Location of the Real Collobrier experimental research basin and of the Rimbaud and Vaubarnier <br />sub-basins. <br /> <br />TABLE I <br /> <br />Summary of the main characteristics of the Rimbaud basin before the fire (1967-1989) <br /> <br />recorded during August. Thus the 1990 hydrological year can be considered <br />to be totally post-fire. <br />The data were continuously recorded during this period and only the flows <br />from 5 to 25 October were missed. In the study, the monthly total flow of <br />October was reconstituted using the next flow recorder station located in the <br />Rimbaud stream. For the precipitation data we used the values measured by <br />the pluviograph located inside the basin. Complementary data from the Real <br />Collobrier meterological station nearby were also used. <br /> <br />Surface area <br />Distance to the sea <br />Elevation range <br />Vegetation <br /> <br />l40ha <br />ISkm <br />470-670 m <br />Totally forested by maquis and degraded forest of cork <br />trees and chestnuts <br />Slightly altered gneiss <br />II64mm <br />201s-1 <br />13.7mls-1 <br />6m)s-1 <br />Marginal <br /> <br />Geology <br />Annual mean precipitation <br />Mean discharge <br />Maximal discharge <br />10 year return period f1.ow <br />Human influence <br /> <br />
