Controls on drought propagation in drylands
Drought propagation in dryland environments is often conceptualised as a sequential transfer of meteorological deficits into soil moisture, streamflow, and groundwater drought with the propagation rate controlled by catchment and aquifer properties.George Blake +4 more

Propagation from meteorological drought to hydrological drought on the Loess Plateau, China
2020<p>Drought is the most recurrent and destructive hazard in arid and semi-arid regions, and will only become more complex under climate change. It is vital to characterize the various types of drought, to investigate the potential factors affecting different types of drought, and to assess the relationship between drought types ...

Droughts significantly impact terrestrial vegetation ecosystems. Understanding the mechanisms by which drought affects ecosystems under different hydrogeological conditions is crucial for ecosystem protection. The aim of this study was to investigate the characteristics and mechanisms of propagation from meteorological drought (MD) to agricultural ...

Meteorological droughts often propagate to agricultural (and other) droughts, both spatially and temporally. The present study proposes a novel complex networks-based cascading spatial drought network to examine the spatial propagation of meteorological droughts in a region to agricultural droughts in other regions.

Propagation and spatial distribution of drought in a groundwater catchment
Journal of Hydrology, 2006Natural droughts are usually caused by a period of lower than average precipitation. The resulting shortage in precipitation propagates through the hydrological system causing drought in the different segments of the hydrological system (unsaturated zone, saturated groundwater, surface water).

Propagation of meteorological drought to groundwater in Europe
Groundwater is a vital natural resource, providing the primary source of freshwater for billions of people across the globe and supporting a diverse range of groundwater-dependent ecosystems. Groundwater drought, which is defined as a prolonged period of below-normal groundwater levels, threatens our reliance on this important resource.Aimee Lenthall, Shams Rahman, Fai Fung
