Estimation of predictive hydrologic uncertainty using the quantile regression and UNEEC methods and their comparison on contrasting catchments

Dogulu, N. (author), Lopez Lopez, P. (author), Solomatine, D.P. (author), Weerts, A.H. (author), Shrestha, D.L. (author)

In operational hydrology, estimation of the predictive uncertainty of hydrological models used for flood modelling is essential for risk-based decision making for flood warning and emergency management. In the literature, there exists a variety of methods analysing and predicting uncertainty. However, studies devoted to comparing the performance...

Alternative configurations of quantile regression for estimating predictive uncertainty in water level forecasts for the upper Severn River: A comparison

Lopez Lopez, P. (author), Verkade, J.S. (author), Weerts, A.H. (author), Solomatine, D.P. (author)

The present study comprises an intercomparison of different configurations of a statistical post-processor that is used to estimate predictive hydrological uncertainty. It builds on earlier work by Weerts, Winsemius and Verkade (2011; hereafter referred to as WWV2011), who used the quantile regression technique to estimate predictive...

Advancing data assimilation in operational hydrologic forecasting: Progresses, challenges, and emerging opportunities

Liu, Y. (author), Weerts, A.H. (author), Clark, M. (author), Hendricks Franssen, H.J. (author), Kumar, S. (author), Moradkhani, H. (author), Seo, D.J. (author), Schwanenberg, D. (author), Smith, P.

Data assimilation (DA) holds considerable potential for improving hydrologic predictions as demonstrated in numerous research studies. However, advances in hydrologic DA research have not been adequately or timely implemented in operational forecast systems to improve the skill of forecasts for better informed real-world decision making. This is...

Estimation of predictive hydrological uncertainty using quantile regression: Examples from the National Flood Forecasting System (England and Wales)

Weerts, A.H. (author), Winsemius, H.C. (author), Verkade, J.S. (author)

In this paper, a technique is presented for assessing the predictive uncertainty of rainfall-runoff and hydraulic forecasts. The technique conditions forecast uncertainty on the forecasted value itself, based on retrospective Quantile Regression of hindcasted water level forecasts and forecast errors. To test the robustness of the method, a...

Uncertainty assessment via Bayesian revision of ensemble streamflow predictions in the operational river Rhine forecasting system

Reggiani, P. (author), Renner, M. (author), Weerts, A.H. (author), Van Gelder, P.A.H.J.M. (author)

Ensemble streamflow forecasts obtained by using hydrological models with ensemble weather products are becoming more frequent in operational flow forecasting. The uncertainty of the ensemble forecast needs to be assessed for these products to become useful in forecasting operations. A comprehensive framework for Bayesian revision has been...
