Peters, E., 2003. Propagation of drought through groundwater systems Illustrated in the Pang (UK) and Upper-Guadiana (ES) catchments. Ph.D. thesis, Wageningen University, The Netherlands. 203 pp. The transformation of droughts as a result of the propagation through groundwater systems is examined by comparing droughts in time series of groundwater recharge, levels and discharge. The groundwater...

introduction: drought is a creeping natural phenomenon, which can occur in any region. such phenomenon not only affects the region subjected to drought, but its adverse effects can also be extended to other adjacent regions. this phenomenon mainly starts with water deficiency (say less than long- term mean of variable under study such as rainfall, streamflow, groundwater level or soil moisture)...

Efficient nitrogen (N) nutrition has the potential to alleviate drought stress in crops by maintaining metabolic activities even at low tissue water potential. This study was aimed to understand the potential of N to minimize the effects of drought stress applied/occur during tillering (Feekes stage 2) and jointing (Feekes stage 6) growth stages of wheat by observing the regulations and limitat...

Globally documented widespread drought-induced forest mortality has important ramifications for plant community structure, ecosystem function, and the ecosystem services provided by forests. Yet the characteristics of drought seasonality, severity, and duration that trigger mortality events have received little attention despite evidence of changing precipitation regimes, shifting snow melt tim...

An understanding of drought occurrences and their characteristics such as intensity, duration, frequency, and areal coverage, and their variations on different spatial scales, is crucial to plan for droughts in different regions and in different sized areas. This study investigated the variations of spatio-temporal characteristics of droughts under selected spatial scales: National (Contiguous ...

The severity of recent droughts in semiarid regions is increasingly attributed to anthropogenic climate change, but it is unclear whether these moisture anomalies exceed those of the past and how past variability compares to future projections. On the Mongolian Plateau, a recent decade-long drought that exceeded the variability in the instrumental record was associated with economic, social, an...

proportionality of wheat cultivars growth patterns to the area’s agro climatic condition will improve crop production. the objective of this study was identifying the phenology of a wide range of wheat varieties in iran, as well as evaluating the relationship between phenology and drought stress tolerance under late season drought stress. in this experiment, 36 wheat genotypes were studied unde...
