Analyse morphologique de talwegs et comportement scalant : applications des dimensions non-entières à la géographie physique
1999
Morphological talweg analysis and scaling behaviour: applying non-integer dimension to physical geography. -- The organisation of the talweg network is fundamental to the erosion system on the silty loamy plateaux of north-western France. The morphology of the Pays de Caux is a good example of successive runoff concentration caused by the nesting of small dry valleys. These are inherited from a periglacial climate and their general direction is governed by tectonics. However the detailed pattern of these forms remains complex and without obvious explanation. Non-integer dimensions may offer a ceratin logic to this relatively chaotic pattern. This paper has therefore sought to demonstrate th…
La formalisation fractale des tissus urbains
1998
The article concerns the fractal approach as it can bring new results making more understandable the morphology of agglomerate urban patterns. A new paradigm is developed, in order to improve the study of urban organizations according to optimization criteria. Specific fractal and multifractal methods are explicitated and applied to the knowledge of some big metropolitan areas and towns in Franche-Comté (France).
