A city requires city brand and appropriate strategies for beneficiaries, especially tourists; hence, city development plans can affect the type of city brand orientations. Accordingly, this study was conducted to identify the effective factors to design structural equation modeling (SEM). SEM was employed to rank the factors and find the correlation between them using Forner-Larcker Matrix. This was an applied-correlational study in which, data were collected through convergent mixed methodology, library study, questionnaire, and Semi-structured interviews. Birjand was chosen as the research field and a statistical sample was chosen at descriptive statistics using purposive and snowball sampling methods. Accordingly, 19 subjects were selected from urban experts, and 381 tourists were chosen at the quantitative step using simple random sampling. findings obtained from interviews implied that some points should be considered for the city branding of Birjand. The factors include the significant militarily and academic impact of Birjand on historical aspect and service-based economy of the city, cultural capitals, and the arts that are forgetting, immigration, and implementing the development-driving plans. The research model indicated that city development plans had the highest positive effects on the landscape and mental image regarding city branding plans. Moreover, According to the correlation between components, the highest relationship was between mental image and landscape (0.66).

Population growth and the need for economic and social services have accelerated the demands for land and its manipulations over the recent decades. The contribution of policies and interventions of different stakeholders in land change is not adequately addressed in previous studies. This research, therefore, aims to examine the role of key stakeholders, and their policies in land-use change in the study area. In doing so a total number of 20 interviews with senior experts and informants from 13 local organizations were conducted to collect qualitative data on the form, process and cause of land-use change in the area. Atlasti software was used to analysis the interviews' data. Furthermore, Social Networks Analysis (SNA) and questionnaires were used to map the trust among the stakeholders and also the role of their policies and program on land-use changes from the perspective of other stakeholders. The results show that the policies and interventions of the municipality are playing the most significant role in land-use change via disregarding and violations of roles and related for individual illegal benefits. Additionally, departments of agriculture, rural councils are among the most trusted agents in land use governance and management. Furthermore, water shortage was the most important reason pointed out by the many interviewees for conversion of farmlands to other uses. A part from water shortage, some other reasons such as: lack of governmental support for farming, strict official constraints and difficulties in providing amenities for gardens, expensive agricultural inputs, land price increase, immigration, corruptions in local organization are identified as drivers of rural land-use change.

Natural disasters cause severe financial and human damage. Crisis management means purposefully shifting the flow of affairs in a controllable manner with the intention of returning things to pre-crisis conditions as soon as possible. Therefore, the main purpose of this article is to present a model of social capital development in urban water crisis management.The study method is descriptive-survey. In order to collect information, interviews and questionnaires were used and for data analysis, SPSS software, AHP analysis method, regression and T were used. Statistical community including crisis and water crisis managers; Also, all residents of Karaj were in the period between 1396 and 1395, which was estimated as a statistical sample of 350 people using Cochran's table.The results of statistical analysis showed that from the perspective of statistical sample individuals, the amount of social capital was lower than the desired level. Also, the relationship between social capital indicators was significant. Also, the results of couple comparison of main criteria using AHP analysis prioritized the indicators of social trust with 0.433 coefficient, incentive policy criterion and change in attitude space with 0.355 coefficient, criterion The interactive and value infrastructure of the society with a coefficient of 0.277, the interaction with a coefficient of 0.203, and finally the criterion of non-alienation with the government with a coefficient of 0.199 showed the fifth priority.The study shows that countries' ability to deal with crises has a lot to do with crisis management policy, promoting social capital in society and developing a spirit of cooperation and motivating participation among the people is one of the important solutions.

The development of sustainable entrepreneurship plays a critical role in promoting human well-being and environmental preservation. To achieve this objective, it is essential to understand the factors affecting the emergence of entrepreneurial opportunities in different regions. Therefore, this study aims to explore these factors through a descriptive-analytical survey, with data collected from documentary research and field surveys. The number of experts was 52 who were purposefully sampled using the snowball method. The study employed four indicators and 28 items, which were measured using the Likert scale. A sample of 439 individuals, consisting of 387 villagers and 52 experts, participated in the study. The selection of the 387 villagers was determined using Cochran's formula from a statistical population of 215,104 people. Descriptive statistics, such as mean and standard deviation, as well as inferential statistics, including one-sample t-test and one-way analysis of variance, were used to analyze the data. The results of the one-sample t-test revealed that all indicators examined in the study were statistically significant at a confidence level above 95%. These findings suggest that the villagers' perception of these indicators is positive, given that the observed mean value (3.1) is assumed to be positive. Furthermore, the evaluation statistics, such as the multiple determination coefficient and adjusted coefficient of determination, indicated that the transcendental model provides a better understanding of the factors influencing entrepreneurial opportunities and the key areas of entrepreneurship. The analysis of the transcendental model demonstrated that government subsidies, investment and facilities, product insurance, and education are the most influential factors in the formation of entrepreneurial opportunities. Additionally, the most important sectors for creating and developing entrepreneurship were found to be handicrafts, home-based jobs, oil and gas, medicinal plants, and date production. Overall, the results highlight the region's significant potential for natural, economic, and industrial entrepreneurship, emphasizing the necessity for the government to prioritize investment in entrepreneurship.

Relative humidity is considered to be one of the most important climatic parameters and atmospheric phenomena. The purpose of the present study is to evaluate the regional algorithms for estimating relative humidity using remote sensing data in Hormozgan province. To this end, MOD05 and MOD07 products were employed to estimate total perceptible water, air temperature, and sea-level pressure Additionally, MOD35 was used for cloud verification, , resulting in the identification of 2190 cloudless images with 95% confidence level for analysis. radiosound data of Bandar Abbas ststion and synoptic stations Covering entire Hormozgan Province. were used to evaluate the results. The findings demonstrated high accuracy of the algorithms and experimental model, with acceptable R² and RMSE values between Modis product and ground data. These results align well with ground station measurements. The province's climate was determined to be semi-desert with a long warm season and a short cool period. Further analysis revealed a strong correlation between sea-level pressure and total perceptible water (TPW) with the region's topography. Maximum TPW and sea-level pressure values were recorded in coastal lowlands, while minimum values occurred in the highlands. Based on zoning maps, Hormozgan province can be divided into four regions based on relative humidity: from very dry conditions with less than 20% relative humidity in the highlands to humid areas with over 65% relative humidity along the coast.

River morphology holds significant importance in the fields of geomorphology and river management and engineering. The marginal sections of rivers have consistently undergone changes in their riverbeds due to various social and economic factors. The Dare Ourt River, located in the Ardabil province, represents a permanent river that has experienced frequent floods and alterations in its channel morphology in recent periods. In this study, the Dare Ourt river was thoroughly analyzed using the Rosegen model at levels one and two. To conduct this study effectively, detaied data such as 1:2000 river topographic maps, hydrometric data, and boundary conditions from the Ardabil Regional Water Authority were collected and utilized. Furthermore, the HEC-RAS hydrodynamic model was employed to extract the primary indices of the Rosegen model with greater accuracy. The outcomes revealed that the majority of the river sections exhibit a C6c type, characterized by an alluvial substrate. Additionally, other dominant types observed within the four examined ranges include B6c, E6b, F6, and D. Field visits also confirmed a transition in the river type from C to F within range 4, which presents challenges for the reconstruction and restoration of the river in type F. As a recommendation, it is advised to implement restrictions to prevent the river from transitioning into type F.
