Abstract
Natural disasters, which are part of the process of human life and their number and diversity are increasing every day, are a major challenge to achieve sustainable development of human societies. Hence, the prevailing view of focusing solely on reducing vulnerability to increasing resilience to disasters has shifted. The purpose of this study is to explain the components of urban resilience against natural hazards with emphasis on floods in Behshahr. The research method in this research is descriptive-analytical and in addition to documents and library studies, a questionnaire was used to collect information. The statistical population of the present study includes two groups of citizens living in the neighborhoods around the four rivers of Behshahr. After collecting field information that was completed using a questionnaire tool, from SPSS, MINITAB and PLS software and using multi-criteria decision making (SAW) methods to investigate the situation and explain the components of urban resilience in Against natural hazards such as floods and GIS software was used to zoning areas based on flood resilience. The results show that among the dimensions of resilience, the economic dimension has the highest weight and is in the first place and the physical, infrastructure and environmental dimension has the lowest weight and is in the last place. Neighborhoods around the rivers of Behshahr city are ranked based on flood resistance status, which shows that Shahed neighborhood is in the first place and Borzoo neighborhood is in the last place.

Abstract
Urban Regeneration is the one of Restoration function that imports to four dimensions of Form, Economy, Society and Ecosystem. Environment Quality is the one of objects of Urban regeneration. On the other hands lack of peoplechr('39')s interest to live and spending leisure time, the quality of city center decreases and it is more important to increase quality of city center. Environment quality is general subject and, in this study, we use creative model place for describing quality factors of environment. Golkar`s model “sustainable place” which comes from Canter`s Model “Place” is the one of most complete models for assessing the qualities of environment; It imports to four dimensions of form, activities, imaginations and ecosystem after that eventually we can obtain the Conceptual Framework of central part of Urban regeneration based on Environmental Quality. By means of content technique, various ideas and views about environment qualities from global theorists, Experiences of regenerating city center and national restoration document were collected then calculate average of them for selecting most important of them. Finally define Measures for all these important qualities to draw Conceptual Framework. The result show that legibility and Visual character are the most import qualities of empirical-aesthetic factor, Permeability and Socio petal space and Quality of public area and Vitality are the most import qualities of functional factor and Compatibility with nature is the most important quality of ecological factor. These 7 qualities which are among the most important qualities must be considered in regeneration of city centers.

Abstract
Kermanshah province, especially Ravansar city is one of the important regions of the country in the agricultural and horticultural sector, most of the time the hail phenomenon causes significant damage to these sectors. One way to reduce this damage is to install an anti-hail system. To achieve this goal, 37 station hail data were clustered and three main clusters were obtained representing hail days; Each of the clusters has been plotted and analyzed in terms of geopotential height of 500 hPa, moisture level of 700, and map of 1000 to 500 hPa of temperature and omega. The results of the study of hail patterns show; A low-altitude system is essential in the Middle East; To direct hot and humid air from the southern offerings to the region; At the same time, it is necessary to have high instability and weak static stability in the atmosphere on the surface of the earth, as well as the presence of sufficient moisture that can provide showers. Hierarchical analysis (AHP) method was used for location in GIS environment and parameters such as (slope, slope direction, temperature, humidity ...) were evaluated. These criteria were classified as operating maps, each separately and were scored according to the degree of priority in establishing the device. The final map shows the location of the system: Parts of the northwest of the region (Mansour Aghaei and Ghori Qaleh) and northeast of the central part of Ravansar and parts of the southwest of the area due to the appropriate geographical conditions and appropriate to them, sufficient temperature and humidity and the direction of the southwest slope, and having Favorable conditions for severe instability followed by hail; Anti-hail system is very important for construction in these areas. In general, about 32.6 square kilometers have relatively favorable conditions and about 3 square kilometers have very favorable conditions for the construction of the system.

