Abstract The Standardized Precipitation Index (SPI) is widely used as drought
meteorological index, to identify the duration and/or severity of a drought. The SPI is usually …

Local dry/wet conditions and extreme rainfall events are of great concern in regional water
resource and disaster risk management. Extensive studies have been carried out to …

Comparability analyses are performed to investigate similarities/differences of the standard
precipitation index (SPI) and the reconnaissance drought index (RDI), respectively, utilizing …

A reliable understanding of propagation from meteorological to hydrological drought is
necessary for accurate forecasting of hydrological droughts. Our current understanding of …

Droughts are an inevitable consequence of climate variability and are pervasive across
many regions. Their effects can vary on an extensive scale, depending on the type of …

Comparability analyses were carried out to investigate behavioural aspects of effective
drought index (EDI), standardized precipitation index (SPI), reconnaissance drought index …

Prediction of hydrological drought in the absence of hydrological records is of great
significance for water resources management and risk assessment. In this study, two …

Water resources management is a complex task. It requires accurate prediction of inflow to
reservoirs for the optimal management of surface resources, especially in arid and semi-arid …

Conventionally, drought analysis has been limited to single drought category. Utilization of
models incorporating multiple drought categories, can relax this limitation. A copula-based …

Under global climate change, drought has become one of the most serious natural hazards,
affecting the ecological environment and human life. Drought can be categorized as …
