Drought assessment is crucial for effective water resources management in a river basin. frequency has increased worldwide recent years due to global warming. In this paper, an attempt made assess the meteorological drought Punpun basin, India using two globally accepted indices namely, Standardized Precipitation Index (SPI) and Evapotranspiration (SPEI). The SPI SPEI at 1-, 3-, 6-, 9-, 12-mont...

State-of-the-art random forest (RF) models have been documented as versatile tools to solve regression and classification problems in hydrology. They can model stochastic time series by bagging different decision trees. This article introduces a new hybrid RF that increases the forecasting accuracy of RF-based models. The model, called GARF, is attained integrating genetic algorithm (GA) (RF), ...

Drought is a complex and highly destructive natural phenomenon that affects portions of the United States almost every year, and severe water deficiencies can often become catastrophic for agricultural production. Evapotranspiration (ET) by crops is an important component in the agricultural water budget; thus, it is advantageous to include ET in agricultural drought monitoring. The main object...

The goal of this study is to calculate meteorological drought using the Standard Precipitation Index (SPI) and Evapotranspiration (SPEI) for Al-Lith Khafji basins Kingdom Saudi Arabia (KSA) from 2001 2020. in situ (rain gauges, RGs) Integrated Multi-satellite Retrievals GPM (IMERG) data are used current study. monitored across AL-Lith watersheds. climate watershed like some extent. Still, due c...

Understanding the response of vegetation to drought is great significance biodiversity protection terrestrial ecosystem. Based on MOD13A2 NDVI, GOSIF, and SPEI data Yellow River Basin from 2001 2020, this paper used methods Theil–Sen median trend analysis, Mann–Kendall test, Pearson correlation analysis analyze whether change trends monitored by MODIS GOSIF are consistent their sensitivity mete...

At a hospital in Halifax, Nova Scotia, Canada, three strains of Legionella pneumophila were detectable based on plasmid content, while the isolates collected at another hospital in Halifax had no plasmids. Genomic DNA was digested with BssHII, SalI, and SpeI and subjected to pulsed-field gel electrophoresis (PFGE). We found no relationship between plasmid profile and PFGE pattern.