Abstract
Utilizing neighborhood capacities and redefining the role of citizens at the urban neighborhood level has led to a new approach called neighborhood-based participation; Because many urban challenges are rooted in the lack of citizen participation. The city of Zahedan is no exception. In order to achieve neighborhood-based participation, it is very important to pay attention to and strengthen some indicators. The purpose of this study is to measure the effective indicators in improving neighborhood-based participation to improve urban services in the city of Zahedan. The research method is descriptive-analytical and based on data collection in the field through a questionnaire. The statistical population of the study consists of 587730 citizens living in Zahedan. The sample size was calculated using the Cochranchr('39')s formula of 322 people. Examination of 5 variables of reliability, accountability and responsibility, reliability, empathy and attention and tangible and tangible factors show that all 5 variables were significant at the level of less than 0.05. Examining the difference between the mean and t-test statistics confirmed that citizens do not trust the performance of the municipality and managers. Also, one-sample t-test shows that the indicators of transparency, empowerment, economic base, value bases and sense of place are equal to 0.000 and less than 0.05 are significant. This article points to the impact of these indicators on improving neighborhood-based participation. Based on the results of the structural equation model, the greatest effect is related to the transparency index with 0.19, then the sense of spatial belonging with 0.15. Also, one-sample t-test shows that voluntary contributions (mean difference of 0.510), financial (mean difference of 0.611) and intellectual (mean difference of 0.486) with a significance level of less than 0.05 can have a great impact on Improve neighborhood-based participation and improve the quality of municipal services.

Abstract
| The role of regional and extra-regional forcings causes changes in the Siberian high-pressure cyclonic circulation every year. In this regard, an attempt was made to investigate the variability of the intensity of the Siberian high pressure in relation to the abnormal winter circulation of the atmosphere. For this purpose, gridded data of sea level pressure, geopotential height, orbital and meridional wind components of Center for Environmental Prediction/Atmospheric Sciences (NCEP/NCAR) between the years until 2020 (December to February) were used. After applying the Siberian high pressure intensity index, the extreme periods of this high pressure in winter were extracted. Next, the development of this system and the systems affecting the Siberian high pressure were investigated using the quantity of relative Vorticity advection. The results showed that during the winter period, the high pressure center of Siberia has undergone changes and has taken on a growing trend between 4 and 6 hectopascals. On the other hand, it was observed that the role of atmospheric systems such as dynamic ridges on the Siberian region along with advection The negative relative humidity, the location of the Siberian region in the east of the ridge, and the formation of omega bands play an important role in strengthening this system, which has caused this high pressure to develop from east to west or north to south. On the other hand, the role of the polar vortex in the cold advections of the region and the displacement towards the equator has caused the Siberian high pressure to sometimes increase by more than 11 hectopascals compared to its long-term average. Finally, it was observed that the atmospheric circulation in mid-latitudes plays a transitional role in the high pressure changes in Siberia and the polar and subpolar currents. |

Abstract
One of the problems of the cities around the capitals in the third world countries is that urbanization overtook urban development and this issue has created many problems in these cities. The lack of characteristics such as transparency, accountability, rule of law, participation, efficiency and the like in the urban management system also adds to the severity of the issues. The aim of the present research is to investigate the quality of urban physical-spatial development management with a good governance approach and to provide optimal strategies for the city of Shahryar. The research method is descriptive-analytical in terms of developmental and practical purpose, and descriptive-analytical in terms of nature. Data collection was done based on documentary and survey methods, and the tools of interview letter and questionnaire were used. Descriptive and inferential statistical tests, MICMAC software and SWOT model have been used in data analysis. The statistical population includes the city's citizens and the group of experts. Validity assessment was done using construct validity and reliability assessment using Cronbach's alpha method. The results show that the overall average status of physical-spatial development management in Shahryar city from the point of view of good governance indicators is equal to 2.006, which is in an average situation based on the Likert spectrum. The findings of the investigation of the influential factors on the quality of governance of this city with the help of MICMAC software show the stability of the system. Finally, the examination of the strategies for realizing the model of good governance in the urban management system shows the predominance of the strategy (Strengths and threats) in the urban management system of Shahriar, which is based on increasing the level of supervision, developing the capacity of the audit system and the headquarters to fight against corruption and violations. The administration emphasizes the fight against mafia and lobbying in urban management, the development of plans and programs for the renovation of worn-out city structures, the development of electronic technologies and tools, and the improvement of economic and human indicators of urban management.

Abstract
The more exposure to Climate change / variability, the more vulnerability and a community with low adaptive capacity and high sensitivity is more vulnerable. Vulnerability reduction depends on adaptation policy and strategies. Designing and assessing these strategies require climate vulnerability (CV) measuring. To produce a new CV index, as a main propose of this study, first: The score of exposure factor for two five span years was calculated based on four synoptic stations data (Zabol, Zahedan, Iranshahr and Chabahar). Second: The scores of adaptive capacity and climate sensitivity were determined using all of the country census and yearbook data for 1385 and 1390. Third: Due to the nature and factors of vulnerability, a climate vulnerability index was developed based on the multiplicative-exponential model (CVIMEM). Forth: The index was calculated for the province and sub regions. The result shows, although the Sistan and Baluchistan (SB) adaptation capacity was increased, but because of the increased exposure and sensitivity, this province is 16.3% more vulnerable. Area with very high vulnerability label expanded from 57.5% to 100%, which reflects the spatial expansion of vulnerability over SB. The overall result is that vulnerability reduction needs for accurate and continuous measurement, on the increase adaptation capacity and mitigate climate sensitivity.

