Abstract
In this study is simulation of role of topography in thickness and Inland penetration of sea-breeze in southern coast of the Caspian Sea. The RegCM4 as a regional scale climate model coupled with a lake model and also the reanalysis data of NCEP / NCAR used to determine of the initial conditions of the model. The model was run during the peak of sea breeze on the southern coast of the Caspian Sea (July 2002) in both conditions (with mountains) and (without mountains). the outputs indicated that in without topography condition depth of the sea breeze will increase to the current position the southern slopes of the Alborz Mountains ( latitude ᵒ35 ) but the land breeze in the area is gone. The maximum speed and changes in wind direction observed on the coast southeast and central Alborz respectively. In addition with non-topography conditions, the thickness of sea breeze in different areas significantly has increased with the highest rate on the eastern coast (longitude ᵒ53).

Abstract
Efforts to provide security have always been of great importance to human being. In recent decades, the security issues of climate change have attracted attentions due to its sustainable consequences on the lives and civilization of humans. Among all countries, the ones which are placed in draught belt, like our country Iran, have hurt a lot because of low precipitations and also mismanagements in water resources control. Climate change show itself by changes in precipitation patterns, reduction of precipitation and increasing of temperature. According to the present data, Iran's central drainage basin which consists of important geopolitical provinces, has been affected by the above mentioned factors. This descriptive-analytic research is carried out based on the effects of climate change on Iran's central basin which provides approximately 48 percent of Iran’s GDP. Continuity of climate changes in this region can make critical problems in social, environmental, economic and political scales and the lives of the citizens would be affected as well. To conclude, the persistence of the current conditions in climate change in the central drainage basin of Iran, would result in challenges through the national stability and security.

Abstract
Increasing CO2 emissions and consequently, air temperature causes climate anomalies which affects all the aspects of human life. The purpose of this study was to assess the temperature changes and also to predict the extreme temperatures in Gilan and Mazandaran Provinces. To do this, the SDSM statistical and dynamical model was used. As well, it was applied the Mann-Kendal graphical and statistical technique to analyze the temperature changes and its trend. In this regard, the daily temperature was obtained from Rasht, Ramsar and Babolsar synoptic stations during 1961 – 2010, and also the general circulation models data of HadCM3 and NCEP were collected from related databases. The results revealed a significant positive trend in monthly and annual minimum and maximum temperature in all three stations in the first (1961-2010) and third (1961-2040) periods. There is not a significant trend in extreme temperatures in Ramsar and maximum temperature in Rasht in the second period (2011-2040). The Mann-Kendal graphical test was used for the yearly extreme temperatures in all periods. The results showed that it was occurred both increasing trend and suddenly changes or shifts at the 95% confidence level in all stations. It is occurred the highest of changes in monthly and annual of the minimum temperature at forecasted period (2011-2040). It was predicted extreme temperature to increase about 0.1 to 1.7° C. The short time oscillations and significant positive trend occurred in both the maximum and minimum temperature shows the temperature increase and climate changes in the future. Thus it is obvious the decrease in temperature difference in warm and cold seasons.

Abstract
This study aims at identifying optimal method for masuring degree and level of development with resprct to models commonly used (Taxonomy, TOPSIS, Moris, SAW, and VIKOR). It is an applied rsearch in terms of the purpose and also is a quantitative research that was carried out in a survey method. Statistical population of the study was the villages in the county with 20 or more households (89 villages). Accordingly, 566 rural households were determined and selected as a sample using Lin sample size table. To collect the data, a questionnaire was used. For determining the content validity of the questionnaire, a factor analysis and for internal consistency reliability, Cronbach's alpha was used. The Cronbach's alpha coefficient (0.561-0.955) indicated the optimality of the questionnaire. Matlab 7.10, Excel2010, SPSS20, and Arc-GIS Softwares were used for modeling the level of rural development in the county. Findings revealed that there was high significant relationship between the methods with regard to their ranking scores. Findings showed that the VIKOR was a suitable and powerful approach to determine level of rural development in the county. In VIKOR, the range of development degree was very high with compaire to other methods. In VIKOR similar to TOPSIS, negative and positive ideals were considered. VIKOR has a differenc with TOPSIS in considering criteria weight, In VIKOR at first, distance of each criterion from ideal was calculated, then the weights were added them. Therfore, in VIKOR against SAW and TOPSIS has a high sensivity to the weights. Furtermore, findings showed that Sarabtaveh, Deh Bare- Aftab Olia, and Tangary with regard to 51 criteria by 0.635, 0.608, and 0.579 scores, respectively were developing villages and Gavbarg, Cheshmeh Tabarghoo, Tal-Gahi with 0.182, 0.201, and 0.233 scores respectively were non-developed villages. Also, there wasn’t any village in level of completely undeveloped, developed and completely developed. Also, approximately half of villages (46.1 percent) with 21.46 percent of the population of the rural region were undeveloped villages. In addition, 69.35 percent of population in villages of the study was in developing stage.

