SMEDIS was a research project funded by the European Union under the Environment and Climate Research Programme for the period 1996-1999.

The project was coordinated by the Health and Safety Executive (HSE, UK) with two other main partners: Cambridge Environmental Research Consultants (CERC, UK) and Electricité de France (EDF, F).

Ten additional partners from across Europe also participated in the project.

The main results of the project is first a methodology for the evaluation of dense gas atmospheric dispersion models used in the study of accidental releases of explosive or toxic materials. This evaluation is composed of a scientific assessment of each model, together with a validation by comparison with available experimental data. An additional output is a database of dense gas dispersion experiments that has been used in the course of the project and can be used for future validation.
