Within the framework of nuclear accident scenarios, the initial contamination of continental hydrosystems is essentially from surface deposition of atmospheric aerosols. Whereas the deposition velocities were recently widely studied for meadows, forest and urban forest canopies, the aerosol deposits on hydrosystems need more specific investigations. The present work concerns the first step of a study on the mechanisms of dry deposition of sub-micro aerosol on continental hydrosystems (rivers, lakes and wetlands).
