Abstract
This HydroShare Resorce provides the data, code, and results for the manuscript under review by JAMES. The abstract of the manuscript is as follows: Accurately representing daily reservoir operations in large-scale hydrological and water resource modeling remains challenging due to both the complex and vague nature of real-world operations and very limited availability of operation records for many reservoirs worldwide. To address this gap, this study introduces MODROM (MOdular Data-driven Reservoir Operation Model), a parsimonious reservoir parameterization scheme that conceptualizes reservoir operations through simple operation modules and their seasonal transitions. These operation modules are designed to be simple and parsimonious for easier generalizing from data-rich to data-scarce reservoirs. MODROM is calibrated using high-quality long-term operation records from more than 400 data-rich reservoirs across the Contiguous United States (CONUS), and a Random Forest model is developed to provide calibrated parameters for data-scarce reservoirs based on a suite of static reservoir characteristics. Results demonstrate MODROM’s strong and robust performance when calibrating using all available data for each reservoir, though the performance generally declines for reservoirs with larger regulation capacity. The generalization performance is strong under favorable sampling conditions but is affected by sampling uncertainty due to the limited reservoir dataset. Benchmarking against existing models shows that MODROM offers distinct advantages in generalizing parameters to data-scarce reservoirs using readily available static reservoir characteristics, with the potential for global-scale application.
