This paper analyzes the cause of floods of bao river and hui river drainage basin in suixi and puts forward engineering measures and non - structural measures of flood control 摘要文章分析了濉溪縣包澮河流域的洪災(zāi)成因,提出防洪減災(zāi)的工程措施和非工程措施。
In order to reduce the economic losses due to water shortage , it is necessary to evaluate the risk of water shortage , and manage the risk by a series of structural and non - structural measures based on the evaluation 受降雨、徑流及其它各種隨機因素的影響,供水和需水都會不同程度地存在許多不確定性因素,因此,我國大多數(shù)地區(qū)出現(xiàn)水資源短缺風(fēng)險是必然的。
Dynamic control of the limit water level belongs to non - structural measures of reservoir operation . with the analysis of the cause and rule of flood in the catchments and taking advantage of hydrology and metrology information , the operable method can be obtained which not only satisfies the flood prevention but also takes full advantage of flood resources , and the upper and lower limits of the limit water level are determined with serial hydrology calculation . then , the rule of using the upper and lower limits is put forward to reach a beneficial flood operation with small risk 汛限水位動態(tài)控制方法屬于水庫風(fēng)險調(diào)度的非工程措施范疇,通過分析流域洪水的成因和庫區(qū)降雨及致洪規(guī)律,結(jié)合水庫的蓄泄能力,積極慎重的利用水文氣象預(yù)報信息,研究既能滿足防洪要求,又可充分利用洪水資源的可操作性的調(diào)度方法,利用水文系列的連續(xù)演算方式推求汛限水位的變化范圍,提出使用汛限水位上下限的原則,達到風(fēng)險較小、效益較大的目的。
