Aim of this study is to identify suitable Urban Development spots with application of Environmental Criteria in Mahmoodabad Township. A series of criteria were identified by investigating various sources about the location of urban development to achieve the aim of this study. Then criteria were selected by Delphi questionnaire or survey experts. So 12 criteria and 30 subcriteria were selected for urban development site selection in Mahmoodabad Township. These remained criteria which can convert to maps were weighted with AHP method. Then criteria were converted to maps by Arc GIS software. After that the maps combined with a weighted linear combination by Arc GIS software and appropriate spots for urban development were chosen. Area of the biggest spot is 0/7 square kilometers and area of the next spot is 0/4 square kilometers. According to 26th article of executive regulations for new towns building, minimum area of a new city is 3 square kilometers. So, none of the spots are suitable for urban development. Results and the criteria which obtained in this research can be used as a guide in areas that have similar features (north coastal area of country) to Mahmoodabad Township.

2012
Kowkabi, Lila | Ghadiri Masum, Mojtaba
Industrialization and Urban sprawl together with population growth and increases in water consumption cause water pollution and destruction of natural resources quality; these are followed by reducing access to available resources such as drinking water. Every year a significant amount of urban waste water is discharged to water resources, while natural treatment is impossible. Cities in each level require different facilities and infrastructure. optimal resource utilization with appropriate site selection for water & wastewater facilities have an important role in water quality in the major cities and can control water pollution, so it has been considered to increase the quality of life in cities, also the neglect of attention to climate condition such as morphology, hydrology and topography cause negative impacts on urban environment. There are different models and methods to select suitable sites for facilities. They are specifically important in arid land where water resources have become increasingly scarce. One of the methods is zoning. In this paper satellite images have been used to locate facilities in a typical arid city in Iran, Shiraz. The large-scaled (landscape scale) land use maps has been prepared for Shiraz-Neiriz water basin, and the distinctive zones were determined base on arid and semi arid geo-hydro morphology. Then each zone were analyzed using large-scale land use, soil and topographic factors to determine adequate potential sites for facilities by regarding sustainable development and considering the cumulative effects of upstream area. At the end, some suggestions were determined to reduce urban environment pollution.

Increasing technology and population in the two recent decades have led to destructing nature and changing its land cover. Remote sensing is one of those new technologies which provide accessibility for managing earth resources. the dynamic information of remote sensing can play an effective role for monitoring and analysis of land use change using digital change detection techniques. Method used for the rate of development of remote sensing, is on the basis geometric correction, spatial and spectral enhancement of available satellite images with regard to the maximum likelihood supervised classification and post classification method. At first we produced land use maps by using the satellite images of landsat. The results of this study are, in addition to the impacts of environmental sensitivity visualization development trend based on the visual display, calculate of the land use changes together in developed area and production of digital map changes, to support land management.
