owledge of spatial rainfall behavior in environmental, land planning is effective. These changes in the later place in the form of time later and in the climate of the area. The Target of this study was to reveal the presence or absence of precipitation trend in the ratio of the height of local precipitation behavior and identify province mazandarn. Therefore, the purpose of the rainfall data station 32 (Meteorological Agency and Department of energy), the statistical period 1988-2010. To get the regression analysis of precipitation process was used to identify the local behavior of precipitation, the method of spatial statistics were used. The results obtained from the behavior of precipitation, the existence of the process within the scope of the study and the emphasis is most consistent with the Be modified regression model at adjustment indicate. According to the regional behavior of precipitation, using local spatial statistics, spatial Moran well hot spots check this behavior. The results showed that precipitation in the province of Mazandaran has the pattern of clusters with high value. According to the local hot spots and methods Moran, West Coast up to a height of 700 m has positive z score and clusters with high value, 99% confidence level. This range includes 15% of the total of the province. The range of the Southern Highlands as well as the negative z score and clusters with low value with a confidence level shows 99%. This range is also about 20 per cent of the province's total. About 65 percent of the total area of the province as well as the lack of a significant trend show.

The karst areas refers to individual areas that shaped by the dissolution of bedrock and subsurface drainage grid development and are connected mainly with limestone. The karstic formations outcrop 20 percent of the land surface of the planet is covered that 11 percent of Iran are part of this 20% is included. The ZAGROS region of origin karstic formations in the country that the formation of karst forms and numerous caves in the area attest to this claim. Overall creation and development of karst geomorphology, the formation of karstic aquifers are karstic systems. In fact karstic aquifers, underground reservoirs that store water in a web of interlocking joints and cracks, caves and canals. The karst can be effective ways to develop into three categories: physical, chemical and hydrogeologic studies divided that role of lithology and its properties, weather conditions and hydrological and structural factors such as faults and fissures, and slope area are of particular importance. In this study, characteristics OSHTORANKUH region of karst processes and the formation of karstic aquifers were examined and to do so using the AHP model the effect of weight each criterion was determined in karst area. Then, using the SAW model )is a subset of multiple criteria decision-making methods( Zoning areas prone to karstic aquifers OSHTORANKUH software was Arc GIS 10.3 and defining the center of the southern slopes of the western and north-eastern slopes of the mountain that are consistent with carbonate formation, the intersection of active faults and are the focus of surface runoff ,it also has a gentle slope than other parts of the region, have Better and more suitable conditions for the formation of karst processes karstic aquifers. The adaptation of the area most prone to the aquifer karst springs evidence of the correct zoning of the area is karstic aquifers.

The heat waves today are one of the most important climatic hazards in the world. According to many scientists, the Severe and frequent occurrence of heat waves in recent years has been due to the emission of greenhouse gases and consequent increased global warming. The purpose of this study is to investigate changes in the frequency and intensity of heat waves As well as their relationship with Global land-ocean temperature anomalies and greenhouse gases in the north-west of Iran. At First, maximum temperature of two meters of the surface during the period from 1851 to 2014 for 164 years was obtained from NASA’s website, then the maps of heat waves was drawn and extracted. Then, we analyzed and evaluated the frequency and severity of the heat waves, as well as changes in the annual, decade, fifty years old fluctuations and their centenary were analyzed. To achieve the research objectives, Pearson and Spearman correlation methods, linear and polynomial regression and non-parametric Mann-Kendall test were used. The results showed that the frequency of occurrence of heat waves in the considered period interval is incremental and relevant, and the most frequency of occurrence was in decades. Also the intensity of the heat waves is associated with a relatively significant increase, and the most intense heat waves occurred in the decades of the late 20th and early 21st century until the present period. The results of the correlation coefficients indicated that the intensity and frequency of the heat wave incidence have a positive and significant correlation with the Global land-ocean temperature anomalies. The results of investigating the relationship between frequency and intensity of heat waves with 4 important greenhouse gases, including: (CO2, CH4, N2O, SF6), showed that, except for the positive and significant correlation of carbon dioxide gas with the most severe heat waves in June, There was no meaningful relationship between them. The results of the Mann-Kendall test indicate an incremental and significant increase in the frequency and intensity of heat wave events in the North-West region of Iran.

