| Abstract: | The mathematical model of the water-salt transport of trapezoid canals bottom soil is established, using the hybrid Laplace transform finite element method, the water salt transport of the trapezoid canals bottom in process of immersion beforehand are analyzed. The results show that hybrid Laplace transform finite element method is robust, reliable, and precise, the method can solve the water salt transport equation of the trapezoid canals. |
