The Zayandeh-Rud Basin, placed in the center of Iran, is one of the areas with water instability problems. In the last decade, the water resources of the basin have decreased. Thus, that part of the length of the river in the middle and downstream of the water flow has dried or temporarily turned off, and the allocation of agricultural water to the agricultural lands of these sectors has decreased significantly. In this study, ground-level land use changes were analyzed through Landsat satellite imagery analysis in 2000, and 2014. These periods coincided with the periods before and after the occurrence of the instability of water resources in the basin. The researchers specified the research area and then divided it into three parts, naming upper, middle, and downstream. At the next step, these parts were compared in the form of 6 categories of use. According to the results, during the period, along with the occurrence of water resource instability, construction and residential land use across the rangelands has increased, and land use of pasture has decreased. Agricultural coverage has increased in the upstream, but it has decreased in the middle and lower parts. Besides, the empty and blank land use on the upstream has decreased, and it has increased in the lower parts. Regarding the results, some of the instability of agricultural water resources in the basin could be attributed to the expansion of settlements, increase in water consumption throughout the area, and increase in agricultural activities in the upstream basin.

One of the new problems is paying attention to environmental planning for sustainable exploitation of land resources and prevention of environmental issues that have been considered by researchers and managers recently. As much as this planning is based on objective facts and potentialities, achieving predetermined goals becomes more feasible. On the other hand, environmental planning tools have tended to achieve local-scale plans to reach more sustainable cities and townships. In this paper, local-scale development planning has investigated in Shandiz district located at Torghabeh-Shandiz city. The planning of the Shandiz district has carried out using the analytical process consisted of three stages of environmental planning and using the Geographic Information System (GIS). The first stage involves understanding the capabilities and potentials of the study area through the study of the current status. Issues, facilities, and constraints associating to each section are categorized and prioritized in the second stage. The third step involves drawing a vision, organizing the general goals, and defining the objectives. Regard to the priority of the studied factors, it was proposed spatial solutions in environmental units. Finally, physical-spatial development plans were developed to guide the regional changes according to the natural and man-made constraints and potentials.

Developing according to foreign investment in South Korea is an economic miracle of contemporary century. The evolution of economic miracle has been accomplished by complete success of spatial planning. The most striking feature of spatial planning in South Korea is its implementation. Using descriptive- analytical method, this paper will seek success procedure of South Korea spatial planning and basic role of government in order to respond three questions: how government of South Korea was able to achieve such successes? Applying spatial planning as a tool in this process, which role government play? And what doctrines have this experiment in order to apply in Iran? Spatial planning of South Korea implement in three scale of master land, regional and urban plan. Urban planning of Korea has a three-tier structure. Urban master plan determine long-term growth path and future image of city in the upper level, urban management plan present program of city with binding rules and objective details in the next level, and the manner of programs and necessary strategies implementation in the third level. Urban management plan, including zoning plan (land use), urban facility plan, Maintenance plan of the city (time-out texture) and detailed plan of regions, is an unique, thorough and so successful sample among different countries and its doctrine is exploitable for Iran which has no land use and urban facilities plan and no sufficient and necessary solidarity in the field of time-out textures and detailed plan. Administrative identical process, preparing all plans by executors and approving lower – rank plans by preparers of upper – rank plans are another striking feature applying in spatial planning system of Korea which is major factors of urban plans implementation.

Regional Foresight, which focuses on some of the specific land area in a given territory sub-national aims to achieve the desired future decisions, will be operational. This article examines the spatial organization of Settlement systems in Isfahan province And Presentation of the urban system in the horizon 1420. This paper tries to identify the key factors influencing the development process at the regional scale, producing both possible and probable scenarios to provide the in the next 25 years Isfahan province. This research is a combination of documentary and survey methods in terms of category and is based on new methods in the science of future studies, analytical and exploratory in terms of nature, which is conducted by a combination of qualitative and quantitative models. Structural analysis are used to analyze data by use of MICMAC software. The results indicate that the key and strategic variables of Isfahan province development in Horizon 1420 includes: the way of countrys macro management, the way of managing the province, water resources, inter-institutional cooperation, population,Research & Development, role of transnational Province, Investment security, Industrial Production and mineral, level of IT, Tourism,production technology. Based on the findings, Isfahan province in terms of arrangement space systems will face in the next 25 years with five main scenario: Radial scenario, a scenario dismissed Islands, a cluster scenario, the scenario of multi-center, network scenario. Among the scenarios planned, the network scenario we can see the functional spatial integration in the region and the development integrated and balanced space.

