潮汐影響區
英文
tide affecting zone-
Shipment traffic usually is heavy in littoral area, the navigation capability is required in many riverway. navigation lock was set to suit for the water level ' s variety caused by tide. for a long period, being lack of the quantified assessment on the influence of saltwater intrusion, approaches that freshwater is inpoured to the lock chamber are adopted lest the high concentration salt water be imported to the inland waterway, when the navigation lock is in operation. but such manner should not be reasonale enough
沿海地區船運發達，很多河道有通航要求，為克服潮汐造成的水位變化而設置船閘。長期以來，由於缺乏對鹽水入侵內河河道產生影響的定量評估，在船閘運行過程中為防止高鹽度鹹水入侵內河，通常採用將內河淡水打入閘室的方式來調節通航水位，船閘的這種運行方式不盡合理。Study achievement appears as following aspects : ( 1 ) yellow river estuary gate river flow and tide flow mixed area is not keep standing deposition status, on special income water and sediment conditions, boundary conditions and oceanic power conditions, this area may on the scour status ; ( 2 ) observed from estuary sediment deposition distributing process : delta and sea offing area sediment deposition vary trend is similar, each part sediment deposition scale varies as wave shape ; ( 3 ) on estuary gate, affect the sediment deposition factors, primary factors are tide prop, the gate widens gradually, estuary gate have branches, brine induced flocculation. this paper study the estuary gate widen, estuary gate have branches to affect the river channel deposition in quantity ; ( 4 ) based on field measured data, for the first time, deduce the estuary sediment deposition and distributing regress formula which can estimate estuary different areas sediment deposition volume ; ( 5 ) this subject demonstrate the estuary delta coastline dynamic balance conception, build the relationship between the estuary income sediment with deposition land area, draw the following important conclusion : when estuary years - averaged income sediment keeps at 345 million tons, the delta coastline may on the dynamic balance status. ( 6 ) this subject firstly brings up estuary sediment optimized control conception, and has the primary study on the macroscopically optimized control conception method
研究認為： （ 1 ）黃河河口口門逕流潮汐區域並非持續保持淤積狀態，在特定的來水來沙、邊界條件和海洋動力條件下，該區域可以處于沖刷狀態； （ 2 ）從河口泥沙沉積分配的過程來看：三角洲與濱海區泥沙的沉積變化趨勢是基本一致的，各部位的泥沙沉積比例變化基本呈波動狀態，且三角洲與濱海區泥沙的沉積比例與來沙量密切相關，基本成正比關系； （ 3 ）在口門處，影響泥沙沉淤的因素主要集中在潮汐頂托、口門逐漸加寬、河口門分汊、鹽水造成絮凝等，本報告主要對口門加寬，口門西妥理工大學工程碩士專業學位論文分漢對河道淤積的影響進行了定量分析: （一扣根據實測資料首次建立了河贖流路泥沙沉積分配的回歸計算式，據此可以預估計算河口不同區域泥沙的沉淤量; 、 5 ）本項研究首次論證了河口三角洲岸線動態平衡的概念，並建立了黃河河口來沙量與造陸面積的相關關系，得出了當河口多年平均來沙量維持在3 . 45億t時其河口三角洲岸線則可能處于動態平衡狀態的重要結論; 『 6 ）本項研究首次提出了河口泥沙優化調控的概念，並對其宏觀優化調控模式進行了初步探討。This has been further complicated by undisinfected effluent discharged from stage 1 of the harbour area treatment scheme hats since late 2001. though the scheme has brought about general improvement in the harbour s water quality, particularly the eastern side, the discharge is released from a tunnelled outfall from the stonecutters island sewage treatment works, situated around eight kilometers from many of the beaches. tides and currents have resulted in the hats discharge affecting beach water quality in the tsuen wan district
此外，凈化海港計劃第一期工程已於2001年底完成，該計劃雖能為海港整體水質帶來顯著的改善，特別是東面水域，但昂船洲污水處理廠尚未設置消毒設備，而海底排污渠口則距離荃灣多個泳灘僅約8公里，處理后的污水往往隨潮汐和海流進入荃灣水域，影響區內泳灘水質。Internal waves are a kind of bridge relating the diapycnal mechanical mixing to external sources of mechanical energy : first, internal waves are driven by wind stress and barotropic tide so that large amount of mechanical energy are transported to abyssal ocean with propagation of internal waves ; second, the mechanical energy can directly be cascaded to mixing through instability and breaking of internal waves
內波是外界提供的機械能與混合之間聯系的橋梁之一，一方面風和潮汐通過激發內波，將能量向深海和大洋內區傳遞，另一方面，內波的不穩定和破碎直接將機械能串級到小尺度湍流混合中去。開展傾斜地形上內波的傳播以及內潮的產生等方面的研究對海洋混合過程的參數化以及混合對大洋環流的影響等方面的研究具有重要的科學意義。The quality factor is about 9543, which, compared with those determined based on the tidal gravity observations in the previous studies, more closes to those obtained by using the vlbi data. the complex resonance strength is ( - 6. 10x10 - 4, - 0. 01x10 - 4 )
以武漢臺超導重力儀觀測資料為例，研究了海潮負荷對fcn共振參數擬合的影響和重力潮汐觀測中近周日共振的區域性特徵。Two were faced in common with other areas around hong kong : namely, waste runoff from pig farms in the vicinity and extensive discharge of raw sewage from squatter areas and other developments lacking adequate sewage facilities. the third, however, related to the specific geography of the tsuen wan coastline. tides frequently brought polluted marine water from the rambler channel between tsuen wan and tsing yi north - west along the line of coast where the gazetted beaches are located
1980年代，荃灣區泳灘主要受到三個污染源影響，其中包括附近豬場排放的污染物，以及寮屋和樓宇排放未經處理的污水，這兩個污染源是全港泳灘普遍面對的問題，至於第三個污染源則是由於荃灣海灘位於藍巴勒海峽荃灣與青衣島之間的海峽的西北方，常有受污染的海水隨潮汐流到荃灣的泳灘。Effects of sea tide should be considered in modeling groundwater dynamics and associated contaminant transport in coastal aquifers, which may result in significant increase of computing time especially for variable - density contaminants, and superior numerical performance of the model is required
摘要模擬沿海地區地下水及污染物的輸移需要考慮海洋潮汐的影響，對于變密度污染物，考慮潮汐的影響會大大增加模型計算量，模擬此類問題要求模型具備優良的計算效果。分享友人
