The study of the rainfall chronicles and its surroundings by standardized index (spi) randomness verification tests is great importance for management planning water resources. This work aims to variations regime over time determining precise years rupture in chronological series. considered data spread 4 decades (from 1980 inclusive 2019). These were used calculate Standard Pluviometric Precip...

In this paper, Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks–Climate Data Record (PERSIANN-CDR) is analyzed for the assessment of meteorological drought. The evaluation is conducted over China at 0.5 ̋ spatial resolution against a ground-based gridded China monthly Precipitation Analysis Product (CPAP) from 1983 to 2014 (32 years). The Standardized Pr...

Abstract In the tropical-humid region, wet farming crops (e.g., paddy) are a common agricultural commodity with high-water requirement. Usually planted in Asia monsoon region high precipitation rate, these divided into cropping season and dry season. During season, they particularly vulnerable to drought caused by decrease precipitation. This study used Indonesia as case is aimed at assessing r...

Drought is a natural disaster. Because a significant impact on the agricultural and economy sector, it affects the lives of local residents. With Using of the remote sensing, drought can be studied through its effects on plants and agriculture resulting in more accurate and effective results found for modeling drought. In this study, the efficiency of agricultural drought indicators for estimat...

Drought assessment and trend analysis of precipitation temperature time series are essential in the planning management water resources. Long-term historical records (monthly for 41 years, from 1980 to 2020) used investigate annual drought characteristics Somalia’s northern region. Six indices normal Standardized Precipitation Index (normal-SPI), log (log-SPI), using gamma distribution (Gamma-S...

Drought is a phenomenon that caused by several factors and can be divided into meteorological drought, agricultural hydrological socioeconomic drought. In this study, the characteristics of propagating from drought to (or hydrological) in Andong Dam basin Hapcheon located Nakdong River Korea were investigated. Standardized precipitation index (SPI), standardized soil moisture (SMI), runoff (SRI...

This paper focus on the drought monitoring and forecasting for semi-arid region based various machine learning models SPI index. Drought phenomena are crucial role in agriculture drinking purposes area. In this study, Standardized Precipitation Index (SPI) was used to predicted future upper Godavari River basin, India. We have selected ten input combinations of ML model were prediction three ti...
