abstract drought is one the most complicated and unknown natural disasters and rainfed agriculture is often the first sector to be affected by drought. in this research, we consider the drought monitoring from both meteorological and agricultural points of view. we have selected standardized precipitation index (spi) among the meteorological indices, with a one month time scale for the synoptic...

an important and fundamental issue in iran is to utilize water and to avoid wasting it. therefore, climate change can be considered as an effective factor on water resources. the most tangible climate change phenomenon is drought which is much important to be identified. in this study, the effect of climate changes on flow rate in bashar river, shahmokhtar station of yasouj city was evaluated u...

Satellite-based precipitation products can be a better alternative of rain gauges for hydro-meteorological studies in data-poor regions. This study aimed to evaluate how regional and seasonal drought patterns had changed the Ganga–Brahmaputra Basin between 1983 2020 with PERSIANN-CDR data. The spatial pattern winter drought, monsoon Standardized Precipitation Index (SPI) calculated different ti...

Drought is a major environmental disaster in many parts of the world. Knowledge about the timing, severity and extentof drought can aid planning and decision-making. Drought indices derived from in-situ meteorological data have coarsespatial and temporal resolutions, thus, obtaining a real-time drought condition over a large area is difficult. This studyused advanced very high resolution radiom...

Kabul River Basin is one of the most significant river basins in Afghanistan from a socio-economic perspective. Since country located an arid climate zone with drastically varying climatic behavior, effective assessment meteorological drought very essential to managing limited availability water resources. For this endeavor, outputs three general circulation models under two representative conc...
