【摘要】:建立二維鹽度數(shù)值模型,計(jì)算區(qū)域包括大通至長(zhǎng)江口及其鄰近海域,設(shè)計(jì)高分辨率網(wǎng)格,數(shù)值模擬和分析在不同大通流量等級(jí)下長(zhǎng)江口鹽水入侵形勢(shì),計(jì)算出中小潮期間長(zhǎng)江口重要水庫(kù)取水口處鹽度均值為0.5‰時(shí)對(duì)應(yīng)的臨界大通流量。利用模型分析長(zhǎng)江口鹽度場(chǎng)對(duì)上游大通流量的敏感性。本文對(duì)臨界大通流量的計(jì)算研究有助于提高預(yù)報(bào)長(zhǎng)江口鹽水入侵模型精度,為長(zhǎng)江口水庫(kù)避咸蓄淡提供參考;鹽水入侵對(duì)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,
