Study of accidental rejects on the Tarn River (France)
Main Article Content
Abstract
A methodology to forecast river-pollution scenarios in case of accident was implemented for the Tarn River in the south of France. Field information about diffusion transport was sampled in different river discharge conditions by the use of two kinds of tracers: Rhodamine and Fluorescein. Numerical simulations were later implemented to reproduce additional scenarios. In this communication we would like to show the difficulties encountered in this study with the aim to improve in the selection of sample points for tracer campaigns and in the selection of numerical models for a realistic agreement with available information. Uncertainty in field information will influence the calibration phase in numerical models and by consequence the quality of the forecast.
