Abstract
Study of land use/cover changes is widely used in environmental planning. During the last decade, growing increase of aridity in Uromiyah Basin has become a major regional and even national problem. The purpose of this study is to reveal the changes in land use/cover in the southern and southeastern parts of the basin with using 2 images for month of July of 2000 to 2017. Landsat TM and OLI data and NDVI were used for classification this study. Land use/cover maps in the two studied years were provided using Maximum Likelihood Classifier (MLC) algorithm applied on two series data including spectral bands (data series 1) also spectral bands and filter texture layer (data series 2) and six categories of land use/cover containing Irrigated Farmland, Dry Farmland, garden, rangeland, bare land and water bodies were distinguished.. The accuracy of the produced maps were assessed and compared with the training samples derived from Google Earth images and Kappa Index, overral accuracy, producer accuracy and user accuracy. The results demonstrated that the maps produced using the data series 1 have higher accuracy and the overall accuracy of the maps of 2000 and 2017 using the data series 2 are 98.93 and 98.29 and these values for data series 1 were gained 99.28 and 91.45, respectively. In additional, texture filtering decreased amount of mixing between classes of rangeland, Irrigated Farmland and garden. The results of change detection showed considerable increase in the area of Irrigated Farmland (13.44) and garden 1.85 (27.24) an also at the studied period, the area of the water bodies and rangeland were decreased to 1.58 and 22.94%.

Abstract
The emergence of a variety of inequalities, widespread poverty, malnutrition and ... were examples of the effects of urbanization. For this reason, many scholars and experts have focused on the quality of life, in order to improve living conditions and improve the quality of life of human beings. Many studies show that satisfaction with different dimensions and characteristics of the neighborhood affects residents' quality of life. Considering that satisfaction with life, i.e., the full satisfaction of all parts of life, if this kind of satisfaction does not develop among residents, more serious problems such as intra-urban migration, severe class contradictions and the problem of uplifting and down-town faces Accepts. Therefore, identifying the effective factors on residential satisfaction in each neighborhood, which is in accordance with the needs of the residents of that neighborhood, is one of the main goals of urban planners in order to increase residential satisfaction. The purpose of this study was to investigate the effect of location and quality of environment on improving citizens' satisfaction from neighborhoods. The research method was descriptive-analytic, data collection method, library and survey, sample size was estimated 315 by Cochran formula. In order to test the hypotheses presented in this study, structural equation modeling was used in Lisrel software environment. The results of this study indicate that spatial sense of belonging and quality of environment have a significant effect on residents' satisfaction with the neighborhood.

Abstract
The purpose of this study is to determine the long-term variations in rainfall data as well as to identify wet and dry periods of 35 synoptic stations in Iran. In order to know the variation of rainfall in studied stations, average maps, coefficient of variation and skewness were drawn. Then, using the Mann-Kendall test, the significance of the trend on each station was tested at 95% confidence level. Finally, wet and dry periods were identified by using 20% high and low extreme rainfall during the 50-year study period. The results show that the general model of the country's regime is that the rainfall levels from the north to the south-east and from the west to the east of the country are reduced. The lowest values of the coefficient of variation and skewness are related to the northern regions especially the Caspian seaside and the highest amounts are in the southern regions, especially in the south and south-east. In general, the results of the Mann-Kendall test show that rainfall data in the seasonal scale, with the exception of several synoptic stations, do not show a significant trend. Most wet periods occur in the spring and the lowest in summer and the highest dry periods occur in the autumn and the lowest in spring. The number of droughts in the cold periods is significant. Also, the frequency of occurrence of dry periods is more than wet periods.

Abstract
Following developments in urban contexts of contemporary Iran, the creation of new urban contexts and cities has a direct impact on the ecosystem of its surrounding area. Urban neighborhoods on the path to achieving the goal of sustainable urban development require the integration of architecture and the principles of environmental sustainability. Using the Sustainable Architecture approach based on the principles of world standard is one of the most effective steps in this field. Progressive research, combined with the LEED World Standard Code of Conduct as a basis for evaluation, has revised the classification of the indicators of this Code based on biological and indigenous characteristics in the Qom city. To this end, urban texture and neighborhood assessment metrics are explained in the LEED and then with the aim of determining the importance category, baseline indices at the scale of the study area - renovated settlements (Pardisan City) - in a manner Qualitative analysis has been investigated. Finally, quantification in each section of context indices is done based on existing statistical documentary data for accreditation sub-indicators and, according to the final findings, a new classification of baseline assessment indexes for contemporary urban context designs. Based on the degree of effectiveness provided.

