Analyzing the Spatial and Temporal Dynamics of Rainfall and Drought in The Vall River Basin, South Africa	2025	16	.pdf	application/pdf	6585	263	53	The years most affected by hydrological drought from 1983 to 2023 in the lower Vaal, middle Vaal, and Upper Vaal River basins, as indicated by SPEI/SPI-12 and SPEI/SPI-24, were 1983-1985, 1992, 1995, 2003, 2004, 2007, and 2012-2016. The study main objectives were to utilize SPI and SPEI drought indices to evaluate drought patterns from 1983 – 2023, produce rainfall maps for the Vaal River basin and adjacent provinces, identifying evapotranspiration patterns and assess the extent of drought effects in the study area.	cache/azojete-1175.pdf	txt/azojete-1175.txt
