互作用，潮汐河段崩岸預(yù)警等。本次報告旨在以大型水庫影響下的長江中下游為研究對象，揭示干流懸沙濃度的時空變化特征及其對水庫運行的響應(yīng)機制，探討河湖泥沙交換關(guān)系的發(fā)展趨勢，預(yù)測感潮河段入海懸沙濃度的變化。報告還將簡要介紹減沙背景下長江下游河道面臨的工程問題實例。在全球范圍內(nèi)，大型水庫的調(diào)蓄作用和攔沙效應(yīng)改變了河流徑流過程與泥沙輸運過程，已成為水庫-河流-河口系統(tǒng)研究的關(guān)鍵問題之一，本研究也為其他大型河流的管理提供新的啟示。
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 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 on 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 reservoir-river-estuary system, and this study also provides new enlightenment for the management of these large river systems.
