Water quality monitoring is required to be managed on a regular basis for human consumption purposes. Water quality is currently analyzed in the laboratory or through in‐situ measurements. Although these measurements are accurate, they miss the spatial and temporal components needed for water body management. These are also expensive and time‐consuming procedures that cannot satisfy the monitoring needs on a large scale. Remote sensing technology can be employed for monitoring different water quality parameters (i.e. temperature, turbidity, and chlorophyll content). Thermal and optical sensors can retrieve spatial and temporal information required to monitor water quality and develop management practices. Remote sensing is also used to measure suspended sediments and chlorophyll concentrations spatiotemporally based on empirical relationships with radiance or reflectance (Ritchie and Cooper 1991; Ritchie et al. 1994).
