In this study, to improve the efficiency of the original Palmer Drought Severity Index (PDSI_original), we coupled the Soil and Water Assessment tool (SWAT) and PDSI_original to construct a drought index called PDSI_SWAT. The constructed PDSI_SWAT is applied in the Wei River Basin (WRB) of China during 1960–2012. The comparison of the PDSI_SWAT with four other commonly used drought indices reve...

Drought is one of the least understood and complex natural hazards often characterized by a significant decrease in water availability for prolonged period. It can be manifested or more forms as meteorological, agricultural, hydrological, and/or socio-economic drought. The overarching objective this study to demonstrate characterize different droughts assess multidimensional nature drought Abba...

Volta River Basin, West Africa Hydrological droughts have a wide range of impacts on societies and economic sectors such as agriculture energy production. Analysis hydrological helps better plan manage water resources under global change. This study analyses the spatial temporal variability drought occurrence (duration severity) in basin during 1979–2013. We used Variable Infiltration Capacity ...

Drought is one of the most complex and threatening disasters, defined as a period drier-than-normal conditions which results in water-related problems. In addition to climate variation, human activities can cause or intensify drought through groundwater overextraction, unsupervised expansion agricultural lands, etc. One prime example such has been observed Zayandehrud River basin central Iran. ...

Soil moisture (SM) is an important parameter in all environments because it affects the relationship between land surface and atmospheric processes. Therefore, finding products that can accurately measure SM critical to improving drought management. The objective of this study was investigate accuracy satellite data from produced by China Meteorological Administration Land Data Assimilation Sys...

This paper describes the research project on the development of an ontology-based semantic search system for drought management of the Chi River Basin (CRB), Thailand. The research methods included Ontology Development 101 by adopting Noy & McGuinness (2001) and Ontology-based Application Management framework by adopting Buranarach et al. (2012). Seventeen experts including ten experts in the a...

In this study, a framework to project the potential future climate change impacts on extreme hydrological drought events in the Weihe River basin in North China is presented. This framework includes a largescale hydrological model driven by climate outputs from a regional climate model for historical streamflow simulations and future streamflow projections, and models for univariate drought ass...

The interaction of feeding by a grass bug, Ir"bisia pacifica (Uhler), and drought stress on growth of Great Basin wildrye, Leymus cinereus (Scrih. & Merr.) Love, and intermediate wheatgrass, Thinopyrum intermedium (Host) Barkw. & D. R. Dewey, was studied in the greenhouse. At peak production, control plants of Great Basin wildrye had more than twice as much green leaf area per tiller than bug-i...
