Fractal geometry concepts are applied to analyse hard rock fracturing and t
he associated river network. The study area is located in the Ivory Coast (
region of Man). Analyses point out that fracture network is plane filling,
with D approximate to 2 at all scales. The river network displays a rupture
scale. This difference is interpreted in terms of geological constraints u
ndergone by the river network according to the scale. (C) 2001 Academie des
