| 英文摘要 | Lumped hydrological models are widely used for hydrological simulations in basins due to their simple data requirement, ease of operation and reasonable performance. However, most lumped models are limited by their structure, making them unable to account for the impact of basin heterogeneity on runoff and soil moisture dynamics. To overcome these limitations, we proposed an extension approach that incorporates the Pareto distribution of soil water storage capacity to enhance lumped hydrological models, providing a statistical spatial description of runoff and soil moisture variability. This approach was applied to a structurally simple lumped time-variant gain model and tested over four basins in China to reproduce daily runoff and soil moisture dynamics. Additionally, numerical experiments were conducted to validate the effectiveness of this extension in terms of runoff mechanisms. The findings reveal that, compared with the original time-variant gain model, the enhanced model better captures hydrological dynamics, with a 7.9% improvement in total runoff accuracy, 11.2% in low-flow metrics and 30.8% in soil moisture simulation. This demonstrated that it is possible to enhance the ability of lumped models to respond to the basin spatial heterogeneity without significantly increasing the complexity, providing valuable insights for the further development of such models. |
