| Abstract: | In this accompanying study,we compare and analyze the differences in stability,convergence,precision and efficiency resulting from the use of two methods in the solution of the one-dimensional model for coupling surface water flow with solute transport for border fertigation(1-DMCSWFSTBF).The first method is the hybrid numerical method,while the second one is the Roe finite volume method.Results show that the hybrid numerical method produces better numerical stability and convergence compared to the Roe fin... |
