Abstract: | This paper completes the series of three articles devoted to automated forecasting of flash floods 3, 5] and describes an
effective approach of forecast updating through post-processing operations, which can be useful only in conjunction with such
fast and efficient real-time re-calibration algorithms as SLS-based methods are. In particular, a proposed methodology is
aimed to reduce negative consequences of scarce or low-quality data that can corrupt optimized parameters and, therefore,
lower forecasting efficiency. A new modification of SLS-based optimization that supposes simultaneous re-calibration of the
model and correction of the model input by generating of ensemble noises (SLS-E) is presented. |
