The Application Of Ecological Hydronics In Modern Riverway Treatment

Riverway treatment is a traditional and pragmatical engineering of an ancient and active field. Since the 70s of last century, the relation between hydraulic engineering and river ecosystem has drew a lot of attention from the international scientific and technological field and has become a hot topic in enviromental field. People have made many analyses on the the bad effects of hydraulic engineering to river ecosystem from different viewpoints and have established the theory and engineering practice of river ecosystem recovery upon these analyses. The theory and practice of Ecological hydraulics came into being. Through the collections and studies of domestic and international application cases of ecological-hydraulic riverway treatment, the main ideas of this essay are as follows:This essay puts forth the urgency of the application of ecological hydraulics upon the present researches of the theories, methods and applications of domestic and international ecological hydralic engineering; it makes a summary of the bases, models and principles abode by the ecological hydralic riverway treatment; it states that the ecological hydraulic engineering theory should be applied in riverway treatment; it sums up several common methods of ecological riverway treatment: first, to construct ecological river banks with the aim of benefiting human beings; second, to construct rivers of biodiversity. Upon the ecological riverbank models, this essay presents several correponding methods of protecting banks, probes some important issues of ecological riverbank construction and gives a summary. The essay makes a comparison and an induction for the rivers of biodiversity, and also gives a detailed introduction for the construction of rivers of biodiversity.Lastly, after a summary of the dangers caused by the former concrete structures, with the concrete explanatory riverway treatments of South Fei River Scenary Treatment Engineering of Hefei City, this author explores some ideas of the engineering and design of South Fei River:the satisfation of flood prevention and effluent, the requirements of ecosystem and scenery, the combination of flood prevention, flood effluent and environmental treatment, and provides certain practice bases for the application of ecological hydralics in riverway treatment.
