Implementation of Hydrological Dispersion Module of JRODOS for the assessment of 137Cs transport and fate in rivers, reservoirs and ponds of the Fukushima Prefecture

The Hydrological Dispersion Module of JRODOS was implemented for the predictions of the long term dynamics of radiocesium in the rivers and ponds of the Fukushima Prefecture and for the forecasting of radiocesium dynamics in the reservoirs under the influences of the extreme flush floods generated by the typhoons. The possibilities of HDM for the assessment of the efficiency of the potential remediation measures for the diminishing water contamination were tested for several water systems.
