—In this study, the physical disturbance in the river
estuary was discussed as the variation of hydrodynamic fields
caused by the human activities. We built the coupled model to
forecast the ecological risk with physical disturbance in the
different condition of temperature gradient. The temperature
gradient was one of the most important parameters to report the
growth circumstance of water ecological species, especially for
the biodiversity. The relationship between water temperature
gradient and the biodiversity was proposed by using the model
methods. When the gradient was higher, the biodiversity index
was increasing, which was considered as the optimal ecological
