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.

Drought entails important effects on tree physiology, which may result in short- to long-term radial growth decreases. While the majority of studies have focused on annual drought-related variability of growth, relatively little is known about sustained growth decreases following drought years. We apply a statistical framework to identify climatic factors that induce abrupt growth decreases and...

Assessing incidence and trends of droughts floods can provide essential information for better water resource management, particularly in the context ongoing climate change. The present study has examined prevalence drought flood events Godavari basin, India, last four decades using Standardized Precipitation Evapotranspiration Index (SPEI) 3 months 9 months, their Mann–Kendall’s test Sen’s slo...

Drought is an extremely dangerous natural hazard that causes water crises, crop yield reduction, and ecosystem fires. Researchers have developed many drought indices based on ground-based climate data various remote sensing data. Ground-based are more accurate but limited in coverage; while the cover larger areas poor accuracy. Applying data-driven models to fuse multi-source for reproducing co...
