  The establishment of each urban element in the specific location of the city follows special principles that if these principles to be considered well, will lead to the success and functional efficiency of that element in that specific location. In this context, the selection of a suitable location for the establishment of science and technology cluster as one of the urban distinctive elements has significant importance since those contain scientific, industrial, manufacturing, laboratory, research facilities, infrastructure and communication environments, institutions, individuals, and information based on creativity and innovation. Therefore, the present study was conducted aimed to find the most suitable location for the establishment of Yazd science and technology cluster. For this purpose after the study of global experiences and regulations and upstream documentation the requirements and necessities Clusters Site Selection were identified. Then, the effective parameters in two levels of main indicators and sub-indicators according to the Analytical Hierarchy Process Model were classified. Then, receiving information according to the experts, managers and professionals ideas analyzed by the Super Decision software and weight of the indicators was determined. In the next step, the satellite image of study area was prepared and using GIS, attempted for preparation of data layers based on requirements that come from the results of questionnaire and interviews. To achieve the final map that is obtained by overlaying weighted maps, first the importance of data layers in terms of distance has been determined and then using layers overlap method, Suitable location for the establishment of Yazd Science and Technology cluster has been proposed.

  Water scarcity in arid areas is a serious crisis. The most important step in using rainwater collection systems is to locate suitable areas. In this research, three methods of multivariate regression model and GIS have been used to locate the on-site and off-site rainwater collection method in Tejreh watershed. In this study, canopy, litter, rock and gravel, bare soil, CN, precipitation, slope and soil depth as independent variables and influence on in situ rainwater collection and maximum instantaneous discharge for non-in situ rainwater collection method The title of the dependent variable was considered. The multivariate regression model uses stepwise method, backward removal method, and forward method. And the standard step-by-step method, regression removal method, step-by-step method in collecting rainwater, non-in situ method have been used. The final results by matching the results of previous research show in step rainwater collection, stepwise method and between layers CN, soil, percentage of rock and gravel, and in non-in situ rainwater collection stepwise regression method Standard and among layers the percentage of litter, percentage of canopy, CN, slope, percentage of rocks and pebbles, amount of rainfall, percentage of bare soil and soil depth are known to be important in the equation. Finally, the importance of rain collection sites was divided into four classes: very good, good, medium and poor. Manuscript profile
