Study On Water Allocation And Scheduling Regulation Scheme Of Huaibei Nanhu Lake Fountainheadin Huaibei

The conflict between water supply and demand is becoming increasinglyprominent in Huaibei because of iThe nsufficient water resources and its grossamount extremely uneven distribution of water resources in Huaibei City is lack ofdemand,and the time-space distributions is very uneven,together with and severewater pollution,the contradiction between water supply and demand is gettingincreasingly prominent,which has become the constraints ofrestricted the localeconomic and social development. Huaibei City is an one of the important coalbases in our country, but a lot ofover exploitation of coal resources has not onlydestroyed partly undermines the groundwater system and dewatering makengroundwater dried to some extent,but also bringsraught about appearance of a largenumber ofmany coal mining subsidence areas.In order to control overexploitation of In this paper, for the situation of thegroundwater overexploitation and deal with shortage of water resources in Huaibeilack, combined with the governance and utilization of coal mining subsidence,utilization of rainfall and flood resources in the Nanhu Lake, the biggest coalmining subsidence area in Huaibei, was studied in this dissertation, which couldimprove the utilization efficiency of surface water resources in the city. we regardNanhu lake—the biggest coal mining subsidence in Huaibei City as the researchobject, and study the utilization of coal mining subsidence from the perspective ofwater resources. Available amounts of water diversion and water supply of NanhuLake under different conditions were estimated by taking The storagethe lake’scapacity of Nanhu lake can be used as storage and flood resources can be fully usedto improve utilization of surface water resources in Huaibei City.as adjustment. Tostudy water diversion and available water supply of Nanhu lake under differentconditions is toThe study results could provide a reference to for “The Huai RiverDiversion Project” and the operation scheme of Nanhu lake. The data used in thepaper is based on relevant planning such as the overall urban planning of HuaibeiCity、water use planning of Huaibei City and hydrological data of precipitationstations of Xiaoxian, Suixi, Zhangzhuangzhai and Xulou. Based on the data, we can Available amount of figure out water diversion and available water supply ofNanhu Lake without consideration of water quality limitation were figured out byadjusting calculation and water balance analysis without regard for water qualitylimit. While taking account of water quality, the SMS model was used to simulatethe velocity field and pollutants transfer situation in the lake after water diversion,and the corresponding restrictions for safe water diversion based on different waterquality were also concluded in the dissertation.The available water supply of Nanhu Lake area in the current year and theplanning year at different guarantee rates were calculated in the dissertationwithout consideration of the diversion water quality, and the amounts could relieveshortage situation of local water resources to some extent. The study results alsoshowed that the actual water diversion took only a little proportion of availablewater supply. When the diversion water quality should be considered, thecorresponding water diversion restrictions were simulated by the SMS model,which showed that large water diversion restriction appeared when the diversionwater quality only met the standard of local water quality management objectives.And the storage capacity should be enlarged and the diversion water quality shouldbe improved so as to fully utilize the local water resources. The study results of thedissertation could provide relevant scientific reference for the diversion program ofthe Nanhu Lake.
