Abstract

Remote sensing techniques can be use to monitor water quality parameters (i.e., suspended sediments-turbidity, chlorophyll, temperature). Optical and thermal sensors on shoreline booms, boats, aircraft, and satellites provide both spatial and temporal information needed to monitor changes in water quality parameters for developing management practices to improve water quality. Recent and planned launches of platforms equipped with improved spectral and spatial resolution sensors should lead to greater use of remote sensing techniques to assess and monitor water quality parameters. Integration of remotely sensed data, GPS, and GIS technologies provides a valuable tool for monitoring and assessing waterways. Remotely sensed data can be used to create a permanent geographically located database to provide a baseline for future comparisons. The integrated use of remotely sensed data, GPS, and GIS will enable consultants and natural resource managers to develop management plans for a variety of natural resource management applications. This review paper identifies current knowledge regarding the assessment of water quality, and identifies promising techniques for high resolution assessment.
