G-grey-extrapolation combined modela grey-extrapolation combined model with self-review-correction mechanism for robust river water-level forecasting under small-sample hydrological conditions

Floods and droughts threaten ecological security and sustainable development, so reliable river water-level forecasting is essential for early warning systems. However, existing models are often undermined by small-sample scenarios, data anomalies, and missing data. This study proposes the G-GECM (grey-extrapolation co...
