山区雨源型河流防洪现状及格宾网生态堤设计OA

River management is an important engineering measure to fill the gaps in flood control of rain source rivers in mountainous areas,reshape the natural ecology of the watershed,and create a harmonious and beautiful environment between humans and water.In response to the problems of low flood control standards,steep rise and fall of floods,and severe losses during flood season in Yangliu River section,this paper uses the rain flood method to calculate the design flood of the watershed.Based on the current flood control situation of the river section and the requirements of urban ecological landscape construction,a flood control reinforcement plan combining the construction of new ecological embankments and sediment dredging is proposed.The comparison results show that gabion net ecological embankment has good terrain and geological adaptability,as well as flood control and erosion resistance capabilities,and can reasonably restore and protect the ecological environment of the watershed,forming a virtuous cycle of"embankment water vegetation".
