The use of geographic information systems (GISs) and remote sensing to facilitate the estimation of runoff from watershed and agricultural fields has gained increasing attention in recent years. This is mainly due to the fact that rainfall-runoff models include both spatial and geomorphologic variations. The US Department of Agriculture, Natural Resources Conservation Service Curve Number (USDA...
introduction: snowmelt runoff plays an important role in providing water and agricultural resources, especially in mountainous areas. there are different methods to simulate the process of snowmelt. inter alia, degree-day model, based on temperature-index is more cited. snowmelt runoff model is a conceptual hydrological model to simulate and predict the daily flow of rivers in the mountainous b...
Determining the actual evapotranspiration value and analyzing its temporal trend is essential for optimal water resources management in a basin. In the present paper, the actual evapotranspiration time series is simulated and its trend is analyzed according to the trend of climatic variables and land use in the Ajichi basin during the period of 2015-1987. The comprehensive SWAT model was set up...
In the context of global climate change, many studies have focused on interannual vegetation variation trends and their response to precipitation temperature, but ignored effects seasonal variability. This study explored relationship between normalized difference index (NDVI) elements in Wuliangsu Lake Basin area from 1990 2020, quantified impacts human activities dynamics. We used Landsat seri...
The Ganga basin constitutes a major part of northern India and is a part of the Ganga–Brahmputra–Meghna basin. The basin has a population of over 460 million. With growing population, urbanization and industrialization, the climatic conditions are found to change significantly, which has a direct impact on agricultural productivity. The hydrological regime of the basin is interrelated with the ...

purpose a metabolic abnormality such as obesity is a major obstacle in the maintenance of the human health system and causes various chronic diseases including type 2 diabetes, hypertension, cardiovascular diseases, as well as various cancers. this study was designed to summarize the recent scientific knowledge regarding the anti-obesity role of curcumin (diferuloylmethane), which is isolated f...
Study of land use/cover changes is widely used in environmental planning. During the last decade, growing increase of aridity in Uromiyah Basin has become a major regional and even national problem. The purpose of this study is to reveal the changes in land use/cover in the southern and southeastern parts of the basin with using 2 images for month of July of 2000 to 2017. Landsat TM and OLI dat...
Drought is an inevitable condition with negative impacts in the agricultural and climatic sectors, especially developing countries. This study attempts to examine spatial temporal characteristics of drought its trends Koshi River Basin (KRB) Nepal, using standardized precipitation evapotranspiration index (SPEI) over period from 1987 2017. The Mann-Kendall test was used explore SPEI values. ill...
