| Abstract: | Many phenomena and findings have demonstrated that nuclide pollutants transform through the carrier of sediment. In this article, a one dimensional migration model of unsteady instantaneous nuclide emission in the sedi- ment of Zijiang river is derived by applying the theory of environmental science, hydraulics and the principle of sedi- ment engineering. The comparison between the models of unsteady instantaneous nuclide emission and continuous nu- clide emission is made in the last part. |
