Integrated watershed modeling for simulation of spatiotemporal redistribution of post-fallout radionuclides: Application in radiocesium fate and transport processes derived from the Fukushima accidents
We propose a new simulator to assess environmental impact of fallout radionuclide. Simulation treats surface and subsurface fully coupled hydrological processes. Spatiotemporal variation of the deposited 137Cs can be successfully reproduced. Deposited 137Cs is predominantly transported with the suspended sediment. Results indicate that most of the deposited 137Cs remains within the catchment.
