Abstract : the qiantang estuary with violent hydrodynamic conditions is well known for its tidal bore. the regulation of the estuary in the past, especially the progress since the founding of new china are reviewed. the principles of the regulation and planning of the qiantang estuary formulated in 1960s are expounded, i. e., to narrow the river to reduce the tidal prism, and to increase the ratio of the river flow to tidal discharge. the experience of estuary regulation / reclamation is summarized, especially the engineering measures to protect the groin head and to use polder dykes as sea defense works. finally, the effect is analyzed of the large - scale constraction / reclamation in the estuary on the tides, flooding high water level, estuary bed and the northern deep waterway in the hangzhou bay

正是基於這種考慮，本論文結合廣州市三防指揮系統工程和廣州市水利信息化工程的建設，本著理論性與實用性相結合的原則，從可持續發展的角度，重點研究以下內容： 1 、廣州市主要河流洪水發生的規律及存在問題與防洪措施； 2 、廣州市現有防洪措施的防洪標準與可靠性； 3 、洪水預報與調度系統的方法與技術路線； 4 、現代防洪管理。Meanwhile, the flood peak fell off ceaselessly, witch indicates that the new conformation descended greatly
Sin以上，這比現代洪水時期河水位一般上升1 zm左右明顯高。( 2 ) in the chapter two, several general plannings of huai river catchment are discussed and successful and failing experiences are also summarized on the flood protection of huai river. ( 3 ) in the chapter three, the executive practice is analysed on the adjusting and regulating planning of huai river middle courses for flood protection
第二較為詳細地總結了新中國成立以來，淮河流域幾次規劃的成功經驗與存在的問題，分析了五十年代治淮方略及其骨幹工程為淮河防洪奠定的良好基礎；同時指出六十年代、七十年代治淮工作指導思想中存在的問題。First the author memorized the yellow river excavation history and concluded development of modern dredging science, and found that most researches of dredging are related to navigation regulation, little used to flood control especially in the yellow river with silty. based on the experiment of generalized physical model of the lower reach of the yellow river, and the study of the loaden flow mechanism and the dredging efficiency, the author get some new ideas as follows : 1
通過對黃河疏浚的歷史以及現代疏浚工程學的發展進行了回顧和總結，認為已有的疏浚研究大多基於航道疏浚工程，對于防洪疏浚特別是在黃河這種多沙型河流上進行防洪疏浚的研究極為欠缺，本文基於黃河下遊河道概化模型試驗，對疏浚挖槽后水沙運動機理及效果等進行了研究，得到以下認識。After wto accession of china and coming of the new century, global ecology and environment are deteriorating severely. as economy of china continued developing, consumption of natural resources was increasing, the quality of forestry resources degraded, the functions of forest ecology were gradually weakened, disastrous floods occurred in the yangtze river, songhua river and nenjiang river. meanwhile, floods also happened in the hunhe river systems of liaoning province in the 1990s of late 20th century, and droughts in western regions of liaoning have threatened the whole province
隨著中國加入世貿組織及新世紀的到來，面對全球性生態環境的不斷惡化以及由於我國經濟持續地高速發展，對資源消耗過快過人，使森林資源品質不斷下降，森林維持生態平衡的功能的作用逐漸削弱，不僅我國三江連續發生洪水，西北乾旱加重，黃河多次出現斷流，遼寧在20世紀90代的渾河水系也曾發生過水災，遼寧西部乾旱日趨加重，已經威脅到整個遼寧。To prevent flood, adopting non - project measures is feasible and efficient marching measures in recent years in most of counties, adequately utilizing modern science and technology such as computer, information processing, net and communication, system emulation, artificial intelligence and so on to build system that can automatically survey and forecast water information, now plays a important role in grasping the information of rainfall, water and project, in making and selecting preliminary draft of flood control and dispatch, which can greatly raises the efficiency and flexibility of flood control, and has important realistic significance and social economic benefits in minimizing flood disaster
充分利用現代科學技術，如計算機、信息處理、網路和通訊、系統模擬、人工智慧等技術，建立水情自動測報系統，對雨、水、工情的掌握，防洪調度預案的制定、選擇和實施都有重要的使用價值，可以大大提高防洪工程措施的防洪效能和防汛調度的靈活性，對減少洪水災害具有重要的現實意義和社會經濟效益。鬱江洪水預報與調度系統內容豐富，主要有： 1 、系統設計； 2 、系統洪水預報模型； 3 、系統實時校正模型； 4 、系統河道洪水演進模型； 5 、系統水庫調度模型。My love for tsinghua university - in honour of mei yi - qi, the former president of tsinghua university written by wu hong - cheng recently, a professor from the college of education in hebei university, introduces to readers modern higher educationist mei yi - qi and the development of tsinghua university in difficulty from a new point of view and by means of an unique plotting
