Research On Production Dykes Of The Yellow River Floodplain In Shandong Province

Production dykes of the Yellow River floodplain in Shandong province are built spontaneously to reduce the loss caused by floods. Production dykes, to a certain extent, lessen the possibility of small and medium-sized floods and play an important role in protecting people's property and security. But at the same time, it also accumulated the great risk that cannot be ignored. Production dykes lower the chances of flood overflow, restrict the exchange of discharge and sedimentation between floodplain and main channel, increase the main channel deposition, lessen the main channel reduce power, and then flood threats increase. Production dykes experienced the process of building-breaking-building-breaking, which is still not solved properly.This paper mainly analyzes the natural geography and social economy of the Yellow River floodplain in Shandong province; analyzes the evolution process and tendency of production dykes; researches the production dyke influence on the distribution of sediment deposition and flood controlling; analyzes the flood routine changing and its traveling time. Using mathematical model research, simulating the flood flowing in different schemes, analyzing and calculating the typical "ChangPing Floodplain", this paper puts forward the comments and suggestions on production dykes of the Yellow River floodplain in Shandong province.Production dykes are related to river management and flood control, but also to people's work and daily life. They have both natural and social attributes. In the process of research, from the viewpoint of guaranteeing the safety of the lower Yellow River and people's life and property, this paper sticks to the scientific view of development and closely combines the actual situation of the Yellow River floodplain. With comprehensive analysis, scientific reasoning and far with recent goals, this paper puts forward reasonable suggestions on the management of production dykes in the Yellow River floodplain.
