A Mass-Conserving Spatiotemporal Graph ODE Model for Multi-Step Streamflow Forecasting in a Sparsely Gauged Semi-Arid Basin

Semi-arid loess basins in the middle Yellow River have rapid runoff responses, short hydrological memory, and sparse gauging networks, so pooled metrics across all stations can conceal forecast failures in low-flow tributaries and during dry periods. This study proposes DaSTGODE,...
