This site therefore seemed especially relevant to the process of identifying and
understanding what factors lead to successful warning provision, despite uncertainty,
short lead-times and multiple scales.
The sample of individuals selected for questioning was based on the aforemen-
tioned need to consider the warning process in all its dimensions. Specifi cally,
this meant identifying all the actors concretely involved in the process, offi cially or
otherwise, from weather forecasters to local residents.
The sample thus encompasses all the actors seen in practice to be involved in
hydro-meteorological warnings for the Vidourle watershed. It is characterised by
the heterogeneity of the actors and the range of spatial scales (town, watershed,
departmental, regional and national levels) and temporal scales (from 10 min to a
full week) involved.
