1- Introduction: Among construction materials, aggregates have extensive applications in the production of concrete, mortar, and in the construction of roads, railroads, airports, bridges and dams. Due to weathering, bedrocks are converted to small fragments and then weathered particles would be transported by erosive parameters such as water, wind, glacier and gravity and finally transported materials will be deposited in some geomorphological landforms. Some geomorphological landforms like river beds, river Terraces, alluvial fans, sand dunes, glacial outwash plains and taluses have large amounts of weathered rocks and sediments that are appropriate for aggregate exploitation. Pataq and Qalehshahin catchments as study area are the upstream subcatchments of Alvand basin in Kermanshah province, and are parts f Folded Zagros structural zone. The aim of this research is to define landforms that are appropriate for aggregate exploitation and to determine the effect of geomorphological processes in the formation and quality of aggregates.

1-Introduction: Climate change is one of the big challenges of human and is accounted as a serious threat for the earth planet. Increasing global temperature will cause deep and wide changes in the climate and especially in the time and space of precipitation and storms. Many studies have approved the occurrence of these changes, and the amount and intensity of them. In most of studies, statistical models (based on historical data) or Atmosphere-Ocean General Circulation Models (AOGCM) determine the increase of carbon dioxide emissions and subsequent changes in air temperature and precipitation. Then the changes in river flow rate cased by climate change are calculated by using rainfall-runoff models. But many of these studies only use a limited number of models and emission scenarios that may not include all the facts. Therefore in this study the results of 20 AOGCM models have been considered to explain the climate projection of time horizons 2040, 2070 and 2100. Also a big range of emission scenarios have been studied and using the selected scenarios and models, the amount of Sheshpir River flow (one of Zohre-Jarrahi river basin branches in the south west of Iran) has been detected.

1-Introduction: Urbanization is as one of the most important affected factors on personal and social health of citizens. So that, human health influenced by social - economic and their environment situation largely and depended on the plans and purposes which the city considered for them and so improving the urban quality of life, is depended on promote the health. Rapid urbanization and paying attention to physical concepts and disregarding the social goals in the urban development plans, cities has encountered with undesirable cycle of social- economic environmental imbalances and in total, declining the quality of life. Now, planners and urban decision-makers have decided to pay attention to and focus on the issue of urban quality of life, find a solution to make of human free from these problems. Despite the importance of quality of life in the urban development process, has not been much attention to this important issue, due to rapid urbanization and the need to urban development especially from the 80 decade and also due to poor vision in the right direction and control of urban development in Nour of Mazandaran and face to the problems so weaknesses in the quality and quantity of services, public and welfare spaces as municipal standards, lack of attention to environmental issues and the imbalance between social welfare and economic efficiency (in favor of economic efficiency) and... that in total, the urban quality of life has encountered with difficult.

1- Introduction: Usually urban areas with rapid growth and horizontal developing are occupying unsuitable topography lands with high geomorphologic hazards. Recently, most cities due to physical limitations on urban development encountered with in subject of physical developing (Garklou et al, 1390: 99). In other hand, urban development often caused industrial and technological crises and increases vulnerability of the city, due to the building, financial and citizen’s density (Asgari et al, 2008:36-37).Therefore, knowledge of the characteristics of urban environment is the important subject in urban planning and urban management. Irregular development of the urban has a destructive effect on natural landscape and on the fringe agricultural lands (Batisani and Yarnal, 2008:2). So to optimal site urban selection is trying considered effects of various parameters (Zhao, 2010: 246), Sareyin tourist town are located in the eastern mountain slopes at elevations between 1640 to 1740 meters and 16 kilometers east slope of Sabalan on the fault Valley in the city of Ardabil. Due to importance tourist importance in the past two decades has intensified the city's physical development. Therefore the importance of this research in the subjects of geomorphology and environmental hazards are identified for more appropriate land use.

