Abstract: A topic of paramount importance, within the formulation of any integrated water resources management program, is that of flood frequency analysis. Flood frequency analysis downstream of a junction of two rivers, when flood information is available upstream of the confluence, has been achieved so far only for the cases of complete dependence or complete independence. In the paper, a model for partial dependence is explored through the use of probabilistic model based on one type bivariate extreme value distribution (Logistic model). The model is constructed through the convolution of the two random variables, namely the extreme flows upstream of the confluence, and constitutes an approximation of the actual physical process. A good agreement has been observed between the model and the actual flood data downstream of the junction of the two rivers. An example of application of the proposed methodology is contained in the paper.
