| Zusammenfassung |
| This paper presents some analytical results and numerical illustrations on
the asymptotic properties of flood peak distributions obtained through
derived flood frequency approaches. It confirms and extends the results of
previous works: i.e. the shape of the flood peak distributions are
asymptotically controlled by the rainfall statistical properties, given
limited and reasonable assumptions concerning the rainfall-runoff process.
This result is partial so far: the impact of the rainfall spatial heterogeneity has not been
studied for instance. From a practical point of view, it provides a general framework for
analysis of the outcomes of previous works based on derived flood frequency
approaches and leads to some proposals for the estimation of very large
return-period flood quantiles. This paper, focussed on asymptotic
distribution properties, does not propose any new approach for the
extrapolation of flood frequency distribution to estimate intermediate return
period flood quantiles. Nevertheless, the large distance between frequent
flood peak values and the asymptotic values as well as the simulations
conducted in this paper help quantifying the ill condition of the problem of
flood frequency distribution extrapolation: it illustrates how large the
range of possibilities for the shapes of flood peak distributions is. |
