        In today's cities, housing has a large part of urban utilities, as well as housing, which consumes a lot of energy and resources imported to cities. Hence, housing sustainability is an important step in achieving sustainable urban development. At the present study with a descriptive-analytic approach with the aim of evaluating the indicators of physical sustainability of housing in two regions 2 and 4 of Tabriz city, Using the Fuzzy AHP model in the GIS software, we evaluated each of the individual physical sustainability criteria. With the formation of the paired matrix, the weight of each criterion was obtained and then, by integrating the criteria based on the weights assigned to them, in the GIS map of the overall sustainability of the buildings in the two regions was achieved. In region 2, the high sustainability floor has the largest area of the region, which is 315 hectares (ie, %71 of the area of the region's housing). And the very sustainable floor has only %1 of the area in the region. While the floor with a high and very high sustainability, in Tabriz region4,was only %3.48, and the floor with moderate sustainability with an area of 437 hectares accounts for%68 of the total area of the 4th region. The class with moderate physical sustainability in region 2 has about %8(27 hectares) and in region 4, covers about %27 of the area. Therefore, the residential region of Tabriz 2nd region has higher levels of physical sustainability than region4. Manuscript profile

        Human earthquake, over time, faced with irreparable damages. Decision-makers have always tried to manage the crisis and challenges arising from it. Therefore, assessment of vulnerability of urban areas and planning to reduce these damage is necessary. This research was conducted with the aim of assessing the urban area against earthquake and with the crisis management approach in Tehran 6th area. For this purpose Valued, 11 criteria for degree of confinement, construction density, building quality, population density, materials and structure of the building unit, access to health centers, width of the road, building height, land use, maximum horizontal acceleration of the land and the age of the building by Delphi method. Subsequently, the indexes were analyzed using the IHWP Hierarchical Model and the criteria were overlapped in GIS software. The results of the earthquake vulnerability map showed 4.8% of the area in the vulnerability class was very low, 19% in the vulnerability class, 46.2% in the middle class vulnerability, 25.4% in the vulnerability class, and 4.6% in the vulnerability class. The vulnerability class is very large. Regarding the Vulnerability Map of Area 6, we can find that areas with a higher-wiring network and low-density distribution of low-density constructions tend to be less damaged, most of which are located on the periphery of the region or north of the 6th area. Existing districts in the north of the region are less vulnerable than the rest of the study area. As you move from north to south, the vulnerability increases. Manuscript profile

        This recent study in Talequn catchment, placed in Alborz province, has been performed to prioritize affecting peak flow areas and generally areas that have a greater role in flood occurrence. To do this task, Arc Gis (Geographic information system) has been utilized to prepare maps of physical properties of Talequn basin catchment and also rain gauge date and equivalent run off statistics of Tehran regional water, for 20 years(1993-2013) has been received. As a result of existing data, four flood events were extracted and were calibrated under the (HEC-HMS) model. TO do calibration, SCS method was used to simulate flood hydrograph and lag-time method was utilized for channel routing. Also, Hydrologic Modeling System (HEC-HMS) was used to estimate the amount of contribution of sub-basin in output discharge of the total basin catchment on the basis of return periods of 2-5-10-25-50-100 years old and finally by the use of the 50-year return period and sub-basin individual remove method under the effect of HEC-HMS model, sub-basin were prioritized in terms of flooding potential. The research results show that sub-basin participation rate in output of basin catachment discharge is not only of affected area and sub-basin peak flow but also of factors such as curve number (CN) and soil hydrologic group which have significant role in flood occurrence. Another significant factor is sub-basin located in basin output, which has greater share in output discharge. In addition, short intervals in occurrence of peak flow of sub-basin water flow synchronization role, human changes such as construction activities like housing, have significant impact on the production of the whole basin flood areas.

