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...
The European Social Progress Index (EU-SPI) is a composite index launched by the Commission in 2016 to assess social progress. It constructed using non-economic indicators, and intended serve as tool for regional policies. This paper shows that 2020 release of robust multiple alternative designs, thus suitable policymaking. EU-SPI gross domestic product per capita (GDPpc) are positively correla...
UNLABELLED The aim of the study was to assess the usefulness of prognostic scales: ASA (American Society of Anesthesiologist), MPI (Meinheim Peritonitis Index), MOFS (the Multiple Organ Failure Score) and SPI (the Simple Prognostic Index) in the prognosis of the course of disease in patients operated on for peritonitis. MATERIAL AND METHODS The study was conducted in the Clinical Department o...
Drought is a natural phenomenon that causes lot of damages annually in various sectors, including agriculture and resources. The aim this study to evaluate the influence meteorological drought index on vegetation index. For purpose, standard precipitation (SPI) as calculated using data 28 stations located area Lorestane province, Iran, during years 1987–2017. Then, condition (VCI) computed norm...
Drought is a significant challenge to semiarid Mediterranean grasslands, Increasing the accuracy of monitoring allows improving conservation and management these vital ecosystems. Meteorological drought commonly monitored by Standard Precipitation Index (SPI) or Evapotranspiration (SPEI). On other hand, agriculture estimated Vegetation Health (VHI). This work aims optimise correlation between b...
Drought is an environmental disaster related to the extremes (on a drier side) in hydrometeorology. The precipitation amount modulates drought Nepalese river basins. It vital for efficient water resources management quantify and understand drought. This paper aims characterize droughts Nepal based on standard index (SPI) rainfall anomaly (RAI) using daily data assess their impacts annual crop y...
This research addresses issues relating to the implementation of software process improvement (SPI) initiatives. A number of advances have been made in the development of software process improvement (SPI) standards and models, e.g. Capability Maturity Model (CMM), more recently CMMI, and ISO's SPICE. However, these advances have not been matched by equal advances in the adoption of these stand...
Droughts affects on agriculture and water consumption management through LU/LC and water resources changes in western mountainous areas of Iran. The aim of this study was to investigate terrestrial and remote sensing drought indices and their effects on LU/LC and ground water level in Razan-Ghahavand watershed. Precipitation trend in two stations and water level trend in six piezometric well we...
The Standardized Precipitation Index (SPI) is the most common index for drought monitoring. Although the calculation of this index is usually done by using the gamma distribution fitting of precipitation data, studies have shown that for accurate monitoring of drought, the optimal distribution of precipitation in each month should be determined. On the other hand, in non-stationary time series,...
