Lags in hydrologic recovery following an extreme drought: Assessing the roles of climate and catchment characteristics

Editor’s Highlight—

 

Hydrological drought recovery is a very new field of research, and it is also rarely quantified. This study presents an analysis of recovery after the Millennium Drought in southeast Australia using data from 130 catchments. The authors demonstrate how hydrological drought recovery is related to catchment controls and climate factors. The results show that the amount of precipitation between the end of the meteorological drought and the end of the hydrological drought was the main driver of the recovery duration, followed by catchment characteristics (mainly valley flatness) and evaporation between the end of the meteorological drought and the end of the hydrological drought. This study contributes to our empirical understanding of drought propagation through catchments, particularly for the case of extended drought.
