Open AccessImproving the probabilistic drought prediction with soil moisture information under the ensemble streamflow prediction framework
Reliable drought prediction should be preceded to prevent damage from potential droughts. In this context, this study developed a hydrological drought prediction method, namely ensemble drought prediction (EDP...

Adaptive Reservoir Management by Reforming the Zone-based Hedging Rules against Multi-year Droughts
In this study, the zone-based hedging rule, which is the main operating policy adopted from multipurpose reservoirs in Korea is adjusted to reflect the multi-year droughts caused by climate change. Annual synt...

How Does the Coupling of Real-World Policies with Optimization Models Expand the Practicality of Solutions in Reservoir Operation Problems?
This study first compares how different formulations of a reservoir operation problem with conflicting objectives affect the quality of the generated solution set. Six models were developed for comparative ana...

Valuation of Water Resources Infrastructure Planning from Climate Change Adaptation Perspective using Real Option Analysis
For adaptation to the changing climate, planning of new water infrastructures should be carefully evaluated by either “robust” or “adaptive” decision making methods. For this purpose, a new economic feasibilit...

Time-Varying Discrete Hedging Rules for Drought Contingency Plan Considering Long-Range Dependency in Streamflow
This study proposed a simple and efficient method for develo** time-varying discrete hedging rules. The novelty of the proposed methodology is that long-range streamflow traces are inserted into the sequent ...

Selecting climate change scenarios for regional hydrologic impact studies based on climate extremes indices
When selecting a subset of climate change scenarios (GCM models), the priority is to ensure that the subset reflects the comprehensive range of possible model results for all variables concerned. Though many s...

Application of distribution-free nonstationary regional frequency analysis based on L-moments
Regional frequency analysis (RFA) based on L-moments is widely used in the analysis of hydrological process. However, L-moments are defined by order statistics from a stationary distribution and thus theoretic...

Application of real option analysis for planning under climate change uncertainty: a case study for evaluation of flood mitigation plans in Korea
With concerns regarding global climate change increasing, recent studies on adapting to nonstationary climate change recommended a different planning strategy that could spread risks. Uncertainty in global cli...

Scaled ridge estimator and its application to multimodel ensemble approaches for climate prediction
We propose a new regularized estimator called the scaled ridge estimator. The scaled ridge estimator is a modified version of the ridge estimator devised to reduce the bias of the ridge estimator by multiplying a...

Diode-pumped solid-state laser for bonding orthodontic brackets: effect of light intensity and light-curing time
This study evaluated the shear bond strength (SBS) of orthodontic brackets bonded to teeth using a diode-pumped solid state (DPSS) laser of 473 nm with various light intensity and light-curing settings. For th...