Studies show that 14 provinces are impacted by wind erosion and the movement of sand dunes. The sand originated from the shores of Oman Sea is the most important environmental hazards that threaten the already large number of rural settlements. Sands of marine origin are available on the beach and away from the sea of dunes in addition of marine origin, Predictive models for planning sustainable use of land use and land cover in a country like Iran that land use is changing rapidly, there is an urgent need; To detect and predict changes in land cover changes overview to better manage natural resources and protect marginal lands beaches and is very effective long-term policy measures. The aim of this paper is modeling and prediction of changes in land-use in 2035 by using CA Markov model and Landsat satellite images in the West of Zarabad,( The coasts of Makran). Then to determine the changes in the movement of sand dunes in the study area ranged from twenty-three years (1991-2014), satellite imageries from Landsat 7 and 8(ETM+ sensor) with 15 and 30 meters spatial resolution , was used. The 1991, 2001and 2014 month August images were used, this images from website of the US Geological Survey (USGS) have been prepared. Finally, these images by using Geographic Information System (GIS), ENVI and IDRISI softwares were analyzed. The results showed that the changes in the region the largest increase in the interest of sand dunes in the year 1991 (25.561) km², in 2001 (10 . 568) km², and in 2014 (45.578), and the increase of (17.198) km², has experienced. The results also estimated that in future (2035) sand dunes area increase to 592.45 km².This increase in area of sand dunes occur in the absence of proper and efficient management is done in order to stabilize the sand. This increase resulted from changed moorland 162 km²of land area (27%) and 12 kilometers of vegetation (2%) and 23 km² of fluvial (3.4%). These changes makes heavily exposed about 6 villages (Karti,Gnjk, Sohroki, Pyvshk, Vanak and Kalirak) to the movement of running sands.

One of the Challenging problems of Tehran metropolitan region is Air pollution. Suburban expansion in the form of sprawl patterns have created the travels and transportations, due to the dependence on personal vehicles contributes more than 85 percent of creators of air pollution. The article studied the role of transportation in emergence of urban air pollution in Tehran metropolitan region, have population more than 15. 98 million. The method of this paper is of analytical and is based on the secondary data and traditions of the Quantitative research methodology. This article have been wrote in the context of Retroductive strategy and meta-analysis method and compositional research traditions. For analysis of suburban spatial transportation have used Raw Data Intra-Urban and suburban Data in 1395 Year And for spatial analysis of air pollution (PM2. 5 and PM10), have been used The raw data from sensing stations and Landsat satellite images (OLI) for three selected days in 1392, 1393, and 1395 as survey samples in the ArcGIS software. The research findings indicate that due to the intensity of transportation flows in Tehran metropolitan, the suburb to the suburb, the suburb to the central city (Tehran) and vice versa, Air pollution center Rise cannot be attributed to Tehran alone, as the area of pollutant sources has been distributed within the "Tehran metropolitan region ". So, the amount of spatial correlation between air pollution maps and transportation flow maps in selected days (2 Bahman 1392, 5 Bahman 1393 and Dec. 7, 1395), in all cases indicated high spatial relations (more than 75%), Confirmation the idea of this paper. Analysis of this situation in triple loops also shows that the highest volume of transportation is in the city of Tehran (CBD), suburban and exurban areas, respectively and the distribution pattern and spatial accumulation of pollution are also subject to this situation.

In this research, applied synoptic model for determining the average daily temperature and its relationship with the Geopotential Height in middle level (500 HPa). Therefore, two database were used: database of atmospheric circulations, includes the data of geopotential height at 500 HPa and its data were extracted from the NCEP/DOE(US National Oceanic and Atmospheric Administration) in hours 00: 00; 03: 00; 06: 00; 09: 00; 12: 00; 15: 00; 18: 00; and 21: 00 in Zulu and other, database of environmental (surface) events. Contain of average daily temperature in the Mashhad, Torbat-Heydarieh and Sabzevar stations in Khorasan Razavi Province. The maximum and minimum of these stations in the time interval from 01/01/1987 to 01/01/2014 equal as 9862 days from the meteorological organization of Iran. Then, was calculated the correlation of the average daily temperature of selected stations with high atmospheric data (500 HPa level) with the northern hemisphere in Surfer Software. The result shown, four regions in the northern hemisphere which had high correlations with selected stations. The correlation results suggest that the United States has 25 pixels, Northern China 25 pixels, Africa 45 pixels and Japan with 65 pixels. Then, weighted average of pixels in heights by multiple regression equation station. The results of diagnostic models indicate that, per geopotential height increase in the profile, the average daily temperatures of selected stations in the Sabzevar 1. 4, Torbat-Heydarieh 1. 3 and Mashhad 1. 3 degrees Celsius will increase.

