The present study aimed to assess the conformity of Mehr housing projects byInfill development pattern to answer this question: What is the relationship betweenMehr housing project in the city of Mahabad with Infill development and with itsspatial conditions of the city. The research method in present study in terms ofnature is "descriptive – survey" and in terms of purpose "applied" and in terms ofcollecting data is " field". Statistical society is the whole members of Mahabad Mehrhousing that were determined 361 persons as sample by Cochran formula. To dataanalysis was used the methods of descriptive statistics (frequency, percentage, mean, standard deviation) and inferential statistics (one-sample t-test). The results showthat Mehr housing policies in the city of Mahabad not comply with its physicalconditions. T-test results in this study showed that Infill development due to the useof the maximum of capacity available space of city, Can be considered as a suitablemodel and as the basis to guide Mehr housing policy in the city of Mahabad. Theresults of T-test about the physical factors (t=-1/48; p-value>0/05), socio-culturalfactors (t=24/35; p-value≤ 0/05), economic factors (t=13/27; p-value≤ 0/05) andenvironmental factors (t=27/29; p-value≤ 0/05) shows that Mehr housing policies inthe city of Mahabad comply with socio-cultural factors, economic factors andenvironmental factors but not comply with its physical conditions.

In this study is simulation of role of topography in thickness and Inlandpenetration of sea-breeze in southern coast of the Caspian Sea. The RegCM4as a regional scale climate model coupled with a lake model and also thereanalysis data of NCEP / NCAR used to determine of the initial conditionsof the model. The model was run during the peak of sea breeze on thesouthern coast of the Caspian Sea (July 2002) in both conditions (withmountains) and (without mountains). the outputs indicated that in withouttopography condition depth of the sea breeze will increase to the currentposition the southern slopes of the Alborz Mountains ( latitude ᵒ 35 ) but theland breeze in the area is gone. The maximum speed and changes in winddirection observed on the coast southeast and central Alborz respectively. Inaddition with non-topography conditions, the thickness of sea breeze indifferent areas significantly has increased with the highest rate on the easterncoast (longitude ᵒ 53).

In this study, by using the Mann-Kendall nonparametric method and Sen' sEstimator slope test, the trend of some elements including precipitation, average of maximum and minimum temperature and the number of snowydays Chaharmahal and Bakhtiari Province covers part of Zagros andZardkohe-Bakhtiari highlands, from which three major rivers includingZayandehrud, Dez and Karun originate. in an annual and monthly scale, wasevaluated in the stations of the province during a period of 30 years (1986-2015). The output was presented in the form of tables, graphs and iso-trendmaps as drawn in the Arc_GIS. The results showed that although changes inrainfall did not follow any specific trend in most months of the year, theamount of precipitation in the stations of Koohrang as the rainiest station inthe Province, Lordegan and Yan-Cheshme had a decreasing trend at thesignificance level of 99%; also, the the number of snowy days during Marchshowed a decreasing trend in Koohrang station. However, the averageminimum and maximum temperature in most areas of the province, in bothmonthly and yearly scales, except for the months of November andDecember, had a significantly increasing trend.

Rapid urban development in social, economical, cultural, political and environmental aspects, has affected the human life in recent decades. Introducing the sustainable development as the main theme of the third millennium is the result of urban impact on the biosphere and the range of different aspects of human life too. Concentration on differences in dimensions and indicators of sustainable development in one place and having them compared to other places can use fal for planners to realize the development potential and weaknesses. In theme lines, Boroujerd city have been studied as one of the median cities in the West of Iran to assess the indicators of sustainable development. The purpose of this study is to assess indicators of sustainable urban development in Boroujerd town, compared with Iran urban centers. In this study, methodology, is cognitive in terms of objective, and is comparative-analytical in term of identity and the data collection method is documental studies. To assess the level of development, the concept of sustainable development was classified in four dimensions: social, economical, environmental, physical-institutional and 44 indicators were identified. The data were collected in the Boroujerd city and Iran urban centers. Data were analyzed with sign test in SPSS software. The result has shown that there is no difference between Boroujerd city and Iran urban centers in terms of social and physical-institutional indicators. But, economic and environmental indicators have significant differences. The economic condition is not good but the environmental condition is better. On the other hand, taking into account all indices, the sustainability of Borujerd city, almost is same with Iran situation sustainable.

