摘要：

The discharge-duration-frequency approach, called QdF, makes it possible to describe the flood hydrological regime of a catchment from a statistical point of view. Equivalent to intensity-duration-frequency curves for rain, QdF curves represent discharge distributions for different d durations. The multiduration continuous model, presented in this paper, aims to describe these distributions continuously, as a function of d. When the statistical law is the exponential law, this model contains only four parameters, due to observed scale invariance properties. Consequently, these four parameters characterize the flood hydrological regime of the studied catchment. ((C) Academie des sciences / Elsevier, Paris.).