The term urban heat island (UHI), described the phenomenon of climate change in urban areas compared with surrounding rural areas. UHI effects include: increasing in energy and water consumption, air pollution expansion and interfering in thermal comfort. Surface urban heat island (SUHI) contains patterns of land surface temperature (LST) in urban areas that has interaction with UHI in urban canopy layer and urban boundary layer and investigate with thermal remote sensing. SUHI has diurnal and seasonal variations so requires multi-temporal data to analysis SUHI. In this study, the multi-temporal MODIS (Aqua and Terra) data product were used to analyze the SUHI in day and night in Tehran metropolitan. Physical and biophysical surface properties such as: land cover/land use (LULC), elevation, albedo, vegetation index (NDVI) and impervious surfaces index (NDBI) were used to interpretation of the LST and SUHI changes. The results showed that SUHI in Tehran, has spatial-temporal diurnal and seasonal variation. So that during warm days the surface urban cool island (SUCL) is formed in Tehran. At night times, SUHI index values was different between 2 and 5 ° C (maximum in the spring). The results also showed that different of land cover thermal properties, albedo and elevation was the most important factors is the diurnal changes of SUHI while phonological changes of vegetation and albedo, was the most important factors in seasonal changes of SUHI.

Vulnerability assessment and mapping of hazard pollution is raised on as an important management strategy to protect the karst. Karstic aquifers in semi-arid regions of the West of Iran with regard to the natural conditions of the region, are susceptible to contamination. Estimation of amount and vulnerability mapping of aquifers in the karst religion of Bistoun-Paraw – Kermanshah plain against poullution emissions using the COP model are theaims of this study. This model using of three parameters-covering layer (O), concentration of flow (C) and regime of precipitation (P)-assesses the vulnerability of karst water resources against pollution. The results show that %31/4of the area has located in the zone of average vulnerability and %30/7of area has been in the low vulnerability area and %37/9of the area has taken a very low vulnerabilities value. The later zone has been included most part of the plain. Major areas of low and moderate vulnerabilityzones has been located in the high part of the area on wherethe developed limestone territory of karst formations is found. Vegetation cover of these regions areforest-steppe vegetation where is located in the low vulnerability zone and without vegetation cover where is in the moderate vulnerability zones. The latest has over 800 mm Precipitation. Totally, the Parameters that have most important role in vulnerability level in the areaare C, P and O respectively.

The cognition of cropping pattern is important for planning and resource management. Remote sensing as a science and technology of spatial information and geographic information system due to having the analytical facilities can play a key role in determining the distribution of crops and their lands under cultivation. In this research, in order to identify and separate the lands under cultivation of the dominant crops in Lenjanat of Isfahan province, the multi-temporal images of Landsat 8 satellite, OLI sensor were used in the dates of April 17, July 6, and August 23 in 2016. Using maximum likelihood classification and normalized difference vegetation index (NDVI) of the agriculture crops in different periods of growth and according to their cropping calendar, the map of the cropping pattern of the area was determined. To evaluate the accuracy of the results, the produced maps were examined with reference data. Kappa coefficient and overall accuracy were 0. 88 and 90%, respectively, in maximum likelihood classification, and 0. 90 and 93%, respectively, in NDVI. Furthermore, statistics presented by Agricultural Jihad Organization of Isfahan province in the 2015-2016 crop year was used for evaluation. The results showed that there were differences equal to 10. 2%, 18. 6% and 1. 8%, in the area under cultivation of wheat and barley, rice, and potato and forage, respectively, in maximum likelihood classification, comparing with the statistics of Agriculture Jihad while the results of NDVI comparing with Jihad statistics showed the errors equal to 6. 6 %, 6. 5 % and 3. 2%, respectively, that indicated the better performance of temporal vegetation indices in estimation of area under cultivation according to its phenology. Investigation of land use and cropping pattern of this area indicate a high centralization of agricultural lands with high water requirements and industries on the proximity of Zayanderud River which necessitates the spatial analysis of land use in this area.

Solid waste is an integral part of human life, generation of various quantities and qualities of which is one of the greatest environmental problems of the current era. Application of modern tools and technology to find the right place for recycling, where the volume of recyclable materials can be reduced, seems vital for reusing the recoverable materials contained in normal waste and their recycling and reusing in the cycle of industry. The study aimed to find a location for recycling and its converting industries in Kelardasht, Iran. This was a descriptive and analytical research with a survey approach. At first, experts of the field were recognized and a scientific panel was formed to identify the relevant criteria through Delphi method. In this respect, five criteria of the distance from residential and commercial areas, the distance from urban streets, the distance from the river, the distance from the hospital and education centers, and the distance from hotels, banks, and offices were selected. After that, the permitted distances for these criteria were determined by Delphi technique, followed by the application of the centroid method to determine the exact distances. Moreover, the analytical hierarchy process (AHP) and geographic information system (GIS) were exploited to determine the and use weights in raster maps and generation of the zoning map. Furthermore, the best locations for recycling were selected in Kelardasht using field survey method and based on the zoning map. According to the results, four sites were selected for recycling of recoverable solid waste in this region

