Development of a Hydrological Drought Index Considering Water Availability

A Drought Indicator based on Ecosystem Responses to Water Availability: The Normalized Ecosystem Drought Index

Drought is one of the most destructive natural disasters causing serious damages to human society, and studies have projected more severe and widespread droughts in the coming decades associated with the warming climate. Although several drought indices have been developed for drought monitoring, most of them were based on large scale environmental conditions rather than ecosystem transitional ...

Hydrological drought analysis using SDI index in Halilrud basin of Iran

Hydrological drought analysis using SDI index in Halilrud basin of Iran Abstract Nowadays, drought is considered as damaging environmental phenomenon which affects natural resources and social communities. Therefore it will be an important issues that magnitude and effects of these phenomena to be considered. To do this we used L-moment method for regional homogeneity testing. The Streamflow Dr...

Modeling and Analysis Considering water availability and wastewater resources in the development of algal bio-oil

This study aims to quantify water appropriation and the potential production of algal bio-oil using freshwater and municipal wastewater effluent (MWW) as an alternative water resource. The county-level analysis focuses on open-pond algae cultivation systems located in 17 states in the southern United States. Several scenarios were developed to examine the water availability for algae bio-oil pr...

Assessing water resource system vulnerability to unprecedented hydrological drought using copulas to characterize drought duration and deficit

Global climate models suggest an increase in evapotranspiration, changing storm tracks, and moisture delivery in many parts of the world, which are likely to cause more prolonged and severe drought, yet the weakness of climate models in modeling persistence of hydroclimatic variables and the uncertainties associated with regional climate projections mean that impact assessments based on climate...
