Read More All-inclusive growth in all sectors along with structural reforms in institutions can lead to development. In this regard, the agricultural sector plays a key role in the development of Iran owing to its specific status. The development of the agricultural sector with a sustainability approach can greatly contribute to the development of other sectors, too. In this respect, Sistan and Baluchestan province has a special role to play in the regional economy due to its specific climatic and geographical conditions for agriculture. Therefore, this research aimed to formulate mechanisms and strategies for the development of sustainable agriculture in this province. The research adopted the gray multi-attribute decision-making technique (GRA) for modeling. Data were collected with a questionnaire filled out by experts and farmers in 2020. Based on this, 5 options and 28 indicators were finalized based on the opinions of expert experts. The software package of MCDMSOLVER.2018 was used for modeling. The results derived from the experts showed that choice taxing resource-intensive and polluting agricultural activities was ranked the top with a final score of 0.8134. Also, the use of cooperative methods and processes in the development and extension of sustainable agricultural activities was ranked second with a score of 0.71. The next ranks were for educating farmers and supporting their membership in sustainable agriculture groups and providing specific research and support services in the field of sustainable agriculture with scores of 0.571 and 0.519, respectively. The lowest ranks were assigned to Adjusting the price of products in the market in favor of healthy and ecological products, encouraging and attracting the cooperation of private and non-governmental national and international institutions in the field of sustainable agriculture, such as FAO or the Global Environment Facility and social security and retirement insurance for farmers with scores of 0.334, 0.333, and 0.298, respectively. The farmers ranked taxing on resource-intensive and polluting agricultural activities and using participatory methods and processes in the development and promotion of sustainable agricultural activities at the top with scores of 0.722 and 0.576, respectively.

Read More Increased demand for freshwater and climate change effects have shifted focus to water resource management, highlighting the crucial role of dams in addressing supply and demand challenges. One of the primary challenges associated with newly constructed dams is effectively monitoring them during the initial phase of impounding. This study investigates the combined performance of the first impoundment period of the Balaroud earth-fill dam concurrently with the final embankment levels of the dam structure. It also explores the simultaneous effects of these factors on the monitoring and stability of the Balaroud dam, providing hydrometric data measurements throughout the process. Analysis of data from the instrumentation located at the critical section of the dam revealed minor variations in the majority of standpipe piezometers and rock piezometers during the initial months of impounding. These variations were exclusively influenced by the embankment of the dam structure. Following the completion of the embankment and the subsequent rise in the reservoir level, the trend of pore water pressure changes has become aligned with fluctuations in the reservoir level. The analysis of data from the embankment piezometer and total pressure cells shows a downward trend in the pore water pressure ratio at the beginning of the impounding phase, which subsequently increased following the completion of the embankment activities and the rise in the reservoir level. During the impounding period, both the maximum pore water pressure ratio and the reliability ratio against liquefaction and internal erosion have remained within permissible and acceptable limits. Additionally, a decreasing trend in the arching ratio was observed in relation to the rising embankment level until its completion. However, as the reservoir level increased and the saturation zone expanded, the arching ratio began to rise again, indicating effective stress transfer within the dam structure despite localized arcing at specific instrumentation points.

Read More This paper presents the results of a study that simulates the sediment routing of the Ahar Chai river using the hydrologic model which calculates the accuracy of using the soil and water assessment tool (SWAT) to simulate the runoff and sediment in watershed areas that could help to predict the amount of sediment in the future. Therefore, in this paper, sediment production in the upper Ahar Chai watershed, located in East Azarbaijan province - Ahar city, was simulated by using the hydrological model of SWAT, which is an addition to the Arc-GIS environment. The model's effectiveness in this area's hydrological simulation was assessed. sequential uncertainty fitting-2 (sufi-2), a SWAT-CUP sub-module computer program was applied to optimize the parameters of SWAT using monthly observed runoff and sediment data at the Ahar Chai watershed for calibration, validation, and uncertainty analysis. In the climatological studies, data from the Ahar synoptic station were used from 1994 to 2015. The Ahar Chai basin model was used from 1994 to 2015 for precipitation data. The monthly average discharge and sediment data were also used from the Orang hydrometric and sedimentation station in the period 2000-2015. The observed statistical data of flow and sediment measured for 22 years were selected for model simulation. The determination coefficient (R2) and the Nash-Sutcliffe coefficient (NS) in the calibration stage for sedimentation were 0.81 and 0.66 respectively, and also in the validation stage, were 0.74 and 0.71. The results highlight the model’s potential for simulating sediment yield and streamflow under varying climatic and land use conditions, with performance metrics comparable to those found in similar global studies. However, this study also provides unique insights into the regional-specific challenges of applying SWAT in regions with high variability in precipitation, land use, and topography. Notably, the influence of vegetation covers on sediment yield, as well as the importance of high-quality, region-specific data for model calibration, are key findings. This research contributes to the broader body of knowledge by offering an in-depth analysis of SWAT’s performance in the Ahar Chai basin, while also addressing the gaps in current modeling efforts related to sediment transport in mountainous, semi-arid environments. The findings pave the way for future advancements in hydrological modeling and watershed management in similar regions, particularly through the integration of more detailed data and enhanced uncertainty analysis methods.
