Question:
I would like to predict of radiocesium activity in fish and water in the future using the ERICA Tool. How can I do this?Answer:

Currently, you cannot input time series data, or data for more than one location, into the ERICA Tool to model in a single run. This functionality is something which has been requested previously by users and it MAY be provided in future Tool versions.

How you can best proceed depends upon what you want to do to some extent. Here are two suggestions:

1. As you are only considering Cs-137 you could extract the DCC values and if required Kd and CR values from the Tool and use them in an Excel spreadsheet. If you do this then make sure you check calculations by running one or two through the Tool as well as your spreadsheet

2. If you have multiple entries for a single year you could use Tier 3 to input mean values with an associated pdf.

On a different note, it looks like you have access to a large and potentially useful dataset, please consider making this available to the IAEA working group who are collating transfer parameter values for wildlife.
