鄱阳湖水动力模型的遥感验证研究
Study on hydrodynamic model validation by remote sensing in Poyang Lake
摘要
Abstract
Hydrodynamic process in Poyang Lake from 2009 to 2011 was simulated by using the lake hy-drodynamic model , EFDC.Results showed that simulated daily average water elevation and discharges consisted with hydrologic station observations and the correlation coefficients are all above 0.94.Remote sensing data were employed to validate and analyze the model practicability more comprehensively in or -der to solve the problem of data deficiencies .The water surface height and inundation area measured by Radar altimeter ENVISAT RA-2 and MODIS images correlated with numerical simulation resultswith a correlation coefficient higher than 0 .83 , which indicated that thefrequently changingwater dynamic char-acteristics in Poyang Lakecould be effectively revealed by using EFDC model .Furthermore , remote sens-ing techniquesalso providedtheory for long -termvalidation from different perspectives .关键词
