الملخص	The Activated Sludge Model (ASM) is a standardized mathematical framework for simulating biological wastewater treatment processes, developed by the International Association on Water Quality (IAWQ) beginning in 1987. It represents the transport, transformation, and fate of organic matter and nutrients in suspended-growth treatment systems. ASM is widely used to design, optimize, and predict the performance of wastewater treatment plants under varying influent and operational conditions.	Stormwater management is the planning and engineering of urban water systems to control, treat, and utilize rainwater runoff from developed areas. Traditional approaches (pipes, detention basins) conveyed runoff rapidly to streams or treatment plants; modern green infrastructure approaches (permeable pavements, bioswales, retention ponds) reduce runoff volume through infiltration and reuse while improving water quality. Stormwater management integrates hydrologic modeling, water quality assessment, and infrastructure design to meet regulatory requirements and climate resilience goals.
