This review, concerning on findings obtained by detailed field monitoring after the Fukushima Daiichi Nuclear Power Plant accident, covers the initial fallout and vertical movement of radionuclide in the land and forest, and subsequent transport and redistribution through hydrological and geomorphological processes in cropland, urban area, paddy field, and forested area. We discuss the finding of the transport of radionuclides through rivers and new discoveries for hydrological and sediment transport environmental impact in monsoonal regions.
