Abstract
In order to fill the information gap in the distribution and storage of reservoirs in China,this article compiled a list of reservoirs in a small river basin and estimated the seasonal water storage changes of reservoirs in 2000 and 2018 using remote sensing observations.The research area includes 149 reservoirs,of which 102 are existing reservoirs built before 2000,and the other 47 are new reservoirs built between 2000 and 2018.It monitors the reservoir using surface reflectance data from a Moderate-Resolution Imaging Spectrometer(MODIS)and detects the presence of the reservoir by analyzing Normalized Differential Water Index(NDWI)time series.In order to estimate the water storage changes of all reservoirs,the inundation range of reservoirs retrieved on Google Earth Engine(GEE)platform was combined with coastal terrain information obtained from the DEM data of the space shuttle radar terrain mission.Through this study,we can gain a more comprehensive understanding of the distribution and seasonal changes in water storage capacity of reservoirs in a small river basin.关键词
