| 英文摘要 | Conventional hydrological theory assumes that rainfall-runoff relationships recover to pre-drought conditions once a drought ends. However, persistent hydrological changes observed after the Australian Millennium Drought (1997-2009)-the most severe drought in recorded history-challenge this assumption. This prolonged lack of recovery has raised broader concerns, particularly for drought-prone regions worldwide. Drawing on the Millennium Drought as a representative case, this study examines the rainfall-runoff relationship in 155 catchments over a 13-year post-drought period to 2022. As of 2022, the rainfall-runoff relationship remains unrecovered in 24% of the catchments, which are primarily those with the most severe runoff deficits during the Drought. We examine the runoff deficit by separating it into surface and subsurface components and analyzing their relationships with environmental factors such as elevation, slope, valley bottom flatness, leaf area index, temperature, wind speed, and vapor pressure deficit, among others. The catchments with more surface runoff deficits than subsurface runoff deficits are mainly located in arid regions with high atmospheric evaporative demand, which may accelerate losses of surface runoff and soil moisture, leading to greater surface runoff deficits. The catchments with more subsurface runoff deficits are mainly located in high-elevation and vegetated regions, where subsurface runoff decreased substantially during the Drought due to groundwater table decline and vadose zone expansion. The results highlight the need to account for both surface and subsurface runoff when assessing runoff recovery from drought. |
