An investigation into the particle volume scattering function variability in a cascading reservoir system
This work analyzed the spectral and spatial distribution of the particle volume scattering function, bp, in a cascading reservoir system. During fieldworks water quality parameters and scattering data were sampled in a predetermined stations. The bp was estimated using the ECO BB9 equipment that measures the volume scattering function, b at 117deg [b(117deg) The estimated bp(117deg) were compared with the remote sensing reflectance, Rrs, and the chlorophyll a (Chl a) concentration, total suspended matter (TSM) concentration and the transparency (measured using a Secch disk) The results showed that in a hypertrophic environment the bp is dominated by the phytoplankton scattering and in an oligotrophic water system, the scattering by a suspended matter dominates. The bp(117deg) variability from a hypertrophic to an oligotrophic aquatic system affects the remote sensing reflectance (Rrs) spectral shape. Due to this, the parametrization of a unique bio optical model to estimate the optically active components in the water will be challenging.