Abstract
The innate sense of interaction with the region is a sign of environmental sensitivity, which is very vital in the 21st century. Today, it is inevitable that regionalism should be included in a larger discourse of architecture, and that the debate over the role of the use of regional green architecture as a factor in cultural identity and sense of place should be promoted. The present study argues that regionalist architecture has entered a new phase of its evolutionary process, which is sustainable regionalism. In this view, regions must be defined in terms of their unique resources and specific constraints. Instead of being influenced by globalization, regions must follow a complex interdependence in a global and regional interaction system that is physical, social, cultural, and most importantly ecological. Therefore, using the method of qualitative content analysis based on the logic of inductive reasoning, from the textual data and architectural experiences mentioned in the research, move and by extracting the hidden concepts in it, gradually reach more abstract levels of sustainable regionalism. We will find. In addition, using the latest works of architecture selected by international institutions and awards and competitions, we are developing examples of sustainable regionalism. Achieving a model or theoretical framework that demonstrates latent disciplines and repetitive patterns in regionalist architecture and sustainable architecture can be the culmination of research.

Abstract
This study was aimed at identification and determination the spatial variations of sediment yield in Qarasu watershed located in Ardebil province, NW Iran, considering the negative consequences of erosion and sediment yield. In this regard, the monthly time scale, as the basis of work, was used to prepare the sediment rating curves. Preparation of monthly sediment rating curves based on sample flow and corresponding sediment discharge data in 19 hydrometry stations at the watershed during 14 years (2002-2015). All of statistical analyses were done by SPSS statistical software. Also, presentation of spatial variations in sediment yield over the watershed were made possible through the capability of GIS. The results of regression relations between flow and sediment discharge showed a close and significant relationship on a monthly time scale. The regional generalization of these relations for the whole basin showed that the seasonal difference was evident and the highest and lowest coefficient of determination was allocated to May (R2 = 0.74) and August (R2 = 0.55), respectively. Also, the highest and lowest sediment transport was observed in spring and summer, respectively, indicating the type of rainfall-runoff regime dominated on Qarasu watershed. In terms of the annual sediment yield, Yamchi station with 3970 tons per year and Nanakaran station with 66 tons per year, have the highest and lowest sediment yield among 19 stations of Qarasu watershed, respectively. According to the high levels of sediment yield in the Balikhly and Khyav sub-watersheds, it was recommended that more attention be paid to protecting and strengthening the water and soil elements and reducing the driven forces of erosion and sediment production in these sub-watersheds.

Abstract
During the rainfall, the intensity of precipitation varies. Changes in the amount of precipitation during an event of rainfall are effective in the resulting of flood and its intensity. Knowledge of how rainfall changes over time during rainfall is determined by temporal distribution pattern of rainfall. For this purpose, availability of short-term time scales rainfalls data are important that obtained by rain gauge stations. However, the low density of the rain gauge network and the lack of sufficient data from the time pattern of rainfall have always been a problem in determining storm patterns for executive plans. Therefore, the simulation of WRF numerical weather models can be used. The WRF model is one of the most responsive models for predicting precipitation, temperature and atmospheric elements that used in this study. In this paper, three great storm events on 15 December 2003, 24 - 26 December 2006 and 6-7 March 2007 have been selected in the Parsian dam basin and surrounding areas in south west of Iran. The result of WRF numerical weather prediction model for these great storms compared with data loggers. It showed that the WRF model was able to performance the heavy rainfall and simulates the rainfall pattern in these dates.

Abstract
The Kan-Soleghan basin is located on the southern Hillside of the Alborz, which has affected the Alp-Himalayan active zone over time. In this respect, the evaluation of active tectonic processes and their effects on many human activities, such as the design and construction of cities, powerhouse, dams, and industrial facilities are of great importance. The passage of the Tehran-North Freeway Tunnel from the area increases the activity of the faults that contributed to the formation of the current morphology of the basin. In this research, morphotectonic indices including river asymmetry index (Af), basin shape (Bs), hypsometric integral (Hi), Stream length index (Sl), mountain front sinusity (Smf), valley width to valley height (Vf), topographic symmetry (Tp) was calculated. Finally, the mean of the results of the indices was calculated as the LAT index. In the present study, topographic Map 1:50000 and digital elevation (DEM) maps with 30 m spatial resolution (ASTER sensors), the boundary layer of the basin, were used to calculate morphometric indices. The Kan-Soleghan basin area is divided into three tectonic regions with slow, semi-active, active Tectonic, and the calculation of the relative active tectonic (LAT) index indicates that the studied area is in tectonic terms in active state. The tectonic structures, especially the faults of the region, have affected the asymmetry and shape of the basin. The main river Kan-Soleghan also shows asymmetry, which can be said due to the structural factors, especially the faults of the region, the basin has asymmetry and deviation to the left of the basin. Also, the construction of the Tehran-north freeway and the location of the Tunnel openings in the vicinity of the northern fault of Tehran, is one of the human factors influenced by the tectonic activity of the area, which requires tectonic activity.