        Abstract Natural disasters annually cause an average More than a thousand billion damages to the country. According to experts, Iran is one of the most prone areas of the earthquake and according to official statistics in the last 15 years, 6% of the earthquake casualties were earthquake. In this regard, assessing the seismic vulnerability of different regions of the country in order to reduce the vulnerability of urban communities should be a priority in planning. The purpose of this study was to investigate the role of topography in magnifying seismic effects in the Kalat-Naderi area of Khorasan Razavi province using Pessina et al. In this regard, first, the digital elevation model of sites prone to magnification of geomorphological effects was investigated. These effects included: ridge, peaks, hills, valleys with features such as slope shape, as well as slope and elevation difference. GIS functions were also used to classify critical areas. The resulting maps can be used to assess large-scale topographic areas of risk and earthquake risk. According to the results of the study, out of the total study area, 74.71% were in the range of low magnification, 21.12% in high class and 4.15% in high class. Manuscript profile

        Soil erosion and sedimentation are among the major limitations in applying water and soil resources. Thus, the assessment processes that govern their behavior in order to better understand watershed systems and explain proper management practices are essential. This study is therefore aimed at studying erosion in the watershed of Shahriar Dam in Mianeh, East Azerbaijan Province. In view of the recent conditions of formations, a sedimentation rate is very high in this dam. Evidently, these sediments fill the dam reservoir and lead to a reduction of the dam life time. As a result, studying erosion and estimating upstream erosion and sedimentation are necessary. Consequently, one of the principal goals of this survey is determining the level of sensitivity of formations to erosion and their roles in formation of new sediments. To achieve this aim, the border of Shahriar Dam’s watershed was determined by using 1:50000 topographic maps of Zanjan, Mianeh and Hashtrood. This region was carefully implemented on 1:250000 geological maps of Zanjan, Mianeh and Hashtrood. Maps of channels, geology, vegetative cover, faults, amount of rainfall, and regional topography were digitalized. Next, the erosion intensity was examined in the above-mentioned basin using GIS and marking and layer integration methods. On the other hand, in order to estimate the rate of erosion of present formations in the watershed basin, EPM method was used. It was revealed in this study that erosion-sensitive units were largely located in the northern and southern areas of the basin; however, there are erosion-prone rocks in the western part too. Based on the existing indices of GIS, total amount of sedimentation of the watershed basin of Shahriar Dam is medium. Moreover, according to EPM model, the coefficient of erosion and sediment yield (z) for this basin fall into very heavy erosion classes. for this reason, the sediment yield in the basin was high and put at somewhere close to 60,000 tons per hectare annually; and according to the zoning map of erosion, much of the sediment comes from segments of the zoning was done in this research area erosional is placed high. The final model represents the fact that lithology, land cover and stream erosion play a major role in controlling erosion and sediment yield. Manuscript profile

        During the past decades, recognition of human activities has attracted the attention of numerous researches due to its outstanding applications including smart houses, health-care and monitoring the private and public places. Applying to the video frames, this paper proposes a hybrid method which combines the features extracted from the images using the ‘scale-invariant features transform’ (SIFT), ‘histogram of oriented gradient’ (HOG) and ‘global invariant features transform’ (GIST) descriptors and classifies the activities by means of the deep belief network (DBN). First, in order to avoid ineffective features, a pre-processing course is performed on any image in the dataset. Then, the mentioned descriptors extract several features from the image. Due to the problems of working with a large number of features, a small and distinguishing feature set is produced using the bag of words (BoW) technique. Finally, these reduced features are given to a deep belief network in order to recognize the human activities. Comparing the simulation results of the proposed approach with some other existing methods applied to the standard PASCAL VOC Challenge 2010 database with nine different activities demonstrates an improvement in the accuracy, precision and recall measures (reaching 96.39%, 85.77% and 86.72% respectively) for the approach of this work with respect to the other compared ones in the human activity recognition.

        Wastes pollution is the source of many environmental problems. These pollutants cause water, soil and air resources pollution and destruction of natural landscapes and spread of disease, while waste disposal centers pose a threat to rural areas, despite the appropriate distance from urban centers. Determining areas suitable for landfills is one of the general strategies to deal with this crisis. In this research, which has been done by descriptive-analytical method and relying on library resources, after collecting raw layers related to 12 indicators (rural, urban, roads, water resources, floods, land use, pastures, soil, geology, faults, communication roads, etc.) and preparing distance maps and its scaling were investigated using linear software in GIS software of suitable areas for waste disposal in Qasr Shirin city due to its special location in terms of abundant water resources (mineral water and ecotourism). The results show that most of the city of Qasr Shirin is not suitable for waste disposal, these areas are shown in red in the final output of the models. Also, only the parts of the city are suitable for this purpose, which are marked in blue in the final output of the models. Manuscript profile
