Summary

Before running a calculation code, it is necessary to collect and select the required entry data, data being a fundamental element upon which reasoning as well as research are based. In order to be rigorous, these practical elements should be managed in parallel with the modelling activities, aiming at common targets. For example, such a view is necessary for building relevant experimental designs. Indeed such methods require the collection of measurements through formalised protocols meeting the needs of the code. Such measurements could then define, for given space and duration, relevant data sets to "feed" the code. However, the calculation codes are frequently supplied a posteriori on the basis of measurements collected for other purposes. At first, the corresponding raw information must be collected and then adapted to the model needs, meaning a transformation of measurements into elaborated data. At this stage three kinds of problem exist: access to data, quality of data and quantity of available data. These issues are exposed here as part of the CASTEAUR project (simplified calculation of radionuclides transfer in receiving waterways), actually developed at the IRSN.
