In a field experiment to investigate potential impacts of climatic change, a small area of flush wetland in Wales was subjected to three successive years of simulated summer drought/rewetting (autumn...
Soil moisture gradients and controls on a southern Appalachian hillslope from drought through recharge
Soil moisture watersheds
2009/5/27
Soil moisture gradients along hillslopes in humid watersheds, although indicated by vegetation gradients and by studies using models, have been difficult to confirm empirically. While soil properties...
Hydrological response to different time scales of climatological drought：an evaluation of the Standardized Precipitation Index in a mountainous Mediterranean basin
Standardized Precipitation Index drought conditions
2009/5/18
At present, the Standardized Precipitation Index (SPI) is the most widely used drought index to provide good estimations about the intensity, magnitude and spatial extent of droughts. The main advanta...
