基于TOPEX/Poseidon卫星数据的江河流量测算
DOI: 10.11821/xb200401012, PP. 95-100
Keywords: 卫星测高,TOPEX/Poseidon,水位,流量,长江
Abstract:
TOPEX/Poseidon卫星的原始目的是测量海面高度变化信息，为海洋监测服务。作者通过假设基准面的方法，将由TOPEX/Poseidon卫星数据估算的下垫面水位相对变化信息转化为”水位”系列并建立了由TOPEX/Poseidon得出的“水位”与相邻水文站实测流量间的相关关系，进而实现了由TOPEX/Poseidon卫星数据估算河道流量的目的。利用1998~1999年TOPEX/Poseidon在长江下游大通附近的过境数据和对应年份大通水文站实测流量数据，验证了本方法的可行性。研究结果表明在长江下游河道地区，由TOPEX/Poseidon卫星数据可定量估算出河流流量信息。