Abstract
Nowadays, informal settlements has become a common challenge in many of cities particularly in Metropolises .On one hand, it is a spatial manifestation of social and economical inequalities and injustice at the local, regional and national levels. On the other hand it is the result of urban planning deficiency, absence of citizenship and inattention to social and economical needs of low income groups in urban development plans. In this research, in order to develop main strategies for enabling and regularizing Tabriz informal settlements by zoning the district one’s settlements of Tabriz municipality and identifying the low income and vulnerable zones, the social, economical, physical and environmental indicators have been used. Moreover, the data was analyzed by combining GIS and AHP models and three zones were reached. The research shows the socio-economical and environmental separation between vulnerable zones and others. The CDS strategy has been confirmed because of paying attention to participatory and community-based approach for enabling and regularizing informal settlements of Tabriz district one

Abstract
Urban form can be affected by diverse factors in different times. Socio- economic, political and physical factors are among the main contributors. So, one of the most important challenges of urban planners is measuring and identifying urban development pattern in order to direct and strengthen it to sustainable pattern and right direction. The case study of the present paper is the city of Yazd, a middle-sized city in the center of Iran, and the studied years are 1975, 1987, 2000 and 2010. To achieve the main objective of the paper, measuring Yazd growth and expansion by spatial metrics, it has used remote sensing data and satellite imageries and ArcGIS software. The conclusion revealed that in four periods of study, complexity or irregularity of the urban patch shapes has increased, centrality or average distance of the dispersed parts to the city center has decreased, compactness or the number and area of patches their distance from each other has decreased, porosity or ratio of open space has increased and finally population density of city has decreased in a large amount. Therefore, all perimeters show that the temporal - spatial form of Yazd has moved from compact to sprawl. Due to many undesired impacts of urban sprawl, urban planners and authorities are required to use adherent techniques and policies to control urban sprawl and to direct it toward more sustainable directions.

Abstract
In developing countries, every year natural hazards causes major losses in urban and rural settlements. In this regard, it is noteworthy that in December 2004 bam earthquake caused widespread damages. With over 9 years passed of this crisis and reconstruction after that, it is important to assess the quality of reconstruction. So, the problem is that how is the physical quality of Bam that reconstructed. So, based on the theoretical framework, two hypotheses were offered. Then, based on the theoretical bases and previous studies, the operational definition of physical quality concept offered in three indexes and 40 indicators, and combined by AHP and SAW methods. Needed data gathered by households, experts and field questionnaires. For testing hypotheses used causal-comparative and correlation methods. Sample size calculated by Cochran's method (311 households). Sampling has done by cluster and random methods. Gathered data were analyzed by: One-way ANOVA and Tukey-test at first hypotheses; and correlations methods at second hypotheses. The results showed that the physical quality of reconstructed residential environment in Bam is different between various neighborhoods. Also, the results of correlation test showed that general physical quality have significant relation with literacy, income, occupation and socio-economic status at 99 percent of confidence. According to the findings, physical quality at society scale has socio-economical aspects. So, we must pay attention to this point seriously.

Abstract
Rapid urban development in social, economical, cultural, political and environmental aspects, has affected the human life in recent decades. Introducing the sustainable development as the main theme of the third millennium is the result of urban impact on the biosphere and the range of different aspects of human life too. Concentration on differences in dimensions and indicators of sustainable development in one place and having them compared to other places can use fal for planners to realize the development potential and weaknesses. In theme lines, Boroujerd city have been studied as one of the median cities in the West of Iran to assess the indicators of sustainable development. The purpose of this study is to assess indicators of sustainable urban development in Boroujerd town, compared with Iran urban centers. In this study, methodology, is cognitive in terms of objective, and is comparative- analytical in term of identity and the data collection method is documental studies. To assess the level of development, the concept of sustainable development was classified in four dimensions: social, economical, environmental, physical-institutional and 44 indicators were identified. The data were collected in the Boroujerd city and Iran urban centers. Data were analyzed with sign test in SPSS software. The result has shown that there is no difference between Boroujerd city and Iran urban centers in terms of social and physical-institutional indicators. But, economic and environmental indicators have significant differences. The economic condition is not good but the environmental condition is better. On the other hand, taking into account all indices, the sustainability of Borujerd city, almost is same with Iran situation sustainable.
