Progress in Water Quality Parameter Retrieval via Remote Sensing Technique Combined with Bibliometrics

Water is one of a fundamental natural resource and strategic compound. However, with socio-economic development, the water environment is being confronted with a series of problems such as aggravated pollution. Accurate monitoring of the water quality is the prerequisite and foundation for water environment supervision and governance. With the development of remote sensing and computer technologies, the retrieval of water quality parameters has attracted increasing attention from researchers and practitioners. This paper aims to present progress of remote sensing technique in water quality parameter retrieval methods and applications. The following aspects were investigated in this review: (a) water quality parameters retrieval data source; (b) water quality parameters retrieval models and evaluation metrics; (c) water quality parameters remote sensing retrieval applications; (d) some challenges and potential directions for water quality parameters retrieval. This review provides some support for re-searchers, as well as management departments, in theoretical research and application for remote sensing water quality parameters retrieval.
