在过去的二十年中，遥感数据在推进洪水淹没建模方面取得了巨大进展。特别是，低成本的星载数据对于数据稀缺地区的大规模洪水研究非常宝贵。各种卫星产品可提供有价值的信息，例如地表海拔、洪水范围和水位，这些信息可能有助于各种洪水研究。越来越多的研究致力于探索这些低成本数据，用于构建、校准和评估，以及将遥感信息同化到水力模型中。本文旨在回顾最近将低成本星载遥感数据与洪水建模相结合的科学努力。讨论了这些数据在洪水建模中的潜力和局限性。本文还介绍了未来的卫星任务，并预测了它们对洪水建模可能产生的影响。版权所有 © 2015 约翰·威利父子有限公司
During the last two decades, remote sensing data have led to tremendous progress in advancing flood inundation modelling. In particular, low‐cost space‐borne data can be invaluable for large‐scale flood studies in data‐scarce areas. Various satellite products yield valuable information such as land surface elevation, flood extent and water level, which could potentially contribute to various flood studies. An increasing number of research studies have been dedicated to exploring those low‐cost data towards building, calibration and evaluation, and remote‐sensed information assimilation into hydraulic models. This paper aims at reviewing these recent scientific efforts on the integration of low‐cost space‐borne remote sensing data with flood modelling. Potentials and limitations of those data in flood modelling are discussed. This paper also introduces the future satellite missions and anticipates their likely impacts in flood modelling.
