landsat data for 1992, 2000, and 2013 land use changes for ekbatan dam watershed was simulated through ca-markov” model. two classification methods were initially used, viz. the maximum likelihood (mal) and support vector machine (svm). although both methods showed high overall accuracy and kappa coefficient, visually mal failed in separating land uses, particularly built up and dry lands.there...

Understanding the hydrological process associated with Land Use/Land Cover (LU/LC) change is vital for decision-makers in improving human wellbeing. LU/LC significantly affects hydrology of landscape, caused by anthropogenic activities. The scope this study to investigate impact on Upper Baro Basin years 1987, 2002, and 2017. Soil Water Assessment Tool (SWAT) model was used simulation streamflo...

[1] In studies dealing with the impact of land use changes on atmospheric processes, a key methodological step is the validation of simulated current conditions. However, regions lacking detailed atmospheric and land use data provide limited information with which to accurately generate control simulations. In this situation, the difference between baseline control simulations and different lan...

with the increase in population and consequent increasing needs of society, land use planning is of particular importance. land use planning due to being involved with several conflicting aims, multi- objective evolutionary algorithm would be a useful tool to solve land use planning. but use of these algorithms should be examined according to the type of issues. in the study, addition to introd...

In this study the effects of land use change from salt affected land to cropland on soil quality indicators were studied in Chahafzal region, Yazd province, central Iran. Composite soil samples from 0-30 and 30-60 cm depths of saline and cultivated land were taken. Soil particle size distribution, calcium carbonate, Available water capacity (AWC), Electrical conductivity (ECe), Soil reaction (p...
