Preliminary Research On Planning And Design Of River Based On Ecological-Hydraulic Engineering

Eco-hydraulic engineering is the only way to develop modern hydraulic engineering, which h as been widely studied in recent decades. Drainage, impoundment and conductivity should be the main functions of hydraulic engineering projects, when achieving these basic functions, more attentions should be paid to maintaining the natural features of water environment and p rotect the survival of aquatic life and amphibian creatures as much as possible. Eco-hydraulic engineering and Eco-river construction has been the main trend of modern hydraulic enginee ring, most of theory studies and practices about eco-hydraulic engineering and eco- river cons truction have made great achievements at home and abroad. Although eco-hydraulic engineer-ing has been developed in recent years in China, but still in its infancy. Eco-hydraulic engine ering projects in China mainly focused on the goal of building, which always ignoring the eco logical functions of water environment, especially in the river constructions.Based on the research achievements about eco-hydraulic engineering and eco-river const ructions, this paper analyzed and summarized the basic knowledge frame of eco-hydraulic en gineering and eco-river constructions. It concluded that ecological river construction is one of the sub-geneses of Eco-hydraulic Engineering, and then use the knowledge of eco-engineering to study the eco-river constructions in order to construct eco-river project. Based on the knowledge and projects of eco-hydraulic engineering and eco-river, this paper study the eco-embankments we are know and improve the gridding form of revetment and put forward a new grid form about revetment which could be used in many ways such as riverbed, barrage and so on. Those three different types of revetment will be designed again and used in different watercourse. About those three types of revetment, it considers the function of control flood, ecological function and the value of microlandschaft too, and we hope that it could help the project of management about the eco-hydraulic engineering and eco-river.
