Abstract: A general strategy for estimating the failure probability of the class of structural systems for which each deterministic structural analysis is expensive is proposed. The strategy is interactive, sequential, and iterative. ...

Abstract: A simple and methodical strategy is presented for estimating the parameters of a catchment. The method makes use of rainfall‐runoff records to construct response surfaces of the peak flow in terms of eight calibration ...

Abstract: The probabilistic‐based calibration strategy developed in this paper was briefly reviewed and applied to derive the optimum values of eight calibration parameters. Three optimum sets are obtained: estimations of peak flow, ...

Abstract: A new catchment calibration approach based on the fractional-factorial and central-composite designs (FFD-CCD) is presented in this paper. The proposed method requires fewer simulations (almost 75% less) than the approach ...
