The continuation of drought and the simultaneous increase in dependence on underground water sources in the past decades have expanded the range of areas subject to subsidence to many different parts of the country, which results in a lot of damage.In order to reduce the damages caused by land subsidence, it is necessary to have a complete and accurate understanding of this phenomenon. In recent decades, the virtual aperture radar (SAR) interferometric technique has become a common method for measuring subsidence. In this research, field data such as piezometric wells and groundwater drop in the minimum and maximum periods and exploitation wells were used to calculate the amount of discharge in the aquifer using IDW interpolation, aiming at analyzing the time series of the subsidence of the Esfarayen plain. besides, radar data including Sentinel 1 images were used to calculate the subsidence rate in the first 8 months of 2023. The results of the research show that the amount of subsidence in the study basin was from 1 to 12 mm in a period of 8 months and 75.2% of the area of ​​the basin was in the medium critical and very critical zone, which can be recognized based on this. He showed that the Esfrain plain is in a critical state.The most water extraction and subsidence has been related to to south of Sankhasat, south of Kharasha, south of Arg, south of Gazan, Jafarabad Kharaba and Mehdiabad of Kal Beko wells, which are located in the very critical area and require efficient management of groundwater resources in order to control land subsidence.

In public organizations such as municipalities, the design and deployment of a performance and control assessment system can lead to the proper management of urban managers on the road to achieving goals, tasks, strategies and development plans and urban development, in accordance with the quality, cost and time desired. Therefore, this article attempts to study the satisfaction of urban performance in urban services by using the views of citizens of the city of Farouj. For this assessment, using theoretical studies, 21 types of urban services were selected in three sections: Technical, Public and Cultural Services. At the next stage, the questionnaire was designed based on these services. Then, 400 questionnaires were distributed among the citizens of the case study city. In the next step, 380 questionnaires were completely and correctly collected and entered into SPSS software. Finally, the results of the study were analyzed by statistical tests. The results of the research indicate that the average satisfaction rate of public services in the city of Farouj is 3.53, which can be said that the level of citizens' compliance with this service is in the middle level. The average satisfaction rate of technical services in the city of Farouj has been calculated to be 3.31, and the average satisfaction rate of cultural services in city of Farouj has been calculated to be equal to 3.5. The results of statistical analysis indicate that the level of significance is more than 0.05 in relation to four of the urban services. This means that in terms of the services of sports spaces, the collection and disposal of surface water, the quality of leisure travelers and the respect of the clients, the level of satisfaction of citizens is equal to the average. In relation to two indicators of pedestrian quality and public participation, the mean difference with the statistical test was calculated to be 0.16 and -0.19 respectively, which indicates that the satisfaction of these services is lower than the limit on average. In other indicators, citizens' satisfaction is above average

Cities are dramatically turning into complex social, economic, and environmental systems. Each urban system is vulnerable when it can not adapt to its changing conditions and critical situations. Therefore, in recent decades, natural disaster response approaches have introduced a new concept of urban resilience to prepare for disaster as much as possible. Is. Despite the recent attention and the abundant use of the concept of resilience in different areas of theoretical and practical limitations of this concept, this study aims to explain the causal pattern of resilience of cities. The present research is based on the descriptive-causal methodology. The statistical sample of the study was compiled by 35 experts and specialists in urban planning. Fuzzy Dumbled Fan was used to achieve the research goal. The findings of this study showed that based on the values ​​of D-R, among the four metrics of urban resilience, the physical criterion with the value (0.943) was the most effective measure of resilience in the city. Also, based on the D + R values, the physical criterion with the value of (896/2) was identified as the most important resiliency criterion in the city.

One of the main tasks of urban and regional planners is the allocation of land to various urban uses, taking into account the role and function of the city, the city's economy, as well as the impact of interoperability of the users on each other. The topic of optimal location of therapeutic use is considered with consideration of effective parameters and factors in this research. According to the current situation in Shirvan, there are 3 clinics in Shirvan that their distribution and location seems to be inappropriate. Therefore, for prospective plans and according to the horizontal development of the city, assessment of these bases it is also a good idea to suggest places to establish clinics. This research is aimed at finding optimal location of clinics in Shirvan city by providing appropriate model. The research method is descriptive-analytical. In the first stage, identification and investigation of the effective factors on site selection of databases was investigated. Then using Arc GIS software, after completing the data gathering steps, preparing information layers, classifying and evaluating the layers, and weighing and overlapping the information layers were designed to prioritize the lands of the city of Shirvan for the establishment of clinics. The results showed that the clinics focus on the eastern side of the city, and central and western parts of the city are severely restricted in terms of access to clinics, and the population of 83,000 people in the city is only 28136 people in The standard radius of clinics is standard; in other words, about 75% of the population of the city is outside the standard radius of clinics and the radius of access to clinics is not suitable for citizens of the city. The city of Shirvan needs another hospital that is located in a location on the western side of the city.

Complexity of multi dimension developments and infrastructures intensifies the land related challenges to adopt legal laws, restrictions and responsibilities.  Although, multi dimension estates have been registering for many years, as the complexity of the estates are increased, disadvantages of the 2D cadaster is more appeared. Hence, the 3D cadaster has been a necessity for sustainable development. Visualizing is one of the important components of 3D cadaster. In the current research, for efficient and effective visualization of land ownerships and their related 3D information, firstly, the needed essentials of cadaster visualization systems have been classified into 3 groups including: cadaster, visualization and independent properties. Then, the trends of 3D visualization developments for older plugin and WebGL based technologies have been considered. Finally, a number of the most important systems according to the needed criteria for web-based 3D cadaster were evaluated and consequently, Cesium virtual environment has been selected as the best for the development purpose. To develop a system for 3D cadaster visualization, 2D building properties was converted to 3D using different software and then, land law properties were added and subsequently, Building Information Model (BIM) was provided. HTML5, JavaScript and CSS languages along with WebGL library and Cesium API were utilized. The implemented service is able to display WFS-based standard vector layers as well as WMS image of OGC standard. The system has the possibilities of 3D visualization like web-based 3D cadaster visualization and land law properties over the web. This enables the user to make the printed output of BIM along with descriptive information of the buildings.

Groundwater resources are important part of the sweet water available to humans. The present study studies and evaluates the quality of water resources of karstic basin of Roein Esfarayen. For this purpose, sampling of water from water sources was carried out and groundwater quality of the area was evaluated in terms of drinking, agriculture and industry using Schoeller, Wilcox and Langelier diagrams, Water Quality Index( WQI) and groundwater quality index (GQI). According to the results of the analysis of the samples taken and the relevant charter diagrams, most of the water sources in the area were in the good category for drinking. The results of the Wilcox diagram showed that only S7 (Springs of Zargara), S6 (Springs of Sarang Zwucha) and S20 samples (rivers at the basin outlet) had saline water but could be used for agriculture and the rest were suitable for agriculture. The water quality table of the region's springs in terms of industrial use also showed that all of the water samples of the region except the Springs of Sangvah, which contains sediment-bearing water, have corrosive properties. The WQI index is also indicative of the quality of all samples taken in drinking water, and only the surface water of the basin outlet whose WQI is above 50 is in good condition. Location and quality zoning of drinking water from the GQI index was also carried out. The GQI quality index in the region varied from 93.42 to 95.87 in the region. Therefore, it can be said that although the minimum quality of samples is related to surface water of the basin, but this quality value is also in the appropriate quality category. Therefore, in total, all the water resources of the study area are in the category of quality in terms of drinking water standards
