Influence of weak trends on exceedance probability

Published

Journal Article

Studying the hypothetical case of a trend superimposed on a random stationary variable, we highlight the strong influence of possible nonstationarities on exceedance probability. After a general outline, the subject is analytically developed using the Gumbel distribution, emphasizing the quick increase of the exceedance probability over time in the presence of weak rising trends, and its sensitive underestimation where the non-stationarity goes unnoticed or is considered negligible. Finally the work is applied to hydrological series of rainfall and river flow. © Springer-Verlag 1998.
