The quantity and variability of soil organic carbon (SOC) is one of the most important indices to determine the effect of land use changes on the soil quality. Regarding long-term changes from rangeland to dry farming in the Roin area of North Khorasan, the objectives of this study were to investigate the effect of long-term land use changes on the SOC in different slope faces and use SOC as an...

In recent decades, land use changes have been one of the most important environmental issues worldwide. This study was carried out to investigate and analyse land use changes in dust sources of south and south-east Ahwaz and surrounding lands using remote sensing technique. Firstly, based on the standard precipitation index (SPI), the years 1986, 2002 and 2016 were selected as years with near n...

Studying the morphology of the rivers and identifying the causes of these changes are widely useful in determining the evolution of rivers and planning the maintenance of the river system. The Karun River, between Bandar-e-Khoramshahr and the constant flow of water in the country, plays an important role in the country's water cycle. Due to the morphological changes of this river that have disr...

Aims and Background: The present study purpose to investigate and predict the changes of metrics and Landscape change processes in the Gorganrood watershed in Golestan province.  Methodology: First, land cover maps were prepared in 1990, 2000, 2010 and 2020. Then predict land cover changes for future conditions, under two scenarios (1) continuation of the current trend of change for 2040 and (...

Not only have recent global challenges including drought, climate change, land degradation and land use change impacted the quantity of available surface water and groundwater, but also water quality has been affected as well. To study this impact, Landsat 5 satellite images and water quality data were obtained to compare the effects of land use changes on surface water quality between July of ...
