Background and Objectives: Due to its arid and semi-arid climate, Iran experiences high rates of evaporation from open water bodies, leading to the annual loss of substantial volumes of water. In this context, the application of novel technologies to reduce evaporation has emerged as an important strategy for sustainable water resource management. The objective of this study is to evaluate the performance of a silica-based evaporation-reducing agent at a semi-industrial scale and to investigate its quantitative and qualitative effects on surface water resources
Research Methodology: The experiments were conducted in the Shamil and Nian Dam area in Hormozgan Province using two experimental ponds, one serving as a control and the other treated with the silica-based evaporation-reducing agent. Evaporation rates were monitored over a three-month period using both manual and digital methods. To assess the impact of the agent on water quality, periodic sampling was performed and parameters were measured.
Findings: The results indicated that the silica-based evaporation-reducing agent led to an average reduction of approximately 15% in evaporation compared to the control pond. From a water quality perspective, no significant changes were observed in most physical and chemical parameters.
Conclusion: The findings demonstrate that the silica-based evaporation-reducing agent can be an effective tool for reducing evaporation from open water resources. Although no significant adverse effects on water quality were detected, the observed changes in color and algal growth suggest that environmental monitoring and optimization of the agent’s formulation are necessary for large-scale applications.
