Research Of Flood Control Program And Level For Big And Medium Reservoirs In Beijing Workshop

Recently, because of drought, the problem that there is a lack of waterresource has been more and more serious in Beijing, but too many reservoirsstill be used in old rules, so water in the reservoirs is getting little and can notmeet to the demand of industry and agriculture. In the future, the pressure ofpopulation explosion and lackness of water resource will increase further. Sowe should study the new flood control level and attemper way of the Big andMedium Reservoirs in Beijing using of the new data and methods currently,and increase the capability of the reservoirs in the precondiction of safety,and that has important significance to mitigating the tension of water using inCapital.In this thesis, Miyun Reservior is analyzed mainly. The flood controllevel and attemper way of Miyun Reservior has been analyzed in severalmethods underground the new data. I check and ratify the flowing sheet waterand flood hydrograph firstly;calculate the flood control level by conventionalmethod firstly, and subsection the flood season, then analyze the flood controllevel of every period;bring forward the dynamical flood control level anddraw accordingly the curve that can be use of the limiting line of flood level,controlling dynamically the flood control level. Furthermore, I also study theflood control program of Miyun Reservior on considerding the cutting andstaggering flood function of reservoirs between the Miyun Reservior and theSuzhuang reference point. I contrast the result deduced from those ways anduse them together, what can increase markedly the accumulated storage ofMiyun Reservior in the condition of safety.In another part of the thesis, I discuss some methods in studying theflood control program of the Big and Medium Reservoirs in Beijing,including how subsection the flood season rationally, converting the originaldata into prevail, the feasibility of flood forecast on hydrometeorology. Inaddition, I emphasize that we should reckon with the advantage and limitingfactor of every reservior to flood control banding Guanting Reservior andHaizi Reservior.