From the late twentieth century, human kind has found out that if he wants to obtain cost efficiently and continuous utilization of lands, it is better to execute this in a planned framework named management plan. Such idea is became as an introduction to monitor the land or utilization of lands. Monitoring lands means contribution of an optimized space for land utilization with realization of common upcoming and related to each other in the past, now and in the future. Therefore, the objective of this research is to select the suitable lands with monitoring lands of view in the city of Hamedan using a Multi-Objective Land Allocation method. The aim of Multi-Objective Land Allocation method use is to contribute selection of proper lands with monitoring approach based on ideal levels concept which have been executed by 3 different ecologic, socio-economic and strategic aspects existing in the territory. The examined use include agricultural use (water system or dry farming), pasturing use and urban use which based on the highest weight of independent variables, the area has been allocated to mentioned use with land monitoring approach. In what follows, the land suitability map is obtained through MCE operation for each type of land use and the obtained land suitability areas were calculated using these maps for which the results are as follows: irrigated agriculture with 601. 176 hectares, dryland farming with 961. 193 hectares, urban suitability with 762. 984, and rangeland management suitability with 960. 552 hectares which is an important criterion for determining the area for implementing MOLA. In the next step, it was time for implementing MOLA module for resolving the contradictions among the uses. The results of MOLA showed that in average for the three studied aspects, the maximum area was associated with dryland farming with 364. 4 hectares which is equivalent to 32% of the studied uses and the maximum weight of 0. 4 was associated with irrigated agriculture. These resulted were obtained based on five factors (i. e. the current area of each land use, the favorable area for each land use based on MCE method, the occupational dependencies of different individuals to each land uses, prioritizing the ecological, economic, and social aspects of each land use). Finally, the results showed that selecting the suitable lands with spatial planning point of view using a Multi-Objective Land Allocation method is carried out properly through economic, social, and ecological aspects.

In evaluating and studying natural phenomena, we sometimes encounter certain seemingly independent forms and processes and phenomena that are related to each other and can be analyzed through a series of mathematical equations and correlations, but sometimes paired phenomena It is found that they have certain relations with each other, but these relationships can not be called correlation, but their relationship has caused them to be presented as a double (a type of conjugacy) and they would appear to be opposing reactions in terms of collocation. The tectonic changes, especially the neonate movements, and its effects and consequences on groundwater reserves of these types of reactions. The purpose of this study is to investigate causes of groundwater drops in the framework of geodetic theory. With regard to the fact that in recent years, the water level in the northern plain of Mangasani has fallen sharply. Undoubtedly, non-structural activities in the region, along with other influential factors (uncontrolled harvesting of groundwater resources, droughts, etc. ), can be attributed to The title is one of the main causes of water loss in the region. For this purpose, with the aim of evaluating the tectonic activity of the area, some geomorphic indices such as basin shape index (BS), drainage asymmetry index (AF), inverse topographic symmetry (T), mountain front sinus index (J), hypersonic integral (Hi), Valley Depth Wide Index (VF), River Sinusity Index (S), Longitudinal River Gradient (SL), Relative Tactical Rating Index (Iat), and Hierarchical Anomalies Index (Δ a) have been used. The results show that the whole basin is dynamic in terms of tectonic activity. The tectonic situation in the range and the results of statistical data indicate a change in the level of groundwater table as a result of tectonic changes in the southern plain of Nur Abad, as evidenced by the fact that the depth of the station was 89 meters less than 82 meters The highest drop in the Khomeghar well is about 26 meters in the southern part of the basin, in line with Kazeroon's active fault.

Nowadays almost all big cities are confronting heavy traffic and suffering from lack of parking lots which leads in traffic jam. According to the significant role of vertical parking in reducing the traffic load and smoothing the traffic current; this study was carried out with the purpose of presenting a decision support system for vertical parking site selection for mechanical and constructive parking lots by using Fuzzy-DANP method. Each criterion’ s correspondent GIS data was acquired from Tehran Municipality for district no. 3, 6, 7, 10, 11 and 17 which were chosen according to the corresponding mayors’ opinions of those districts and converted into its specific layer. Each criterion’ s weigh was exerted to its determined GIS layer and eventually all those layers were integrated with each other. The final map of GIS output demonstrated a spectrum which determined the most appropriate to inappropriate locations to establish a parking of each type. The final results were shown within a user interface, including the GIS map and the estimated location of the chosen district and parking type. The overall steps mentioned above are forming the DSS of the study. The results showed that setting up mechanical parking in districts no. 3, 6 and 7 is proper. For building constructive parking; all districts are appropriate.
