摘要：In this paper, problems involving steady pollutantspread from a point source in a path with laminar water floware studied. Three different paths with different inclinationangles are considered. The problems are governed by diffusionconvection equations. These governing equations may not besolved analytically. Hence, in this paper a numerical methodcalled Dual Reciprocity Method (DRM) is employed to solve theproblems numerically. The numerical solutions are presentedto determine the effect or influence of inclination angles to thepollutant concentration in the water.
