The　Lake　Tian　E　Zhou　(TEZ,　an　oxbow　lake)　was　formed　during　the　rerouting　of　the　Changjiang　River　in　1972,　with　strong　influences　from　the　main　river　channel　and　flood　events.　Herein,　a　sediment　core　was　collected　from　the　Lake　TEZ　for　the　measurements　of　carbon　isotopes　and　biomarkers,　including　stable　carbon　isotopes　(delta　C-13),　radiocarbon　composition　(Delta　C-14),　and　lignin　phenols,　as　well　as　lead-210　to　reconstruct　recent　heavy　flood　events　over　the　past　70　years.　At　the　24-26　cm　interval,　the　sediment　contained　the　highest　OC%,　TN%,　and　lignin　phenols　content,　as　well　as　significantly　depleted　C-13　but　enriched　C-14,　corresponding　to　the　extreme　flood　event　in　1998.　In　addition,　statistics　from　t-test　showed　that　lignin　phenols　normalized　to　OC　(?8),　the　concentration　of　3,　5-dihydroxy　benzoic　acid　(3,　5-BD),　and　the　ratio　of　p-hydroxy　benzophenone　to　total　hydroxyl　phenols　(PHB/HP)　were　all　significantly　different　between　the　layers　containing　flood　deposits　and　the　layers　deposited　under　normal　non-flood　conditions　(p＜0.05).　These　results　indicate　that　the　later　three　parameters　are　highly　related　to　flood　events　and　can　be　used　as　compelling　proxies,　along　with　sediment　chronology,　for　hydrological　changes　and　storm/flood　events　in　the　river　basin　and　coastal　marine　environments.