Drought changes for optimal operation management of water resources well is the sensible. That's why last round of very extensive research on modeling drought in the world and Iran is and using their water projects and has conducted numerous hydraulic. One of the goals dynamic systems modeling potential policies to improve system performance. Modeling SPI index as an indicator of the country's drought situation stations using radial neural network model for each station was done. Independent variables neural network, relative humidity, temperature and lack of objects, which were selected according to their impact on precipitation. SPI index is the dependent variable. In total period of 42 years calculated by SPI, 12-month and 348 standard score by calculating the SPI 24-month, 336 standard score is obtained for each station. At all stations, ETo values from January to July to December increased and then fell in July to its maximum level reached in all stations. The highest average monthly ETo values in Abadan and Ahvaz stations in July and 18/232 and 16/214 mm respectively happened.

Analysis and study of spatial structure and its relationship with regional flows changings is one of the most important issues in regional and country planning. In this paper we try to analyze the spatial structure of South-Alborz (that includes six provinces) based on passengers flow. In order to respond to questions and specific targets we used analytical-descriptive method. Also we used a lot of different statistical tests in ARC GIS and in order to analyze spatial organization of flows, we used another statistical test in UCINET and NET DRAW. This study is an applied and basic research and is a ex post facto. Based on findings the spatial structure of population (as a harmonious whole) has a relationship with passenger flows and these show a lot of forms and trends by time.

New models of development are based on tourism development and utilization from place – Space variations; therefore, identifying the capacity and capabilities of different geographical areas is in the center of development planning for fundraising and investment. In this context, the aim of this study is to investigate the feasibility of investment in the tourism sector with emphasis on Western Azerbaijan province. The research method was descriptive - analytical. Expert choice and GIS software for data analysis has been used. The results show that, about 12.45 percent of tourism areas have international and national range and about 18.68 percent have national and local range. Also, about 17.45 percent of the tourism sector has a range of appropriate local investment. Experts say that effective factors of tourism investment range are different (Thiel index equal to 55/0), and areas which are contiguous with city infrastructure and municipal services have a border range.

The process of proposing solutions to solve the problems of the capital, after undergoing different stages has reached to the law of feasibility study of transmission of the political center of the country and reorganization and decentralization of Tehran. The aim of this study is to address Article one of this law, and offering reorganization and decentralization pattern. The research method is descriptive and analytical and it is an applied research. Data collection was conducted by documents, and survey research. The results suggest that we should discard the first part of this law and replace it with the reorganization and decentralization solutions. Also the results indicate that items including lack of strict enforcement of existing laws, point-wise look to Tehran and not considering the urban area as a whole, lack of attention to the problematic aspects of centralization (economic aspects), lack of simultaneous development of organization and decentralization policies have all weakened the organization and decentralization policies to some extent. In this regard, the list of strategies were derived from literature review extracted and were screened using the Delphi method. Finally, 30 key strategies in the template of reorganization and decentralization pattern of Tehran was approved by Delphi panel members.

One of the critical issues related to sustainable urban in twenty-first century, is the growth and development of the city in space and on this basis, the civil management was forced to think about urban development. Tehran metropolis with its growing, developing immersive and without physical, environmental instability surrounding the statue has arrived. One of the ways for decentralization and redistribution of the population and facilities thought in spatial planning is the, urban development and building new settlements around the metropolis which must meet the criteria of environmental, social, economic, physical, geographical distance, etc. be considered in studies not lead to environmental catastrophes. The method of this research is descriptive-analytical and its target is applied using the K-means and FCM's clustering methods to check this important. To evaluate the quality of the environment and determine optimal sites for the development the new cities in Tehran province in 3 pm base (man-made environment, social environment, economic environment and the natural environment) with a total of 22 indexes are used. The analysis and processing of indices for the paper two environments Matlab2013 and Arc GIS software was done. The results of clustering using FCM and overlay in the form of maps showing which areas are suitable for urban development in the East and South of Tehran. Also the plan was prepared by K-means that we can be used to provide strategies and integrated management areas.

The topic of land and how to use it have always been the main topic of the urban planning and the space-place assessment and organizing of the efficient and urban performances is one of the most important and most effective axis urban Sustainable Development. The aim of the performance of this reseach is the quality and quantity assessment of the urban land use with constant Sustainable Development in Piranshahr. The manner of this research is analytic descriptive. To this purpose, there indicators of capacity compatibility and social justice have been used to achieve the sustainable development. In the first stage, it is paid to the quantitative assessment of existing uses and capacity index analysis, in the second stage it is paid to the qualitative assessment of use in view point of compatibility by using compatibility matrix and analysis of social justice index with the model of the nearest neighbor and swot model. The results of the quality and quantity analysis show that often efficient face with lack. This lack equals with 175.5 hectar. Also the most extent of Inconsistency is in the Usage Industry, Administrative, Residential and educational. This situation is expressive of the lack of the balance and disharmonious between the efficient that was caused by the urban planners lack enough attention. So it is essential to fit the environmental balance and economic and cultural of the urban Sustainable Development in the planning process.
