The Fukushima Dai-ichi Nuclear Power Plant (FDNPP) incident, triggered by the Great East Japan Earthquake and subsequent tsunami in March 2011, resulted in the release of significant quantities of radionuclides into the terrestrial and marine environments of Fukushima Prefecture. While the activity of radiocesium (i.e., 
Cs and Cs) in these environments has decreased since the accident, continuous inputs through rivers draining and eroding the main terrestrial radioactive plume have been measured, maintaining elevated levels of Cs in riverine and coastal sediment deposited off the Prefecture's coast. Consequently, identifying the sources of sediment is required to elucidate the links between terrestrial and marine radiocesium dynamics and to anticipate the fate of persistent radionuclides in the environment.

We developed physically-based watershed models based on the distributed hydrological-sediment transport model. The model implementation for the experimental plots in Fukushima prefecture was conducted for particulate Cs transport. Also, we developed model that combines the watershed empirical models based on the washing-out coefficient approach and GIS data. The model was tested on the basis of the measurements of Cs concentration in Abukuma river and validated also on the basis of the data sets of radionuclide transport in the Pripyat and Dnieper rivers.
