Value of Seasonal Flow Forecasts in Bayesian Stochastic Programming
Publisher: American Society of Civil Engineers
Abstract: This paper presents a Bayesian Stochastic Dynamic Programming (BSDP) model to investigate the value of seasonal flow forecasts in hydropower generation. The proposed BSDP framework generates monthly operating policies for ...
Combining Rainfall-Runoff Model Outputs for Improving Ensemble Streamflow Prediction
Publisher: American Society of Civil Engineers
Abstract: This study reviewed various combining methods that have been commonly used in economic forecasting, and examined their applicability in hydrologic forecasting. The following combining methods were investigated: The simple ...
Climate Change Impact Assessment Using K-Nearest Neighbor Weather Generator: Case Study of the Nakdong River Basin in Korea
Publisher: American Society of Civil Engineers
Abstract: This study presents a methodology for assessing impacts of climate change in regional-scale hydrology using the K-nearest neighbor weather generator (WG) model in combination with the outputs of global circulation models ...
Optimal Drought Management Using Sampling Stochastic Dynamic Programming with a Hedging Rule
Publisher: American Society of Civil Engineers
Abstract: This study develops procedures that calculate optimal water release curtailments during droughts using a future value function derived with a sampling stochastic dynamic programming model. Triggers that switch between a ...
Improving the Robustness of Reservoir Operations with Stochastic Dynamic Programming
Publisher: ASCE
Abstract: Reservoir operations should consider both adaptiveness and robustness to deal with two of the main characteristics of climate change: nonstationarity and deep uncertainty. In particular, robust operational strategies are ...
Optimizing Operational Policies of a Korean Multireservoir System Using Sampling Stochastic Dynamic Programming with Ensemble Streamflow Prediction
Publisher: American Society of Civil Engineers
Abstract: This study presents state-of-the-art optimization techniques for enhancing reservoir operations which use sampling stochastic dynamic programming (SSDP) with ensemble streamflow prediction (ESP). SSDP used with historical ...
