AI Technical Summary
Existing technologies lack satellite-based methods for monitoring stratified runoff across river cross sections, which cannot meet the needs of monitoring pollutant fluxes during sudden pollution events. They also have low vertical stratification capabilities, cannot analyze vertical stratification phenomena in water bodies, and have limited monitoring range and high costs.
By using drones and sonar detectors to acquire river cross-sectional morphology and combining it with satellite remote sensing data, a three-dimensional hydrodynamic model is used to monitor river runoff in layers. The flow rate is calculated using the discretized momentum equation and hydrostatic pressure formula. By combining roughness inversion and iterative optimization of the velocity field, accurate monitoring of river cross-sectional flow can be achieved.
It enables the rapid construction of remote sensing runoff monitoring stations in areas without existing stations, accurately characterizes vertical stratification of water flow, optimizes eddy and turbulence simulation, provides long-term reliable flow data, and improves the basin's ability to control pollutants and monitor water resources.
