Stochastic finite element and risk analysis in water resources management

There are a lot of uncertainty factors in an water resource project as: geological, hydrodynamic, numerical, technical, economic, financial, social, environmental, etc. This paper presents three uncertainty factors, which are described (in the view of stochastic fluid flow) and principally quantified analyzing geostatistical, finite element and numerical models. Taking into account the risk analysis is composed by many different models, there are only presented its principal steps, in order to asses a water project using Net Present Value criterion. Finally are given the conclusions.
