Abstract Management of towns as wide organizations through local communities can be interpreted as a means of both mutual interactions and the effect of physical structure on individuals. In order to achieve sustainable urban development which is based on consultative management of developmental plans, an appropriate capacity needs to be built. Capacity building in urban neighborhoods can be conducted through understanding citizens' abilities and engaging them in urban plans. The communication between the citizens and urban governors plays the most important role in sustainable formation of urban neighborhoods, management of optimal quality of life, conditions of residential neighborhoods, and sustainable urban development. The aim of the present study was to investigate the effect of consultative management performance on physical sustainability of urban neighborhoods. Survey method was utilized to collect data. In so doing, a "structured questionnaire" that was designed based on internal and external sustainability indicators was applied. The target population included four main neighborhoods of Piranshahr. A sample of 382 individuals was selected through Cochrans' model. Statistical tests were conducted to check the sustainability of every single indicator. Then, the urban neighborhoods were ranked based on Vikor model. Finally, the results showed that the target indicators had a significant effect on the sustainability increase of the urban neighborhoods such that the people's participation affected neighborhoods sustainability in the town. Finally, based on Vikor model the results showed that neighborhood 2 with a sustainability rate of Q=0.55 had more favorable conditions compared to the other neighborhoods.

Landslide is one of the natural hazards which affects mountainous areas and destroys residential areas, farms and basic facilities each year. In addition to the damages caused by landslides on roads in towns and villages, the natural environments are also affected by soil erosion. The study area with an area of about 80,000ha is located in the west of Khoy city, northwest of Iran. Some landslides have occurred on the southern slopes which verge on the roads and frequently damage the main road, Iran-Turkey railway and several villages, such as Gougerd and upper Kalt village. Due to the proximity of the study area to the main roads and residential areas and the existence of several historical mass slides, evaluation of landslide hazard and preparing a risk map is necessary. In this research, the potential landslide zoning map was developed by evaluation of each parameter influencing landslide including lithology, slope geometry, geological structures, relative elevation, land use and coverage and ground-water. Final zoning map was produced through overlaying of the maps developed by scoring of the mentioned parameters. The study area was divided in to 5 zones from potential landslide view of point, including safe, low, medium, risk and very high risk zones. About 23 and 5.6 percent of the total area are subjected to high risk and very high risk landslide hazards, respectively.

Environmental protection in rural areas is of the necessities in rural development. One of the important issues in rural areas is to find the appropriate landfill site. In this article, in order to assess the proper places for landfill in Lighvan village, corresponding geomorphological factors are provided and analyzed. In evaluating landfill site, GIS software and network analysis process modeling (ANP) are used. Five human-economic key factors of topographicalmorphology, climate-hydrology, soil-vegetation and geology are considered. These factors produce 12 layers of land use, distance from residential areas, and distance from the lines of communication, distance from fault, distance from the river, slope, elevation classes, and direction of slope, climate, soil, vegetation and the lithology. The appropriate landfill site is identified by using the layers and models in Arc Map. Results show that proper places allocate 23.87 and improper places allocate 21.13 percentage of the desired area. By zoning plan, appropriate places in the entire Lighvan village are introduced which can be used in future planning.

The evaluation of environmental conditions in particular climatic conditions of crops such as soybean that have a great economic importance for the country. In this regard, climate regions, with a minimum requirement of soybean cultivation were identified. By choosing a 20-year period from 1989 to 2008 and precipitation map of Iran on the basis of all available stations over 20 years of daily data completed, three regions with annual rainfall of over 500 mm in the North, West and South West were then determined. To increase precision, creating a virtual stations on the basis of daily maximum and minimum temperatures, areas outside of the internal parts were removed and each of the relevant area, was approved to determine the ultimate potential. Using CGMS software, the minimum temperature, maximum vapor pressure, sunshine hours and wind were estimated for rainfall estimation from Completely Regularized Spline (CRS) method, and Spline Regularize (SR) method was used to estimate relative humidity. In the next phase, the mean rate of deficit in soybean yield in dry land conditions was determined using the CROPWAT. Then, three valuable layers of precipitation, relative humidity and maximum temperature were explained by the use of AHP to determine the weight of each layer which was overlapped. The results showed that in the West and South West regions, with the percentage deficit crop yield of over 50%, conditions are low to moderate but the western half of the country's northern region can be considered suitable for soybean cultivation. Calculations showed that the deficit efficiency of the crop in this region, was less than 10 percent and thus has good potential for rain-fed soybean cultivation. It also became clear that to start rain-fed soybean cultivation in all regions, the month of Ordibehesht was more suitable than other months.

