Abstract

the amount of water in the area and vegetation cover. In the present study, changes in the percentage of land cover and land use during the period from 1990 to 2016 were evaluated in the upper basin of the Alavian dam. For this purpose, at first Landsat satellite images were selected, the best band combination was prepared, and the land use map was mapped using the automated logistic support algorithm of the monitored classification, then the land cover map was classified in five classes. In order to evaluate the accuracy of the classification results, the production map was compared with the ground reality map and kappa coefficient and the general classification accuracy was determined by the automation classification method. Based on the results, roughly 1294. 86 hectares of gardens have been grown in the range from 1990 to 2016, where the water consumption for these gardens based on the NETWAT software indicates that about 11836174. 2 cubic meters per hectare per year, increased water use in the basin upstream of the Alavian. Also, simulation of Land use changes was done using Markov chain model and Markov chain auto-cells. The results of the research indicate that the gardens will reach from 2670. 06 hectares in 2016 to 3041. 555 hectares in 2021, which will be an increase of 371. 49 hectares. Ultimately, estimating these changes will imply a continuous reduction in the input of water into the reservoir and its degradation in the supply of drinking water, industrial and agricultural areas.
