However, tourism is a serious threat to the environment due to the continued development of urbanization and industrial transformation. Hence, the present study aims to identify the driving factors affecting the ecological security of tourism considering the capacities of the karun river. The method of this study is explanatory based on the new methods of future research. The factors were evaluated by 30 experts and specialists in urban planning using environmental scanning, and interaction/structural effects analysis. MICMAC future research specialized software was used in this regard. The results revealed that the dispersion state of the effective variables indicates the sustainability of the system. Based on 31 investigated factors, 10 primary factors were selected as key factors affecting the ecological security of tourism. All factors were repeated in both direct and indirect methods. The results indicated that the variables related to the dimensions of the scale and profit of tourism as drivers of the tourism industry have been preferred over the objectives of protecting the environment and environmental resources. Variables such as the number of employees in the tourism industry, the income from international and domestic tourists, the number of star hotels, the ratio of educational expenses to public finances, the number of international and domestic tourists, the total retail sales of hotels, catering services, and unemployment rate and urbanization are prioritized. This study revealed that the tourism capacities in the ahvaz metropolis, especially the karun river, have been abandoned due to mismanagement. Also, the results suggest that tourism planning has not been considered and the use of foresight and forecasting tools can facilitate the achievement of tourism goals. Manuscript profile -

For this purpose, using the topographic map and satellite images, the exact course of the river was determined and the initial processing was done on its information. Then flood zoning was obtained with return periods of 500 years, 200 years, 100 years, 50 years, 25 years, 10 years, 2 years.Methods: In this research, flood zoning of Karun river, which is one of the main and permanent rivers of Khuzestan province. was investigated in the area from Zaras Castle to Jafar Abad. The aim of the current research is to zonate the risk of flooding occurrence and identify the villages at risk of flooding, through the preparation of the river boundary map for the return period of 500 years, 200 years, 100 years, 50 years, 25 years, 10 years, 2 years in the Karun river using the Hec-RAS model in the ARC-GIS environment. In this research, the discharges of this river are based on the probability of its occurrence using Johnson sb statistical distribution was calculated.Findings: In this research, in addition to calculating flood depth and flow velocity parameters, factors such as shear stress and flow strength for different return periods were calculated and investigate. Shear stress and flow strength are effective parameters in the flood risk, so it is important to investigate them.Results: In this research, flood inundation risk zoning was done and the villages at risk of flooding were identified by preparing a map of the River boundary for the return period of 500 years, 200 years, 100 years, 50 years, 25 years, 10 years, 2 years, and Discharges of this river were calculated based on the probability of its occurrence using the statistical distribution of Johnson sb. Among the 10 villages located along the Karun river, Jafarabad villages, Hasht Lak Kanaar, Zaras Qala, Lali New Road bridge are the most vulnerable areas, which regardless of the rules of construction and non-observance of the river boundary are built in its main bed. Factors such as the change of land use and the transformation of floodplains into agricultural and garden lands, disregarding the river boundary and encroaching on the floodplain of the river have increased the potential of flood risk and as a result the villages are more vulnerable, especially in the flood zone with a return period of 500 years.

In this study, the Sentinel-2 satellite images were used to estimate the concentration of acidity, bicarbonate and sulfate parameters. Initially, Sentinel-2 satellite images were pre-processing and then bands and spectral indexes were determined to identify the significant relationship between the parameter values of water quality and images using the multivariate regression method. In the next stage, using Artificial neural network (ANN) and Adaptive Neuro fuzzy inference system (ANFIS) models, the relationship between Sentinel-2 satellite images and water quality parameters were modeled and then their accuracy was calculated for real values. The results showed that in the modeling of sulfate parameter using Sentinel-2 satellite, ANFIS model with relative error equal to 0.0773 and RMSe equal to 0.8014 has a higher accuracy compared to ANN models with relative error equal to 0.1581 and RMSe equal to 1.2477. While, the relative error of the results of the ANN model are obtained 0.0064 and 0.0556 for acidity and bicarbonate parameter, respectively, and RMSe is equal to 0.0702 and 0.2691, respectively. The ANFIS model has a relative error of 0.0165 and 0.0722, and RMSe is 0.1975 and 0.3037 for acidity and bicarbonate parameter, respectively. Finally, using satellite images, the mentioned models were applied to prepare a qualitative map of each parameter along the part of the Karun river. Manuscript profile -

Therefore, understanding and understanding of the water quality of rivers and their zoning based on the quantity of different elements will help us to make management decisions and reduce water pollution. The purpose of this research is qualitative zoning of Karun River in Khuzestan province in Masjed Soleiman to Ahvaz using fuzzy logic and hierarchical analysis (FAHP). For this purpose, qualitative parameters including: chloride (CL), sodium sorption ratio (SAR), electrical conductivity (EC), sodium (Na), and total dissolved solids (TDS) were used in November 1977. Qualitative parameters were first zoned using IDW interpolation method. Then, each of the obtained maps were fuzzy incremental linear membership function. Then, by preparing a questionnaire, paired comparisons between parameters based on the role of these parameters in determining water quality for agricultural consumption and based on AHP method, weight coefficients of each parameter were obtained. Came. Multiplying the weighting coefficients in the fuzzy layers and combining them, obtained a zoning map for agricultural use. The results show that the Gotvand, Arab Asad, Shahid Abbaspour and Gargar Shushtar stations are very suitable for agricultural use. Ahwaz and Malasani stations were located in a suitable area for agricultural use and Valiabad and Tang Dolab stations were located in a very unsuitable location for agricultural use.
