More and more activities have caused significant damage to the river environment, among which a typical problem of blocked fish migration is constantly attracting people’s attention. Nowadays, fishways are essential hydraulic facilities solve such problems. Although different fishway has particular blocking effect on water flow, flow velocity vital positions in could still be relatively high lo...

Understanding how migratory animals interact with dynamic physical environments remains a major challenge in migration biology. Interactions between migrants and wind water currents are often poorly resolved models due to both the lack of high-resolution environmental data, understanding respond fine-scale structure environment. Here we develop generalizable, data-driven methodology study throu...
