Abstract: Since hydrologic time series in general, and stream‐flow series, in particular, are dependent and not normally distributed, use of the classical autoregressive and moving average (ARMA) models to represent such series ...

Abstract: The estimation of return periods of hydrological events and the corresponding risks of failure of hydraulic structures that are associated with such events are important aspects in many water resources studies. For simple ...

Abstract: A mathematical formulation to estimate return periods and risks of failure of complex hydrologic events such as those arising from dependent floods and droughts have been examined in the first part of this paper. Specifically, ...

Abstract: The return period and risk of extreme droughts can be derived from hydrologic series of wet and dry years. If
