Radioactive materials released into the air from the Fukushima nuclear accident weredeposited on the surface by the dry and wet processes. The deposited radionuclides on the soilsurface were adsorbed with soil particles and they infiltrated below the soil surface or transportednear the watershed by rainfall. In this study, RUSLE, Kinematic models and advection dispersionequation have been constructed to evaluate the behavior of radioactive material by soil erosion,hydrodynamics and transport in soil and river environment. The computed results were comparedwith measurements near the soil and river of the Fukushima area after the nuclear accident. Thecomparative results showed good agreements between simulations and measurements.

The computed results were comparedwith measurements near the soil and river of the Fukushima area after the nuclear accident. Thecomparative results showed good agreements between simulations and measurements.
