A number of mathematical models of predicting future distribution of radioactive contaminants, with particular attention on cesium, on the land and in rivers, lakes, and estuaries is developed and applied for the environments of Fukushima. For examples, a model comprises of the Universal Soil Loss Equation and the Geographical Information System is developed for predicting future distributions of soil and cesium on land and the one-dimensional river model, TODAM is provided for rivers and lakes. The iRIC/Nays2D model is used for predicting detailed distributions of soil and cesium in rivers in a two dimensional configuration and modified versions of ROMS and other models are examined for the sediment transport in estuary of ocean in a three dimensional configuration. In this article we present an outline of our current activities.
