【摘要】：鹽水入侵是河口地區(qū)較為嚴重的環(huán)境問題,對各用途用水都有一定影響。錢塘江河口作為杭州的主要飲用水源地,近年來受鹽水入侵影響較為嚴重。雖然2D和3D數(shù)值模型在鹽水入侵方面已得到廣泛應用,然而理論預測模型只需要較少的數(shù)據(jù)即可建立,更加快速高效。本文在Savenije一維鹽度平衡方程基礎上,建立了錢塘江河口(地形以指數(shù)形式衰減)漲憩和落憩時刻的鹽水入侵預測模型。我們采用2012年11月7—9日(小潮)和11月14—16日(大潮)時段的實測水文、鹽度數(shù)據(jù)對模型進行率定和驗證。結(jié)果表明,模型鹽度計算值和實測值吻合較好,并且通過模型計算得出錢塘江鹽水入侵長度也具有一定精度。
[Abstract]:Salt water intrusion is a serious environmental problem in estuarine area, which has certain influence on water use. Qiantang River estuary, as the main drinking water source in Hangzhou, has been seriously affected by salt water intrusion in recent years. Although 2D and 3D numerical models have been widely used in saltwater intrusion, theoretical prediction models need only a small amount of data and can be established more quickly and efficiently. On the basis of Savenije's one-dimensional salinity equilibrium equation, a prediction model of saltwater intrusion in Qiantang River Estuary (whose topography attenuates exponentially) is established in this paper. We use the measured hydrological and salinity data from November 7-9 (low tide) and November 14-16 (spring tide) to verify the model. The results show that the calculated values of salinity of the model are in good agreement with the measured values, and the length of salt water intrusion in Qiantang River also has a certain accuracy through the calculation of the model.
