The risk of algal blooms in landscape water bodies replenished by reclaimed water (RW) prompted the scientific management of RW discharge issues. Mathematical models are concise and convincing methods to stimulate algal growth and calculate thresholds for water quality control. This study presented three types of models, including one-parameter models, multiple-parameter models, and ecosystem dynamic models. Key influencing factors (such as nutrient concentration, light intensity, temperature, biotic processes, specific hydraulic conditions, etc.) are taken into consideration in these models. The work provided feasible methods for the management of reclaimed water to prevent water bloom outbreaks.