1-Introduction: After the industrial revolution and growth urbanization, travel and recreation for spiritual needs of man has been converted as an essential tool which created a world phenomenon in recent decades that called tourism industry. This industry was a third largest economic phenomenon in the world after oil and the automobile industry. In different countries, urbans areone of the most places visited by tourist and around the world large cities constitute the most important tourist destinations. Urbanization has led to expand tourism industry and due to increase income, increasing leisure time, accessing and communicating facility. Urban environments are the source and destination for tourists. The Tourists arriving to a place can does significant influences on economic, social, and cultural in the environment and procure development in Region. Therefore, this justifies the need for planning and development activities. The purpose of this article is study of Feasibility of tourism development in Metropolitan Shiraz for Getting the right decisions in the planning and determining the appropriate strategy for prosperity and sustainable development in dimensions of the region and country.

1- Introduction: Tourism makes up a large part of the global economy and often as a key to economic growth in both developing and developed countries is used. One of the factors that should be considered in tourism is climate. Because in many countries of weather and climate are considered a capital value for tourism. But until now the source of tourism, tourism has a major role in the educational literature. Since much of modern tourism based on the use of natural features-is based on physical, development of tourist sites was not dependent on one source; it involves a wide range of resources, especially natural resources. The climate is considered as a source of basic or supplemental.

1- Introduction: The role of employment in the vitality of modern urban societies’ life is not a mystery to anyone. Unemployment and the ensuing issues constitute the most complicated of current urban planning issues which give birth to a plethora of deleterious social, cultural, security and even environmental complexities as well as to some certain economic consequences which directly or indirectly influence all aspects of urban planning in a sense that one could say many of the problems and issues of urban societies result from ill employment structures.

1- Introduction: The engraved remains on stony parapets of cultural heritage of this country show rich civilization of Iran that protection and reparation of them is a duty of scientific teams with cooperation of related specialist. Geomorphology, geology and geophysics are including of this science.Bistoon inscription is located on long wall (famous broken part) of broken zagros on rough part which is called same name. Broken part, fissure, and thick lime of previous region (Paleoclime) pave way for destruction of engrave figure, which leads to solving process and to make solving holes. This study has been done with the following tools: GPS, topography maps and satellite images.

1- Introduction: Development and increasing tourism, especially ecotourism - related activities today has become an important issue The Promenade sources based on natural resources has been established in each regions and it is necessary maintain the dynamics this the resource to be considered seriously.Therefore, the ecological carrying capacity of these resources and provide appropriate solutions to use them in the planning system is seen as something important.

1- Introduction: Trust is considered as the most important factor in order paradigm and it plays a central role in the thoughts of such sociologists as Durkheim and Tunis. In micro and macro levels, it may make people’s negative and positive feelings evident. It is the most significant factor of social order and is deemed as one of the pillars of social property. Furthermore, the empirical study of trust in a society may be a feasible solution in order to achieve the higher culture of citizenship.

1- Introduction: Timing coincidence of plant growth and development to suitable climatic conditions is on of the main factor for spring safflower increasing yield. Thus determining and zoning of safflower planting dates is very important. The highest planted area of spring safflower is belonged to Esfahan province. Delay in planting of spring safflower cause faster development, earlier flowering and lower photosynthetic area and these consequently lower yield and yield components.

1- Introduction: Natural environment hasn’t permanently adjusted with urban expansion and human settlements. Many historical cities have been abandoned due to these Natural environment incompatibilities. The most effective factors of natural environment on urban expansion are topography, slope, weather, geology, hydrology and geomorphology conditions. By increasing of trend urbanization, cities need to vast territories for settling the population, these territories have composed of different topographic and geomorphologic units.

1- Introduction: In recent decades as the population in cities of country, which had been influenced by natural population growth of cities and migration of people in towns and rural to middle cities and metro polices, increases city spaces and infrastructures, which are needed have not been equipped.Urban services are the means for managing urban development and a prominent cause in continuing city life, which without it the life of citizens has been stopped. Its optimal and systematic distribution consistent with the people’s demands in the process of urban planning is very important.

1-Introduction: Humans have been aware that weather and climate affect health and well being. Hippocrates, 2.500 years ago, wrote about regional differences of climate and their relationship to states of the health (matzarakis, 2007).In the several decades past, heat balance models of the human body have become more and more accepted in the assessment of thermal comfort. The basis for these models is the human energy balance equation. One of the first and still very popular heat balance models is the comfort equation defined by Fanger (1972).
