【摘要】：為弄清磨刀門水道河床演變及其沖淤成因,利用歷年實測地形資料,建立DEM模型,進行河床演變分析,結(jié)果表明:磨刀門水道主槽不斷沖刷,灘地有淤有沖。從上游來水來沙條件、河床邊界條件、人類活動等方面進行沖淤成因分析,確定主要影響因素,預(yù)測河床演變趨勢,為將來河道治理與開發(fā)提供科學(xué)依據(jù)。
[Abstract]:In order to understand the evolution of the river bed and the causes of scour and siltation in the Moriaomen waterway, the DEM model was established based on the topographic data measured over the years, and the analysis of the river bed evolution was carried out. The results showed that the main channel of the river was continuously scoured, and there was silt and scour on the beach. The causes of scouring and silting are analyzed from the aspects of upstream water and sediment conditions, river bed boundary conditions and human activities. The main influencing factors are determined, and the evolution trend of river bed is forecasted, which provides scientific basis for future river regulation and development.
