| Abstract: | By using 2?D river regime?fitted orthogonal quadrilateral grid to divide calculating zones and through limit volume method to separate the control model equations and their given solution conditions, with SIMPLE algorithm method in solving equations numerically, the 2?D mathematic model for sediment and erosion calculation of river channel under boundary layer coordinates was presented. This model was employed in simulation Wuhan reach and was verified by measured data. Its applications in other projects were also proved reasonable. |
