Mohsen Bagheri Bodaghabadi; Mohammad Jamshidi; Zohreh Mosleh

Volume 74, Issue 4 , March 2022, , Pages 703-718


  Soil organic carbon (OC) is one of the most important soil properties, especially from an environmental point of view. For this reason, OC modeling and estimating has been highly considered. In modeling, application of pedotransfer functions to estimate soil properties from the other ones have an important ...  Read More

Evaluation and determination of factors affecting erosion and sedimentation of watersheds, case study: Urmia Lake basin

Mohammad Tahmoures; davud nikkami

Volume 74, Issue 4 , March 2022, , Pages 771-784


  Erosion and sedimentation phenomena are two inevitable phenomena of watersheds that are subject to complex factors. Identifying these factors and recognizing their effect on erosion and sediment will help in better planning to reduce the damage caused by erosion and sediment in a basin. In this study, ...  Read More

Predicting and detecting the trend of temporal and spatial changes of land use using land change modeler

Ali Azareh; Elham Rafiei Sardooi

Volume 74, Issue 3 , December 2021, , Pages 483-500


  The purpose of this study is to investigate land use changes in the past and predict future land use using land change modeler in Halil River watershed. The detection of land use changes was performed using Landsat satellite images (L5-TM-1991, L7- ETM+-2003 and L8-OLI-2020). Transition potential modeling ...  Read More
