Remote sensing technology-based re-checking of reservoir storage capacity curve of Zhelin Reservoir
摘要
Abstract
Aiming at the problems that the conventional method for re-checking of reservoir storage capacity curve is time-consuming,strenuous,highly costed,etc.,the reservoir water-body area is extracted,by taking Zhelin Reservoir as the study case,with 71 remote sensing images of Landsat satellite on the basis of the remote sensing technology-based extracting method for waterbody information,and combined with the measured water level of the reservoir when the images photographed,then the water level-area curve of the reservoir within the elevation range of the dead water level and the normal storage level is fitted according to the relevant statistic principle.Thereafter,the accuracy of the new storage capacity curve is verified from the aspects of the dimension of the remote sensing image adopted,water-body area measurement,curve alignment,accuracy of water level value,image resolution,etc.Compared with the original storage capacity curve,the storage from the new storage capacity curve is averagely larger than that from the old one by 4.16％ under the condition of the water level of 52 ～65 m measured in 1979-2016.Through the relevant verification,it is indicated that the obtained new curve meets the requirement of the operation of the reservoir,thus can provide a reliable basic data for the flood control and power generation operation of Zhelin Hydropower Plant.The remote sensing technology-based method for re-checking of reservoir storage capacity curve is cost-saving,fast and efficient,accurate and reliable,and then has a large popularization and application prospect.关键词