One of the most important procedures in the water sources studies is the estimation of the local distribution of precipitation in different time scales. The study of precipitation is a basic element in the water balance studies and is an important factor in the natural sources programs of each country. Also, because of the rain-evaluation stations deficiency and their discreteness, it is necessary to use a special model. Besides the interpolation of precipitation amounts of stations, this model should interpolate topography, moisture and the slope direction of precipitation. In this work, at first, some data were gathered, in one year. These data were connected with the precipitation and moisture of 9 synoptic stations and 31 rainevaluation stations. These stations were located in the Lorestan province. Second, using the least square method and with the help of Maple software, the relations between precipitation and moisture was extracted. Third, by using the Python programming language, these relations were linked into the GIS. Finally, by so doing, the digital precipitation modal was achieved. The results obtained from the digital precipitation model show that, the precipitation amounts are different from the measured data in the stations, from 0.02 to 11.6 mm. Also, to investigate the efficiency of the considered model, the data obtained from this model were compared with the precipitation data achieved from TRMM radar at 21 April 2010. The concluded result show that, the determination coefficients are 79 and 86% for the TRMM data and for the digital precipitation model, respectively

The research methodology of "descriptive-analytic" with the aim of analyzing the indicators in the assessment of urban development in the catchment Ghaffar has been carried out in area. Indicators of urban development in the area according to available data resources include 12 factors of topography, vegetation, slope gradient, the land, soil conditions, altitude, power user, the communication area, the hydrology of the region, the economic and social area, region, land use and fault conditions which are classified. To form database and providing required layers of base map we used data on natural resources of Khuzestan. To achieve the status of urban development in Ghaffar catchment conversion layer and software were produced in Arc GIS 10. According to the fuzzy membership functions of the fuzzy map conversion and in order to analyze their situation and assess the model of urban development we offered Ghaffar catchment area a fuzzy gamma operator (Fuzzy Gama). Maps produced in the ArcGIS software and fuzzy process and analysis layers show that among selected indicators about 0.67 of the basin area is not suitable for urban development. Test threshold of 0.7, 0.8 and 0.9 for gamma analysis shows that, Gamma analysis phase with a threshold of 0.7 in accordance with the conditions of the region and consistent with than the limited parts of southeast and east bordering of the catchment areas of basin for urban development is not appropriate.

The NCP as one of the effective teleconnection patterns in level of 500 hpa have an important role in thermal and hydro-climatic variability in East Mediterranean region. In this study to investigate the correlation between the NCP and maximum temperature fluctuations Iran for a 60 years period (1950-2010) have been studied. Pearson correlation analysis as the main method used in this study show an inverse relationship between maximum temperatures and selected stations and NCP index. This shows decrease of temperature in positive phase of the NCP and rise of temperature in negative phase. In terms of time correlation coefficients were calculated and showed a significant negative correlation between the temperature of stations and the NCP in months of January, February, March and almost direct relation most stations in August. At monthly interval in the monthly correlation between stations with 0.342 were computed in January. Seasonal correlation of shows a significant correlation of maximum temperatures in winter to be -0.212. In terms of period, the results indicate a strong correlation between cold period in most stations and mentioned index. Atmospheric circulation in 500 hpa at positive and negative phases showed in positive phase, settlement of deep trough on the Caspian Sea, Iraq, Turkey and Iran, and also the location of Iran in the eastern part of the trough axis on the other hand, indicates establishment of a ridge on the North Sea and Europe which leads to transfer of cold temperatures of northern Europe and its adjacence of polar section to Iran. But on the negative phase placement of Iran beneath the ridge axis leads to the creation of a barotropic atmosphere with weak zonal wind and warm temperatures to Iran. So with blowing warm air from Africa, Arabia and low latitude Iran's temperature rises.
