| Abstract: | The orthogonal boundary-fitting coordinate system and physical fractional stepmethod are used to establish a mathematical model for 2-D flow field in natural river course.Theresults from some calculated examples indicate that this mathematical model is very effective forthe numerical solution to flow fields in river course with the complicated boundaries and that thismathematical model can be used in engineering practice. |
