作者：

Highlights：

• Stochastic hybrid dynamic systems are used to model water quality evolution.

• Improved fruit fly optimization algorithm is proposed to identify the model parameters.

• Improved interacting multiple model filter algorithm is proposed to estimate hybrid state.

• Health degree of water quality is established to achieve health risk assessment.
