الملخص	Air dispersion modeling is a quantitative method to predict the concentration and deposition of air pollutants (dust, gases, particulates) released from industrial sources, traffic, or combustion. Developed empirically by Pasquill and Gifford in the 1960s and formalized into the Gaussian plume model, these methods predict ground-level concentration downwind of a source using wind speed, stability class, source height, and meteorological data. Air dispersion models are essential tools for regulatory compliance, emission permitting, and exposure assessment.	Green infrastructure (GI) design is the planning and implementation of natural or nature-based systems (vegetation, soils, water bodies) integrated into urban environments to provide multiple ecosystem services: stormwater management, air quality improvement, heat island mitigation, biodiversity habitat, recreation, and social well-being. Emerged in the 2000s as a sustainability paradigm, green infrastructure combines landscape design, hydrology, ecology, and urban planning to create multifunctional spaces that serve practical and aesthetic goals.
