EAVES-KSA: elevation-area-volume curves for 526 Saudi Arabian reservoirs

Elevation-area-volume (EAV) curves for the 526 cataloged reservoirs of Saudi Arabia, reconstructed from SRTM topography: 322 curves fitted directly from pre-impoundment SRTM flood fills and 204 assigned by a region-trained regionalization. The release contains the per-dam power-law coefficients (V = c·A^b), per-dam hypsometries at 0.5 m bins, quality grades and uncertainty flags, a three-term volume uncertainty band, the full validation suite (leave-one-out cross-validation, DEM-error Monte Carlo, sensitivity sweep), the Baish design table and 2025 sonar survey, a column-level data dictionary, the figure panels (PNG), and a summary report (report.md). Code: https://github.com/hyex-research/EAVES (Apache-2.0). The dataset accompanies the Scientific Data Data Descriptor "Elevation-area-volume curves for 526 Saudi Arabian reservoirs from SRTM topography and regionalization".
