Headwater streams represent a substantial proportion of river systems and many of them have intermittent flows due to their upstream position in the network. These intermittent rivers and ephemeral streams have recently seen a marked increase in interest, especially to assess the impact of drying on aquatic ecosystems. The objective of this paper i...
The world is witnessing major environmental changes, which are a consequence of increasing impacts and pressure on the natural system. Hydrological processes at the catchment scale are sensitive to these changes, and the resulting effect is an increase in the frequency of extreme events such as flooding and droughts, which cause serious damages to ...

En Afrique tropicale et dans le bassin béninois de la Volta, de nombreuses études montrent que les eaux de surface sont très tributaires de la variabilité climatique. L'instabilité pluviomérique des années 1960 à nos jours a contribué à une modification des régimes hydrologiques dans le bassin de la Pendjari. Le but de cette étude est la modélisati...
Cette étude évalue l'impact de la densité spatiale du réseau hydrométrique sur certains calculs hydrologiques, en situation de bassin versant non jaugé. Nous abordons la simulation de chroniques de débit journalier, l'estimation du module, de débits de crues décennale et centennale et de certaines caractéristiques de débit d'étiage.Dans ce contexte...