The KabirKooh landslide was studied as one of the immediate catastrophicevents which causes falling rocks from the KabirKooh hillside and theobstruction of the Seymarreh river course and also formed a lot ofgeomorphological shapes in this area. This landslide was located at 5 km ofthe Poldokhtar city at the south between the Ilam and Lorestan province. Themain purpose of this research to provide and analyzie of Morphometricfeature of the landslide inclusive, width of the rupture surface (Wr ), length ofthe displaced mass ( Ld ), length of the rupturesurface(Lr ), width of thedisplaced mass (W d ), the depth of the rupture surface (Dr ), the depth of thedisplaced mass to it will be discussed ( Dd ), (Dr /W r ), ( Lr / Dr ), ( Lr /W r ) andvolume. For this work by using by using Global mapper11 software, to beconform the topographic area maps in the scale of 1/50000 and the digitalelevation model. Arc Gis 9. 3 and Surfer 10 software was used for preparingand producing new data and information. Considering the analyse of thisindexs is, W r: equal to 15/5 Km, L d: 16/06 Km, Wd: 15. 5 Km, Dr: 300M, Dd: 300 M, Lr /W r: 0. 50, Dr /W r: 51. 67, Lr / Dr: 26. 03 and volume3908200970 m3.

The objective study was to investigate the effects of social capital onsustainability security in the villages the border areas. Statistical populationincluding the villages of the central city of Saravan are heads of households(N= 9946). 421 households (23 villages) using Cochran formula and simplerandom sampling were selected. For the analysis data, descriptive andinferential statistics two methods (single sample t test, Pearson correlationand path analysis) are used. Results the research findings on the impact ofsocial capital in rural sustainable security shows that the greatest impact isrelated to social security. Memorizing of patterns such a way that increaseslanguage, preservation of culture and religion, reducing drug use amongyouth, reduce the amount of conflict is between the people and so on. thelowest impact related to later economy. findings also show that dimensionpolitico-military security partnership, trust and of cohesion between peoplesand cooperation between police forces and and border guard to increase thepolitical participation of the people, ethnic and sectarian narrow the gap, reducing illegal traffic in neighboring countries, increased cooperation withmilitary forces in the fight against bandits and smugglers and maintainsecurity and order is sent.

Drought phenomenon with different goals including planning, watersources management and dealing with the problems due to water shortagehas been investigated by most scholars. This research examined therelationship between drought and the normalized difference vegetationindex (NDVI) in Ghrveh and Dehgolan region in Kurdistan, Iran. Todetermine years with meteorological drought, index of Standard Z duringa 20 year period time (1387-1368) has been applied. The results of thestatistical data in Ghorveh station in 2008 with total annual rainfall of 155mm and Z index of-2. 31, in 2000 with total rainfall of 253. 1 and Z indexof-1. 5 and in 2001 with 239. 5 rainfall and Z index of-1. 22. Weredetermined as drought indices. MODIS satellite images were used toassess the ecological drought. Associated with each image to a randomlyselected sample of 500 places in the software ERDAS, NDVI values werecalculated for these images. satellite image processing results andNormalized Difference Vegetation Index (NDVI) indicates a low indexvalues in the years 2000, 2001 and 2008 Were determined as ecologicaldrought years of 2001 samples had the lowest NDVI and central parts ofthe area under irrigation has almost lost its vegetation.

The above research evaluates the access and use of rural services ofthe villages in the province of Gilan, as examples of reducinginequalities and increasing the development. The method used in thisarticle is applicable in terms of target, and cross-sectional in tems ofidentity. To do this research, morris model, indexing method, standardization and dividing by average are used. After comparing thevillages of the province in terms of rural services, the obtainedoutcome indicates that accomplished results and ranking are in highagreement, so that in all models, villages of Saravan, Kelishami andGol Sefid have the most access to facilities and services and mountainvillages of Talesh, Shuil and Eshkevar Olia are the most deprivedvillages in rural facilities and services, respectively. Based on studiedindicators, the distance between deprived and wealthy villagesflactuates from 2 to 10 times. This situation reflects the gross spatialinequality of having advantage of facilities and services in the villagesof province Gilan.
