METHOD AND APPARATUS FOR CONSTRUCTING ONE-DIMENSIONAL HYDRODYNAMIC MODEL, ELECTRONIC DEVICE, AND STORAGE MEDIUM

The present application provides a method and an apparatus for constructing a one-dimensional hydrodynamic model, an electronic device, and a storage medium. The method includes: acquiring topographic data of a cross section of a riverway and hydrodynamic interpolation parameters; constructing a hydrodynamic interpolation table of the cross section of the riverway according to the topographic data and the hydrodynamic interpolation parameters, where the hydrodynamic interpolation table includes a water level-water surface width interpolation table, a water level-flow passing cross-sectional area interpolation table, a water level-hydraulic radius interpolation table, and a flow passing cross-sectional area-water level interpolation table; and constructing a one-dimensional hydrodynamic model of the riverway based on the hydrodynamic interpolation table of the cross section of the riverway. In the method provided in the foregoing solution, a one-dimensional hydrodynamic model is constructed based on a hydrodynamic interpolation table, so that the one-dimensional hydrodynamic model can determine a correspondence relationship between a cross-sectional hydraulic element and a water level in a table lookup and interpolation mode, thereby improving the calculation efficiency of the one-dimensional hydrodynamic model.
