The drought occurs in a large number of livelihoods of rural households, especially in villages of border areas facing livelihoods. To deal with these effects, the use of coping strategies in rural areas is essential. Therefore, considering the importance of this issue, the purpose of this study was to investigate the effects of drought on rural communities and identify strategies for coping with its implications in border villages in Zahedan. The present research is in terms of purpose, applied and method of combined (quantitative and qualitative). The data collection tool and questionnaire were observed and interviewed with farmers and villagers. The statistical society is related to rural households in Zahedan (10278 households), which uses a simple quota and random quota sampling 380 Household was selected as the first instance. In order to analyze quantitative data, Johansson's exploratory test was used. Exploratory interviews were used to investigate and analyze qualitative analyzes. The results showed that drought in Zahedan city villages had the greatest effect on reducing water resources, cultivation, employment, income, rural poverty, number of livestock or animal products, rural migration, vegetation loss, erosion and soil salinity and reduced price Had land and land. The results of the use of coping practices among farmers in the region showed that the status of using these actions is not suitable, and more than half of the farmers do not use these methods. However, some farmers have used more relatively simple and low cost methods that do not need to specialize and with the characteristics of border villages. In terms of farmers, such as smuggling fuel and goods, leaving the village and migrate to the city, addressing non-agricultural jobs, flooring or lyrics of Qanat and manual nutrition of livestock as the most important methods for compatibility with drought and decrease The effects are it.

Water Resource plays a pivotal role in sustainable development of every area, especially in rural areas. The challenge of dehydration is one of the greatest challenges in 21st century because it can be the source of many of the world's social and ecological changes. The agricultural sector as the most important economic sector in the rural areas is directly affected by the shortage of water resources. Identifying the attitudes and solutions of indigenous farmers in facing to water deficiency plays a key role in appropriate strategies and improving the capacity of local communities to adapt to it. The purpose of this study was to investigate the attitude of farmers in the villages of Bahar County in Hamadan province toward the challenge of dehydration and identify appropriate strategies and strategies for mitigation and adaptation in the region. This research is a descriptive-analytical study. The statistical population of the study is 68 villages in Bahar County with 18376 households. According to Cochran formula, there was needed to complete the questionnaire by 375 farmers as the number of the samples. The main data were collected through a field survey using a questionnaire. The sampling method was random and the number of samples in each village was determined by proportionate stratified sampling based on the number of farmers and the questionnaires were completed randomly. Data analysis was performed using confirmatory factor analysis in Lizrel software. The attitude of the villagers towards the aridity challenge was respectively cognitive attitude with (0.883), behavioral attitude with (0.867) and emotional attitude with (0.517) of factor analysis. Therefore, it can be concluded that the villagers' attitude to the challenge of dehydration is a cognitive-behavioral. Based on this, 12 strategies consistent with the status of the region have been proposed for optimal resource management and crop water productivity.

In this article, the aim is to Recognition the features of the entrances of Pahlavi period buildings in Zahedan and then prioritize these features. The research method is descriptive-analytical and quantitative-qualitative. Data collection in the first stage is through content analysis method based on images and researcher observations of 8 buildings in the city. In the second stage, building features were prioritized through a questionnaire tool and using AHP method. The number of experts to weigh the criteria was 10 people. The result of the research shows that the architectural style of the 8 buildings studied is the traditional architectural style; A study of the typology of the entrance of the building based on the facade decorations shows that the decorations are based on the traditional architectural style and most of the designs, shapes and inscriptions on the entrance of the building include brickwork, use of simple designs and shapes. In fact, the use of bricks and materials compatible with the climate of the region with simple designs and in many cases without designs on the entrances, is the dominant species. Therefore, the predominant type of buildings at the entrance of Zahedan city is of traditional architecture and in a simple way and decorations are also based on bricks. The result of AHP method showed that simple, truncated, snake and vein decorations weighing 0.282 are known as the most important decorative features of the entrance of the building in Zahedan. The use of simple brick inscriptions weighing 0.181 is also in the second place in terms of importance in terms of decorations on the entrance of the building.

Different methods are used for baseflow separation, filtering method one of these methods.

In the past, architects in many parts of Iran had built traditional public buildings to create a community convenience and comfort. Ab Anbars are good example of this facility structures which they were suppose to collect water in rainy condition and keep it cool for use in dry condition of year espacialy in hot and arid climate. To study amount of radiation and heat absorption 2 Domes of Ab Anbar in Yazd (hot and arid climate) and 2 Domes of Ab Anbar in Qazvin (cold climate) were selected. In order to simulate the domes, they were first modeled in Revit software 2017, and then models were transferred to Rhino 5 software, using the honeybee & lady bug, and with the Energy plus Engine analysis of the received solar radiation and shading were done. In the analyzes, uniformity of the dimensions of the Ab Anbars domes were used, so that the optimum dome can be obtained in terms of receiving solar radiation and absorbing heat in the shadowed area. To equalize the domes, the absorption of the sun's radiation of each dome is divided by the amount of shadowing of the same dome.Radiation absorption in hottest day of the year in hat and arid climate and coldest day of year in cold climate were calculated using Energy Plus software Honeybee & ladybug Plugins. Result shows that amount of radiation is dependent to form of domes. During study day (14,16 and 18 o’clock ) 78, 71 and 64 percent of high rise Domes  is facing radiation while 93,81 and 64 percent of  low rise domes is facing radiation. From this results it can be concluded that high rise domes have better function in hot and arid climate and low rise domes have better function in cold climate in relation to radiation absorption.

Corona and Hexagon satellite photographs with a spatial resolution of 1.8 to 9 meters are a good source for monitoring and evaluating changes in surface phenomena. The purpose of this study is to monitor the changes in Zaribar Lake in the period 1969-2019 using the data of Corona, Hexagon and Aster satellites and their ability to monitor and extract the coastline, lake boundary and water surface. In this study, to geometric correction the corona and hexagon data from Google Earth images, linear extraction algorithms, binary mask and mean shift segmentation were used to extract the coastline and lake boundary, detect lake changes and extract and monitor the water area of ​​Zaribar Lake. The results showed that in the first step: geometric correction of corona and hexagon images was obtained using Google Earth images with RMSE of 0.3 and 0.4 pixels. In the second stage, the linear extraction algorithm for extracting the lake boundary and coastline using corona and hexagon photographs has high accuracy and has a high correlation with the topographic map of 1.50000. In the third step, the unsupervised classification of binary mask method, in order to detect lake changes using corona and hexagon photographs, acceptablely identified the altered and unchanged pixels, so that 11 hectares of lake surface had the most changes. Finally, in the fourth step, it was found that the mean shift segmentation algorithm and threshold worked better by applying the corona, hexagon, and Aster events to extract the water surface, and in the meantime, the corona image performed better due to its higher resolution. The above results showed that Zaribar Lake decreased by 6.5% from 1969 to 2019 and the findings have a high correlation with the product of the ester aquifer. In general, the findings of this study show the potential of using digital image processing methods for corona and hexagon data to monitor and detect changes in lakes.
