Proceedings of the Meeting on Computational and Experimental Studies for Modeling of Radionuclide Migration in Complex Aquatic Ecosystems

Matsunaga, Takeshi; Hkanson, L.*

The Research Group for Environmental Science of JAEA held a meeting on computational and experimental studies for modeling of radionuclide migration in complex aquatic ecosystems during November 16-20 of 2009. The aim was to discuss the relevance of various computational and experimental approaches to that modeling. The meeting was attended by a Swedish researcher, Prof. Dr. Lars Hkanson of Uppsala University. The meeting demonstrated that it is crucial (1) to make a model structure be strictly relevant to the target objectives of a study and (2) to account for inherent fluctuations in target values in nature in a manner of qualitative parameterization. Moreover, it was confirmed that there can be multiple different approaches of modeling with relevance for the objectives of a study. These discussions should be considered in model integration for complex aquatic ecosystems consisting catchments, rivers, lakes and coastal oceans which can interact with the atmosphere.
