【摘要】：建立二維鹽度數(shù)值模型,計算區(qū)域包括大通至長江口及其鄰近海域,設(shè)計高分辨率網(wǎng)格,數(shù)值模擬和分析在不同大通流量等級下長江口鹽水入侵形勢,計算出中小潮期間長江口重要水庫取水口處鹽度均值為0.5‰時對應(yīng)的臨界大通流量。利用模型分析長江口鹽度場對上游大通流量的敏感性。本文對臨界大通流量的計算研究有助于提高預(yù)報長江口鹽水入侵模型精度,為長江口水庫避咸蓄淡提供參考;鹽水入侵對流量的敏感性研究可以為改善鹽水入侵情況提供技術(shù)指導(dǎo)。
[Abstract]:A two-dimensional salinity numerical model is established. The calculation area includes Datong to Changjiang Estuary and its adjacent sea areas. High resolution grids are designed. Numerical simulation and analysis of salt water intrusion situation in Yangtze Estuary under different Datong flow levels are carried out. The critical Datong discharge is calculated when the average salinity at the intake point of the Changjiang Estuary is 0.5 鈥，
