Introduction Developments and growth of urbanization and uncontrolled growth of non-standard textures and unbalanced spatial and physical growth of urban neighborhoods have caused many problems in all fields and the occurrence of various crimes caused by urban design disorders and inappropriate textures of urban neighborhoods. One of the major problems in urban planning, given the population growth and physical development of cities, is the guidance of urban settlements in accordance with the principles of location. Today, with the increasing expansion of various criteria and criteria of urban planning, there is a need to use models and software that can consider all these criteria and according to a combination of them, meet the various needs of urban managers. Research shows that criminals are often rational in their choice of crime scene and are looking for the least dangerous and appropriate opportunities for crime. Thus, in the city limits, centers are formed that have more criminal opportunities and targets, and consequently higher crime rates. Attention to the space, as a direct factor in the occurrence of crime, in comparison with individual or structural factors, makes it possible to think of more practical solutions to prevent crime. As a result, the aim of the present study was to determine the effect of residential use criteria on crime reduction in Tabriz metropolis. The need to conduct this research with the aim of changing and modifying some uses and more control over residential uses with complex physical elements that are vulnerable to crime and achieving measures to reduce crime rates in Tabriz and help to improve safety and security in society Was. The result of the question that in this research, considering the problems raised in Tabriz metropolis, made the researcher's mind investigate; It was a crime among the citizens. Methodology The present study is applied in terms of purpose and analytical-descriptive in terms of the nature and method of data collection. The statistical population included experts in the field of housing patterns in reducing crime in Tabriz metropolis in 1396. According to the Tabriz Judicial Statistics Department, 60 experts were randomly selected and answered the questionnaire on the impact of residential use metrics in Tabriz metropolis with ten regions. The measurement tool was designed as a researcher-made questionnaire that includes 48 items in a 5-item Likert scale for the identified indicators using crime prevention approaches in residential patterns, which in the factor analysis confirm the removal of 3 items and finally with 45 items were designed. Results and discussion The present article was conducted with the aim of influencing residential use criteria in reducing crime in Tabriz metropolis. The results showed that planning and physical actions, planning and social measures and planning and security measures of high-rise residential uses have an effect on reducing crime in Tabriz metropolis with different values. The second and social indicators are the last priority. As a result, paying attention to the environment and residential patterns in crime prevention can be fruitful. Most theories have focused on physical actions and planning for residential use patterns in crime. However, with the rise of buildings and the lack of control and access to units and residents, theorists turned their attention to social measures and planning in these places and benefiting from the interaction and cooperation of residents in increasing control in such places. Security was considered. Therefore, in the present study, the three criteria of physical, social and security measures and plans and their indicators in reducing crime have been identified and evaluated by residential and criminology experts. Conclusion Based on the results of the present study on the effect of planned and social and security planning and residential measures on residential use reduction patterns in such places and in line with the theories and results of the mentioned research, it can be understood that due to population expansion And the lack of land to build residential areas in metropolitan areas, along with changing people's lifestyles and the increase in apartment living due to the consequences of modernity, as well as the advancement of technology and construction of towers and skyscrapers in metropolitan areas; For the construction of such residential premises in addition to construction and Legal instruments and attention to building strength and safety; in consultation with environmental criminologists and exchanging views with them, it is necessary to provide expert expertise in physical dimensions such as access control - environmental quality - natural monitoring and domination; social such as threshold capacity and social solidarity between Residents should consider preventing and preventing the occurrence of crime in such units. But these plans can be partially effective in reducing crime in these places. Residents also have responsibilities to improve the security of the building. As a result, paying attention to security in and around the building and neighborhood, along with physical and social planning, as a complement and catalyst can play a decisive role in reducing crime in such residential areas. One of the most important and effective interactions is mass monitoring as well as encouraging residents to participate.

Abstract Given the lack of information about the amount of snow in the highland area, the use of satellite imagery can be helpful in distributing of snow cover and resulted stream flow in water basins. The aim of this study is to investigate surface runoff at the Dehgalan basin outlet associate with changes in snow cover in the highlands of the basin. To this purpose the Values of runoff resulted from snowmeltin Dehgalan basin were simulated using snowmelt runoff model. In order to simulate, first climatic and hydrometric data were collected from Iran meteorological organization and Kurdestan Regional Water Co and then physical characteristics of basin include perimeter, area, and high zones were calculated using digital information. Climatic and hydrometric information were obtained from linked organizations. The ratio of basin snow cover was prepared by the SNOWMAP algorithm using 8-day snow cover products at the global scale bands of MODIS snow cover data from NASA site. The information that was essential for modeling were entered to model and simulating process was done according to the requirements of the particular specification of catchment. The assessment parameters that were used by model to evaluating the accuracy of the simulation included the coefficient of determination and volume differencing. The procedure of simulation of runoff resulting from snowmelt was conducted by calculateion necessary factors and parameters in the time period of December 2004 to April 2005. The results of simulation showed that snowmelt-runoff model was efficiently capable to simulating runoff from snowmelt in Dehgolan basin by 52% coefficient determination and volume difference of 2.23. The obtained correlation coefficient and difference of volume shows the mean accuracy of model in simulation of snowmelt- runoff in the basin. It could be caused by the physical characteristics of the basin. The results of this study showed that the operation of SRM model in study area as a coupled of mountainous and plain basin was less than mere mountainous basins.
