Given the abundance of desert and desert areas in Iran, it is necessary to recognize the basic capabilities of these areas to eliminate restrictions, prevent migration of people and achieve their sustainable development. KhoroBiyabank region is the tourism hub of the central desert of Iran. The aim of this study was to identify the most suitable place for ecotourism in Khorobiabank city and to identify the potential of the region in the field of various ecotourism activities. 30 questionnaires were completed by experts in this field and its results were used using hierarchical analysis in Expert Choice software to achieve the set goals. The results showed that the six criteria studied in order of importance are: 1- biological environment, 2- special values, 3- physical environment (geology and geomorphology), 4- socio-economic and political environment, 5- physical environment ( Climate and climate) and 6- Cultural environment criteria, the options of each criterion are Iraj village for the first criterion, Egypt village for the second and third criteria, Khor city for the fourth criterion, Iraj village for the fifth criterion and again Khor city for the sixth criterion.

AbstractRelate temperature change Problems, soil salinity and the sharp drop I groundwater levels on the one hand and the recent drought combined with the problems have let to the reduction of consumption in the agricultural sector due to the reduction of the crop production and the adaptation to alternative climates get current products. Recent study conducted for determining suitable zone for saffron in North Khorasan with GIS and model AHP. Parameters like climate data, soil and water for 30 years collected from synoptic and climatologic station around province and from four neighbor provinces. Then parameters weighted upon AHP in parameter importance each region. Data transferred to Expert choice and clustered, rated, integrated for producing the last layer. Results showed that 47.1 % of province land was suitable and moderate suitable for culturing saffron. But 35.99% showed critical suitability and the remined was not suitable for Saffron culture. Jajarm, Garmeh, Safia Bada, Esfarayen, Shirvan and Faroj plains are suitable places and Mane, Samalghan, Raz, Jargalan and Bojnourd plains are in critical suitability for Saffron culture.Keywords: drought, suitability, expert choice, land characteristics.

Developing urbanization and changing hydrological conditions of natural streams increases the flooding risk. This study tries to do flood hazard zoning in the Ilam city and determine the critical area of the urban regions against flooding by using AHP method and GIS environment. For this purpose, the parameters of the curve number, height, distance from the river, geology, land use, population, slope, soil, building density, worn texture buildings and accumulated flow as effective parameters in flooding hazard in Ilam city selected and of these parameters weighted by using Expert Choice software. The result of the Expert Choice software is transferred to the environment of GIS software and flood hazard map of study area prepared. Results of the study and flood hazard map show that areas with very low-risk, low risk, intermediate-risk, high-risk and very high-risk form the 0.8%, 8.5%, 49.6%, 32.54% and 8.56% of the of Ilam city area, respectively. Also, the central area of the city has the highest risk and the probability of occurrence of the flood due to the high density of population and residential areas in this area and its proximity to the seasonal rivers and old part of the city. Therefore, by examining the results of Expert Choice software, it is possible to identify the most effective factors in the occurrence of flood risk and prioritize them to address management solutions to eliminate or mitigate the effects of these factors.

Municipal waste disposal can lead to many environmental, social and economic damages requiring effective solutions to manage municipal solid waste (MSW). Moreover, biomass energy produced out MSW is considered as an important source of renewable energy. This paper is an attempt to compare and identify the priority ordering of four available technologies to convert urban waste into biofuels for the case of Iran using Analytic Hierarchy Process (AHP) method and Expert Choice software. According to the results Anaerobic Digestion gets the first rank in the priority ordering of urban waste conversion into biofuels.

IntroductionA landslide is a natural phenomenon that often occurs because of falling down or seamless and quick movements of volumes of sediment along the slope. It has such speed and extent that it may influence tens or hundreds of cubic meters of rock and soil together. This phenomenon causes a lot of economic damages to forests and their growth, farmlands, gas and power transmission lines, mines, engineering structures, and buildings. One of the best ways to prevent these damages is preparing a landslide hazard map.
MethodologyThe method used for zoning the Sardool Chay Basin is the Analytical Hierarchy Process. This is one of the most comprehensive multi-criteria decision methods, which was first presented in 1980 by Thomas L. Saati. This method is based on weighing each pair of variables with each other. AHP method consists of three main steps including (1) creating an Analytical Hierarchy, (2) comparing pairs of elements in it, and (3) weighing the criteria. The main feature of this method is the use of expert opinions. In AHP,n paired factors are compared with each other and more weight is given to the layer that has the maximum impact on the target set. The paired comparison of a scale, based on1 to 9, for its two component's relative weighing is hierarchical.
DiscussionIn this study, the landslide hazard zonation was used in the Sardool Chaycatchment in order to identify areas with landslide incidence potential. The main factors contributing to the landslide occurrence in this case study consisted of geology, land use, slope, aspect, rainfall, altitude, distance from faults, and distance from stream. Their layers were prepared in ArcGIS software. An Analytical Hierarchy Process in Expert Choice software was used for paired comparisons of criteria and calculation of final weight. The results indicated that the geology criterion, which weighed 0.343, and the slope criterion, which weighed 0.215, had the most influences on landslide occurrence.
ConclusionLandslide is one of the most common environmental hazards in mountainous areas of the northwest of Iran. Factors such as slope, rainfall, lithology, and earthquakes can trigger them. One of the best ways to deal with this phenomenon, before the implementation of any project, is the zonation mapping of the area. This study was based on the Sardool Chay catchment, located in Khalkhal, the southern part of Ardabil Province.
To this end, 8 factors including geology, land use, slope, aspect, rainfall, altitude, distance from faults, and distance from stream were used. The weighting factors and the Analytical Hierarchy Process (AHP), and the Expert Choice software were used. The results classified the basin into five areas including very high risk of landslides (65 km²), high risk (144 km²), medium risk (202 km²), low risk (142 km²), and very low risk (120 km²). In addition, it indicated that the landslide risk of the Sardool Chay catchment is medium. Comparing the landslide zonation map and points of distribution suggests that the AHP can be a good method of weighing the criteria involved in the happening of the landslide.

According to amendment of The project dams requires many credits for watershed management. Locating studies and prioritizes critical areas are Necessary before the dams must be done accurately and comprehensively. Accurately identify erosion areas in the sub watershed is essential and appropriate measures, including structural, non-structural subject or a combination of them can reduce the severity of the damage caused by erosion and sedimentation. Accordingly the following watershed basins in the execution of construction activities, determine priorities and policy requirements are, the most importance. In this study, 11 effective measures of the performance of Dams stone - mortar in the area identify. Weight by Expert Choice software, and implement dam priority sub watershed stone - mortar by the TOPS IS. According to the results of effective criteria for locating Dams stone–mortar, the criteria erosion, including sedimentation, and discharge in particular is the most importance with the weight of 0.132, 0.103 and 0.1. Finally the watershed dams to carry stone-mortar TOPSIS methods were prioritized. The results show that the erosion of the basin S 1 with 61.14 ton/ha in the first one and sub-basin S3-n is the last one for the implementation of stone-mortar dams. The administrative priority of structures is important in allocating targeted credits for the watershed step