Abstract
Spatio-temporal variations of factors affecting the occurrence of precipitation can lead to a change in its amount. The atmospheric moisture is one of the most important factors for precipitation formation. In this study, changes in atmospheric moisture and its relation with occurrence of seasonal wet and dry periods were investigated in Iran. The re-analysis data from the ERA interim European Center for Mid-Term Projections (ECMWF) was used during the period 1981-2011. The z index (ZSI) was used to extract wet and dry periods of autumn, winter and spring seasons. The seasons with the maximum percentage of wetness/drought occurrence during the above periods were selected. Vertical integrated divergence of the moisture flux was extracted in three layers of the lower, middle and upper atmosphere above Iran. The results revealed that in all three layers, moisture flux was maximum during wet period and decreased in dry one. In all layers in wet and dry periods, the moisture content imported to Iran increased during warm season as compared to cold seasons. In addition, the difference in moisture content in the warm season was less than cold seasons and has less variations. There was no significant changes in moisture at high levels in three seasons. In general, there was a significant difference in terms of the winds pattern in the wet and dry periods. The favorable conditions of flow patterns on the water surface of the region provide the condition for increasing transport of moisture to Iran. Although, the moisture transfer reduced due to deviation and change of direction of currents, in dry period especially in the lower layer, and hence increase the occurrence of dry periods in Iran.

Abstract
The rapid expansion of cities and their uneven physical growth, so-called "urban creep", have corrupted the villages and their surrounding lands, causing irregular conversion of agricultural lands and degradation of environmental resources. This situation has also been widespread in Shahrekord, the capital of Chaharmahal and Bakhtiari province. The purpose of this descriptive-survey research is to determine the physical developments of rural settlements around Shahrekord with emphasis on urban sprwal. The statistical population is household heads of rural areas (15000 people). Using the Krejcie and Morgan table, 400 individuals were selected. The tool used is a researcher-made questionnaire on three dimensions of economic, social, cultural and environmental physical consequences. Data were analyzed using one-sample t-test and Friedman test. The results show that the consequences of urban sprawl are respectively environmental-physical consequences (3/98), economic consequences (3/96) and socio-cultural consequences (3/89 (. The most important environmental-physical consequences are increased environmental pollution, destruction of traditional architecture, destruction of biodiversity; major economic consequences of stock markets and rising land and housing prices, diminishing villagers' reluctance to productive activities (agriculture and livestock), capital flight from villages And their savings in the city and the rising cost of living amidst the socio-cultural consequences of luxury and the tendency to consume luxury goods, reduce solidarity and participation, crowding and crowding in cities, modeling of life and urbanization culture. have been.

Abstract
Awareness and understanding of the climate trends by farmers and the attitude towards the necessity of this awareness is one of the essential capacities in agricultural societies. Farmerschr('39') attitudes to climate information are affected by their behavior with the climate hazards and uncertainties and influence their decision on adopting appropriate strategies to minimize the damages caused by climate changes on agriculture and improve their readiness. Hence, the aim of the present study was to establish a comprehensive framework and model for the qualitative evaluation of studies discussing the factors that affect farmerschr('39') attitudes to climate information utilization with a systematic review approach. For this purpose, the following keywords, including climate, climate change, climate changes, meteorological information, global warming, drought, flood, chilling, frost, climate hazard, precipitation, temperature with the aid of the following keywords namely, farmer, farmerchr('39')s attitude, farmerchr('39')s perception, farmerchr('39')s knowledge, and indigenous knowledge were used in both languages, Persian and English, among the articles published between the year of 2000 and 2019. After three stages of screening 788 related articles and according to approved criteria, 25 scientific and research articles were selected and explored. After qualitatively evaluating these articles, a model with five bio-environmental, individual, social, economic & technological factors as well as 19 dimensions has been proposed to evaluate the factors affecting farmerschr('39') attitude towards using climate information. Finally, to apply the results of this study, a unified conceptual model is presented that can be the strength of the existing frameworks in making the national agricultural policy.

Abstract
Along with the development of cities and increasing population, many challenges have been created, the most important of which is urban transportation. The inability of traditional urban management to address this challenge has led to some approaches, including intelligent transportation. Adopting and implementing such an approach in metropolitan areas requires a change in management approach, of which integrated urban management is known as the most important. The purpose of this study is to investigate the status of integrated urban management and then its impact on the realization of intelligent transportation in the city of Zahedan. The research method is descriptive-analytical and based on data collection in the field through a questionnaire. The validity of the instrument and its reliability was confirmed by Cronbach's alpha greater than 0.70. The statistical population of the study is urban experts in Zahedan. The sample size was set at 100 people. The result of the one-sample t-test shows that the variables of integrated urban management are significant at the level of less than 0.05. From the statistical point of view, the 7 variables of good governance, synergy, unity of urban command, context, interaction, organizational structure, and systemic perspective are not in a good situation and these conditions have caused the integrated urban management index in Zahedan to not have favorable conditions. Also, the significance of the test shows that the 5 variables of intelligent transportation, namely intelligent monitoring, intelligent payment, intelligent violation registration, intelligent information, and mechanized fleet management are significant at the level of less than 0.05. Significantly, it indicates the unfavorable situation of the intelligent transportation index in Zahedan. Regression showed that integrated urban management variables can be more than 68% effective in the realization of intelligent transportation and 32% are dependent on other factors. The variable of good governance with 12% and then the systemic perspective with 11%, has the greatest impact in this regard.
Keywords: integrated management, intelligent transportation, Zahedan city.

