Drought monitoring using deciles index standardized precipitation index and effective Drought index in tehran province iran

A new method for evaluation and comprehensive drought Monitoring in the Urmia Lake Basin using a Synthesized Drought Index (SDI)

Drought is a complex phenomenon caused by the breaking of water balance and it has always an impact on agricultural, ecological and socio-economic spheres. Although the drought indices deriving from remote sensing data have been used to monitor meteorological or agricultural drought, there are no indices that can suitably reflect the comprehensive information of drought from meteorological to a...

Multivariate Standardized Drought Index: A parametric multi-index model

Defining droughts based on a single variable/index (e.g., precipitation, soil moisture, or runoff) may not be sufficient for reliable risk assessment and decision-making. In this paper, a multivariate, multiindex droughtmodeling approach is proposed using the concept of copulas. The proposed model, named Multivariate Standardized Drought Index (MSDI), probabilist ically combines the Standardize...

A data fusion-based drought index

Drought and water stress monitoring plays an important role in the management of water resources, especially during periods of extreme climate conditions. Here, a data fusion-based drought index (DFDI) has been developed and analyzed for three different locations of varying land use and climate regimes in Australia. The proposed index comprehensively considers all types of drought through a sel...

Accurate Computation of a Streamflow Drought Index

In this study we investigated an approach to the calculation of a Standardized Streamflow Index (SSI) that allows accurate spatial and temporal comparison of the hydrological conditions of a stream or set of streams. For this purpose the capability of six three-parameter distributions (lognormal, Pearson type III, log-logistic, General Extreme Value, Generalized Pareto and Weibull) and two diff...
