An autoencoder-based snow drought index. [PDF]

Sci Rep, 2023
AbstractIn several regions across the globe, snow has a significant impact on hydrology. The amounts of water that infiltrate the ground and flow as runoff are driven by the melting of snow. Therefore, it is crucial to study the magnitude and effect of snowmelt.

Comparing surface water supply index and streamflow drought index for hydrological drought analysis in Ethiopia. [PDF]

Heliyon, 2022
Recently, floods and drought have become common natural hydroclimatic hazards in several countries. Consequently, the identification of an appropriate drought index is now a challenging task for researchers. It is obvious that there is not a single best drought index; rather a comparison of indices will give a relative option.

A support vector machine based drought index for regional drought analysis. [PDF]

Sci Rep
AbstractThe increased global warming has increased the likelihood of recurrent drought hazards. Potential links between the frequency of extreme weather events and global warming have been suggested by earlier research. The spatial variability of meteorological factors over short distances can cause distortions in conclusions or limit the scope of ...

Tools for Drought Identification and Assessment: A Review

Journal of Engineering, 2023
Drought is a natural phenomenon in many arid, semi-arid, or wet regions. This showed that no region worldwide is excluded from the occurrence of drought. Extreme droughts were caused by global weather warming and climate change.
