This publication is the documented results of a workshop, Modeling and administration of rising Environmental concerns, held at Penn country college. Because historical floods by definition are large, their introduction in a flood frequency analysis can have a major impact on estimates of rare floods. These regionalization approaches aim to estimate different characteristics of the extreme hydrological phenomena of interest, make different assumptions and hypotheses concerning these hydrological phenomena, rely on various types of data, and often fall under completely different theories.

Maximum likelihood estimators based on partially censored data have been shown to be much more efficient and to provide a practical framework for incorporating imprecise and categorical data. Add a review and share your thoughts with other readers. hydrologiw

It is hoped that this document will contribute towards closing the gap between theory and practice, by narrowing the wide body of literature that is available, and by providing comprehensive propositions for regional frequency analysis approaches that meet the new challenges facing hydrologic engineers.

The basic hypothesis in the statistical modeling of historical information is that a certain perception water level exists and that during a given historical period preceding the period of gauging, hyrdologie exceedances of this level have been recorded, be it in newpapers, in people’s memory, or trough traces in the catchment such as sediment deposits or traces on trees.

Various statistical techniques for incorporating historical information into frequency analyses are discussed in this review paper. Local frequency analysis is commonly used for the estimation of frequenteille hydrological events at sites where an adequate amount of data is available. However, even with substantial uncertainty in the data, the use of historical information is a viable means to improve estimates of rare floods.