Abstract
Agriculture in the context of climate arrives at a favorable outcome. One of the important goals in agricultural researches is the investigation of effects of atmospheric parameter on various agricultural products. In this research we study the thermal and phenological conditions of grape cultivation in Hamadan province. In this study we analyzed thermal conditions for grape based on minimum and maximum daily temperatures of Meteorological stations in Hamadan province, by use of thermal potential, normal distribution, optimal deviation, growing degree days (GDD), phenology interphase methods. We also used SMADA software for statistical analyses and by Arc GIS Software to determine the possibility of frost and IDW technique for zoning and presentation of spatial distribution results. The results show that from the southern to the northern of Hamadan province the total heat units is reduced. An examination of the probability of a late spring frost at 95% showed that the date varies from late April in the southern regions of the province to the first decade of May in the northern half of the region. The probable date of late spring frost was seen at the end of April in the southern half (Malayer and Nahavand) areas, which coincides with the phenological stage of germination. The date of these phenological stages complete with a delay of ten days from south to north. The deviation from optimal temperature conditions in each grape phenological stage, in the northern half is more than that of the southern half.
According to the research results, early varieties of grapes is suitable for cultivation in the northern half of the region, due to the lower heat potential.[D1]

Abstract
Considering important role of housing in contemporary urban areas, evaluating urban housing quality has become one of the most popular topics in recent researches. Housing has vast conceptual perspectives which include many aspects of urban life beside the dwelling purpose of it, such as recreation, primary schools, and play yards and so on. The most efficient tool for achieving such purposes is evaluation of qualitative and quantitative urban housing indicators. Using quantitative, objectivistic, positivistic methods and models frequently observes in Iranian scientific journals recently. This article aims to study and evaluate such researches, using scientific analytic methods which have accepted and published in domestic scientific journals. The emphasis of this article is to review papers which studied urban indicators in any area in Iranian urban areas which published between March 2011 and September 2019. To do so, the PRISMA method (Preferred Reporting Items for Systematic Reviews and Meta Analyses) has introduced and applied and 39 papers have selected. These papers selected among all papers had indexed in Scientific Information Database (SID.ir) and Comprehensive Iranian Humanities Portal (ensani.ir) which include one of these keywords: housing indicator, urban housing. Complete information of these papers has cited and method, data resources and conclusion of each paper discussed briefly. Some criteria introduced and measured to evaluate different aspects of selected papers considering PRISMA suggestions. The most cited sources (papers, books, dissertations and statistic reports) have identified and applied in conclusion.
The results have shown that applying quantitative methods on urban indicators led to analogous assessments in various contexts and using novel methods and models, especially applying qualitative and mixed methods would resulted in novel and efficient perspectives to future urban housing programming and applying the PRISMA method would increase quality of survey reviews and strongly recommend to achieve comprehensive and qualified study of similar researches.

Abstract
The Great Khorasan in northeast Iran has a variety of surface structures and plains and high peaks, but due to its vicinity to the deserts of Afghanistan and Turkmenistan, it is affected by dust all the time, especially in summer. The purpose of this study was to simulate summer dust in this region by RegCM model. For this purpose, during the period 2000 to 2017, three extreme dust events were selected. The satellite image used to confirmed dust mass presence and then the synoptic structure was analyzed. Finally, the simulation results of RegCM 4.6 model were compared with the observational data including the horizontal visibility and aerosol optical depth (AOD) of Aqua satellite. The synoptic analysis showed that during the summer, low thermal pressures form in the southern Afghanistan and high pressure in the north. This structure lead to the development of north and northeast winds with speeds of 12 to 21 m / s and dust emission on the eastern border of Iran and western Afghanistan. Investigation of RegCM accuracy done by visibility, Aquas’s AOD showed that model performance in South Khorasan is better as Razavi Khorasan. The highest correlation coefficients of AOD of model and horizontal visibility were obtained at Khorasan central stations including Gonabad, Ferdows, Nahaband and Ghaen at -0.82, -0.77 and -0.44 respectively. RegCM model performed a better dust simulation in severe dust with a horizontal visibility down to less than 1000 m, high continuity and horizontal extension. Overall, the RegCM model underestimates the AOD value for the Aqua satellite algorithm.
