Résumé

Presented are results of Subproject 3c of the Project 2 "Radioecology" of Franco German Initiative on Chernobyl aiming at creating of database on radionuclide transfer by surface runoff in heavily contaminated areas of Belarus, Russia and Ukraine after the Chernobyl accident. Detailed information about 65 experiments on runoff plots in 30 km zone is collected. Data on general characteristics of contaminated watersheds and characteristics of their contamination, data on radionuclide concentrations in 17 small rivers and 5 large rivers together with hydrochemical characteristics are included in database. The database provides an opportunity for development of specific scenarios for model testing and validation, calculation of key characteristics of radionuclide wash off from contaminated watersheds, increased understanding of contaminant transport at the process level, and development and use of methods for estimation of key parameters.
