In this study, we deployed smart sensors throughout the Nanhua Reservoir watershed to collect longterm
hydrological and sedimentary data for effective management of sediment transport. By integrating smart sensors
with established maintenance procedures and standardized data-processing workflows, sediment fluxes during extreme
weather events, such as typhoons, can be consistently recorded and accurately represented, supporting a detailed assessment of the watershed’s sediment budget. The resulting real-time and long-term data sets provide a robust foundation for developing sediment-management strategies, optimizing dredging operations, and designing sediment-retention and trapping infrastructure. Overall, our study guides data-driven decision-making for watershed conservation, reservoir sustainability, and sediment yield mitigation.
