Hydrology and Drought Analysis
Hydrology and Drought Analysis is a research topic within Global and Planetary Change. Science Explorer counts 26k research works in it since 1950. 23.0% of them reached the world's top 10% most cited for their field and year.
This cluster of papers focuses on the monitoring, assessment, and impacts of drought at a global scale. It covers various aspects such as the development of drought indices, the influence of global warming and climate change on drought severity and frequency, hydrological implications, remote sensing techniques for drought monitoring, and the use of evapotranspiration data. The research also delves into the challenges and future directions in drought assessment.
