| Outline of Final Research Achievements |
This study aimed at the development of a framework for simulating the dynamics of water flows and fish behaviours in irrigation channels and rivers. We conducted a series of field surveys and numerical analysis on fish ecohydraulics, in which advanced measurement methods such as acoustic Doppler current profiler (ADCP) were employed to measure high resolution hydrodynamic data. Data-driven models using machine learning were employed for modelling fish species distributions and its dynamics. Process-based models were used for modelling 1D or 2D hydrodynamics in the target reach, based on which habitat heterogeneity was assessed in order to link it with species richness.
