Abstract
A simulation method of a surface water movement process in surface irrigation, comprising: acquiring surface relative elevation data, border surface roughness coefficient data and surface water infiltration rate data of a target border check; substituting surface relative elevation data, border surface roughness coefficient data and surface water infiltration rate data into improved full hydrodynamic equations, and performing numerical solution on improved full hydrodynamic equations to obtain a simulated surface water depth value and simulated values of vertical integral average velocities of an irrigation water flow in x-coordinate and y-coordinate directions of a certain measurement site in the target border check at a certain time; and obtaining simulated values of unit width discharge of the irrigation water flow in x-coordinate and y-coordinate directions, respectively according to simulated surface water depth value and simulated values of the vertical integral average velocities of the irrigation water flow in x-coordinate and y-coordinate directions.
