Le versant et le bassin versant. Quelques aperçus sur la formation des crues et la production du ruissellement

Abstract : This presentation aims at a state of the art on the current knowledge on flood flow generation in small to medium-sized, catchments (some 10 to a few 100km2), separating well-established concepts from present interrogations. Building on recent works, one shall address the role of topography, soil and land cover, as well as the role of rainfall distribution in space. More recently, some concerns have appeared from man-made effects (like tile drains or other artificial networks: roads, embankments, ditches) which will be briefly considered. Model limitations, as well as those of instrumentation, will also be addressed as limiting factors for our knowledge and therefore for the engineering answers that can be brought to flood forecasting and mitigation. Finally, one will consider whether there are different ways of working depending on normal or extreme conditions, and some related but open questions.
