A river ecological flow optimization method based on three-dimensional flow field simulation

Abstract

The present application relates to the technical field of computer-aided design, in particular to a river ecological flow optimization method based on three-dimensional flow field simulation. The specific implementation process comprises: obtaining river data, extracting river basin boundary and constructing river flow field simulation model; performing fluid dynamics solution to output vortex structure, introducing bottom water flow momentum to extract hydrodynamic characteristic flow; constructing simulation fluid matrix to calculate swimming work consumption, and delineating river ecological zone to obtain three-dimensional ecological flow volume; monitoring spatial form fluctuation curve, converting global optimal ecological flow into water conservancy facility flow scheduling instruction output. The present application depicts the river bottom vortex structure and microscale hydrodynamic characteristics in the digital space by constructing the river flow field simulation model, improves the fine degree and physical reality of the flow field simulation, and improves the automation level, continuity and decision accuracy of the ecological flow determination by deeply coupling the hydrodynamic characteristic flow and biomechanics parameters.