Abstract
Cities are open systems that constantly change and bring about changes in inside and outside neighboring areas. With the rapid growth of urban population in the world, cities sprawl and occupy surrounding lands. In this situation, attention to the developments inside urban space could be a key principle in urban planning. The aim of this study was determining and prioritizing economic, social and ecological factors which influence inside urban space indicators in City of Gorgan using Delphi method and literature review. Following the increase in population, developments inside urban space in the future is inevitable. Understanding and recognition of this process is essential to effective management in the field of conservation of the urban environment. Four expertize requirements should be taken into account: knowledge and experience of the field of study; ability and willingness to participate; adequate time to participate; and effective communication skills. Experts’ panel included fifteen specialists from municipality, city council, academics, cultural and medical service providers, police, urban planners and citizens, whose points of view were collected using questionnaires. Data collection for questionnaire was repeated 4 times to reach a consensus. Overall, twenty - four factors were identified for the economic, social and ecological factors, and then the degree and percentage of importance for each one was determined. Results showed that the most important indicator is feeling of security followed by the noise pollution and environmental pollution. Results could be helpful to urban planners and related organizations to improve inside urban space for welfare and life quality of citizens. Prioritization of these indicators provides an appropriate action agenda for the managers.

Abstract
The science of urban planning, like other sciences, has been influenced by different intellectual currents. The origins of Folding urbanism, which owes much to philosophy in rhizome, based on Leipnitz mathematics, emerged in architecture by Peter Eisenman, which today survives on an urban scale with postmodern feminist literature as anti-Oedipus and anti-Freudian. Gives. Folding urban planning can be studied in three levels of geography, landscape and city. In this research, landscape and city levels are discussed. Objective: In this research, the evolution of folding is based on Foucault genealogy, which deals with the holes of history and power relations. In the field of urban planning of these relations, the ontology of urban topology layers according to Riemannian equations and Deleuze philosophy in the works of architects such as Peter Eisenman, Zaha Hadid, Eric Owen Moss, Charles Jenks, James Wines. The research method in this paper is descriptive-analytical with a combination of inductive and deductive. The process of this research has reached the conclusion that Folding urbanism is based on Mendelbrot fractal geometry, Lotfizadeh fuzzy logic and in Lawrence chaos atmosphere and power relations in the glory of feminism and its manifestation on urbanism are the main reasons for the formation. Urbanization is a folding. Results: Similar theories used in folding architecture, rhizome, anti-Oedipus, Mobius, hermeneutic cycle, theories have been formed that are closely related to Gestalt psychology and the phenomenological view that is hidden in the philosophy of unity in plurality. In these theories, the component is folded in its entirety. The skyline, the accesses, the views and all the architectural reserves form a whole unit. Theories related to folding urban planning such as small-scale urban carpets in urban furniture have not been successful, but in single buildings have provided the desired philosophies and have been somewhat successful, and on a large scale in the city well phenomenology, unity in plurality , Contains rhizomes, anti-Oedipus and all the issues raised within it.

Abstract
Rivers are environmental forms that react strongly to changes in their bed, tectonic is the most important factor affecting morphology of the river, causing significant changes in river systems. In this study, using the digital elevation model (DEM), Geographic Information System (GIS) and Global mapper 13, we investigated the effect of tectonic activity on river systems in the eastern slopes of Mullah Daghi, southeast of Zanjan province, this The area is drained by Abhar river. Using the Digital Elevation Model (DEM) in the Arc Gis 10.2 software environment, required maps including geological maps, topography and…, Geological map of 1: 250,000 leaves of Zanjan was used to prepare the fault map. In order to achieve the research objectives, tectonic activity indicators including: are Mountain front sinuosity, basin shape, drainage density, longitudinal gradient of the river, River maze, basin asymmetry, hypersometric integral, the topographic symmetry of the basin and the width of the valley floor to the height. The combination of these indicators is achieved by the tectonic activity index (IAT). The results obtained through the Iat index indicate the activation of tectonic and neotectonic in the watershed of Ardejin and Abhar and the moderate activities in the basin of the zareh bash basin. The impacts of these activities on river systems that are different from the tectonic indexes in the studied basins, such as river meanders(main stream), coniferous formation (Ardejin watershed basin), tilt watersheds abhar and Ardejin and the shape of the basins (Basin elongation zareh bash)
