In order to prepare a flood zoning map in the study area, seven main criteria including slope, land use, vegetation, lithology, drainage network density, topographic wetness index (TWI) and Stream power index (SPI) were selected and studied. In the next step, based on the AHP method, a matrix of pairwise comparisons of criteria and sub-criteria was prepared and their opinions were recorded in Expert Choice software by interviewing experienced experts and the weights of criteria and sub-criteria were calculated. Finally, the flood risk map in GIS environment was produced using the linear weight combination (WLC) method by converting each criterion into a raster layer based on AHP weights, which shows an area of 7.6 square meters of high and very high risk in the region. This map shows the high risk of flooding around the Pit Mine area due to the high altitude and slope in this section. Also, the risk of flooding is high at the site of the new acid plant and gas power plant within the complex. Elsewhere in the complex, flood risk is low and moderate. The results of this study can help experts and planners to determine the development process of the plant, mine and planning to reduce flood risk in the complex. Manuscript profile -

To begin, interviews were conducted with 16 university experts, managers and senior experts of railway facilities and environmental organization about blown sand mitigation in Iran. The data were coded and 77 components were identified in the form of 21 categories. Then the research model was designed and the hypotheses were identified based on the grounded theory (GT). Secondly, structural equation modeling (SEM) using Amos software was performed to fit the model. Next, interpretive structural modeling (ISM) was applied in order to prioritize, communicate and sequence between the components. The priorities of the influential components of the environmental planning model for blown sand mitigation in Sistan and Baluchestan railway tracks and stations were classified into six levels based on the expert opinions. Among them, two indicators of identification the existing conditions and the requirements for blown sand mitigation in railway tracks and stations and the goal setting for them based on their existential mission were proposed as the most effective levels. Finally, removing legal obstacles and formulating policies compatible with the environment and considering the long-term, medium-term and short-term planning of stabilization of blown sands based on executive power in order to determine applicable goals in policy priorities were proposed as solutions for controlling blown sand hazards along the Sistan and Baluchestan railway.

The main purpose of this research is to identify the influencing factors on land use changes in the villages of Astane Ashrafieh County. In the first part of the research, Landsat satellite images were used to investigate land use changes. In the second part, factors affecting land use changes were analyzed using statistical analysis. Based on this, 28 villages of the County were studied as a case study. The research method was descriptive-analytical.Questionnaire technique was used to collect data and statistical methods were used to analyze data. The results showed that among the independent economic indicators, the benefits of investing in the land and housing sector had the strongest correlation and relationship with land use changes. Among the independent social indicators, the indicators of the role of the owners of the second house in the village and the increase in the number of residential tourists and the need for land for construction had the strongest correlation and connection with land use changes. Among independent physical indicators, tourism in the study area had the highest correlation and relationship with land use changes. Correlation analysis between independent institutional-management indicators and land use changes showed that indicators of the weakness of executive bodies in informing agricultural land owners about the type of land use and the prohibition of land use changes had the highest correlation and a very strong relationship with land use changes in the village.
