Resumo

Due to the nuclear-power plant accident after the 2011 Great East Japan Earthquake and Tsunami, the residents who had resided within 20 km from the Daiichi Fukushima Nuclear Power Plant had forced to leave their hometown. Japanese government agencies have measured the level of radioactive contamination in urban, agricultural area, forest, riverine and ocean. The impacts by the radioactive contamination extended in food, economy, civil engineering, community rebuilding, etc. and the research findings indicated that the level of 137Cs is higher in the forest than opening area such as paddy field or town of rural area, especially, litter layers and surface layers are significantly contaminated. The study calculated the estimation of contaminated soil erosion using the USLE which idea based on what if 137Cs would carry out from the forest after intensive rainfall. Predicting radioactive contaminate areas after intense rainfall is a significant issue for the future watershed risk management.
