Abstract
Effective reservoir operation is critical for achieving multiple water management objectives, while also representing a major human intervention in hydrologic processes. Yet for most reservoirs, the lack of complete daily operation records and realistic accurate operation rules constrains their representation in large-scale hydrological models. To address this gap, we present GDROM v2, a nationwide dataset covering daily operation variable time series and derived operation rules for 2,017 large reservoirs across the Contiguous United States (CONUS), building upon the original GDROM (Li et al., 2023. Hydroshare. https://doi.org/10.4211/hs.63add4d5826a4b21a6546c571bdece10) of 452 reservoirs.
The dataset includes:
1. Time series of daily inflow, release, and storage (collected, cleaned, and normalized)
2. Operation rules for each reservoir expressed as “if–then–else” statements
3. Python scripts and instructions for using and training GDROMs
GDROM v2 offers the largest open collection of reservoir operation variable time series and realistic operation rules across the CONUS, providing a useful resource for hydrological modeling and water management studies.
