this study aims at identifying the suitable areas for ecotourism using geographic information system (gis) and analytical hierarchy process (ahp) in experimental and educational kheyroud forest, nowshar, mazandaran province. the evaluation process was conducted based on three groups including ecological, infrastructural, and socio-economic criteria. then, the indicators of each main groups were...
the present study was an attempt to compare the effect of peer metalinguistic corrective feedback on elementary and intermediate efl learners speaking ability to see which level benefits more from this type of feedback. to this end, 117 female efl learners at grade 3, al-zahra high school in kermanshah, iran were non-randomly chosen. the homogeneity of the participants was attained through a pi...
Background and objective: Landslide susceptibility zoning using different methods is one of the landslide management strategies. The purpose of this study is to evaluate the landslides susceptibility in the Bar watershed in Khorasan Razavi province using the support vector machine (SVM) algorithm. Method: First, the landslide layer of the area was corrected through field visits and Google Earth...
Soil erosion and sedimentation processes can be considered as serious eco-environmentalproblems. This study aimed to estimate the basin-wide erosion using the Revised UniversalSoil Loss Equation (RUSLE). The soil erosion parameters included rainfall erosivity mapgenerated from the rainfall data, soil erodibility extracted from the soil map, land cover andmanagement map produced from supervised ...
Slope instability research and susceptibility mapping is a fundamental component of hazard management in decreasing the risk of living with landslides. Landslide susceptibility is defined as the proneness of the terrain to produce slope failures and susceptibility is usually expressed in a cartographic way. The Dena city in Iran is a landslide prone zone because of its own characteristics inclu...

Economic and therapeutic value of medicinal plants have encourage the people to increase cultivation of these plants in the world. Glycyrrhiza glabra is one of Iranian native plants which is used in the food, pharmaceutical and tobacco industries. The aim of this research is to identify suitable lands for cultivation of Glycyrrhiza glabra using ANP Fuzzy method in Ligvanchay watershed, Ardabil....
erosion is one of the important factors in soil degradation and decrease fertility and slope length is one of the most effective factors in land form and amount of erosion. the objective of this study was investigation of spatially variation of sediment concentration in slope length until to receive transport capacity. to obtain this goal a hill slope simulator system designed and manufactured....
