The objective of this study was to modeling a effect of hydrodynamic characteristics on water quality and algal bloom using a three-dimensional (3D) model that could reflect the complex physical properties of a shallow reservoir. In this study, we also tried to establish a method to predict a algal bloom and algal-derived taste and odor compounds 2-MIB and geosmin. Water quality, phytoplankton, and taste and odor compounds monitoring was conducted at the Jinyang Reservoir in 2016. A 3D hydrodynamic model was coupled with an ecological model to predict cyanobacteria bloom and the presence of taste and odor compounds. The results showed that the simulations of taste and odor compounds spatial distribution and occurrence time were realistic; however, the concentration of geosmin was overestimated when Microcystis sp. was blooming. The model can be used as a management tool to predict the occurrence of algal taste and odor compounds in reservoir systems and to inform decision-making processes concerning dam operation and water treatment. |
