This research explores the use of iterative methods in conjunction with the Finite Difference Method (FDM) for solving partial differential equations (PDE). The central challenge addressed is the computational inefficiency and slow convergence that often arise when utilizing traditional numerical methods, particularly in large-scale systems. The study aims to develop a more efficient iterative approach to solve PDEs by minimizing computational time while ensuring the stability of the obtained solutions. The primary methods proposed include iterative solvers such as Gauss-Seidel and Successive Over-Relaxation (SOR), which are applied to numerical solutions derived from FDM. The research demonstrates that iterative methods, especially SOR, achieve faster convergence with fewer iterations compared to conventional methods like the Finite Element Method (FEM), which tends to be slower and more resource-intensive for large-scale problems. The study highlights the advantages of iterative solvers in efficiently handling large, sparse linear systems and reducing computational costs. In addition, it shows that these methods are capable of providing stable solutions, thereby maintaining accuracy with significantly lower computational effort. The results suggest that iterative methods, when applied in combination with FDM, offer a practical and scalable solution for solving complex PDEs. These methods are especially beneficial in engineering and theoretical physics applications where large-scale simulations are prevalent. The study concludes with recommendations for future research, which should focus on further optimizing solver parameters, exploring hybrid approaches, and extending the methods to more complex PDEs with non-linearities or irregular geometries. By doing so, these techniques could contribute to even more efficient and practical solutions for real-world applications.

Urban drainage systems face mounting pressure due to the combined impacts of rapid urbanization and climate change. The expansion of impervious surfaces and altered precipitation patterns contribute to increased stormwater runoff, exacerbating flood risks and water quality issues in cities. Traditional drainage systems, focused primarily on controlling water volume, are insufficient to address the growing complexity of urban drainage challenges. This study proposes Sustainable Urban Drainage Systems (SUDS) that integrate flood management, water quality improvement, and climate resilience. By incorporating nature-based solutions such as permeable pavements, green roofs, and rain gardens, these systems aim to reduce runoff, enhance groundwater recharge, and mitigate the negative effects of urbanization. Through a Multi-Criteria Decision Making (MCDM) framework, this research evaluates various drainage solutions based on technical, socio-economic, and environmental criteria. The findings indicate that SUDS outperforms traditional systems in flood mitigation, water quality control, and climate resilience, highlighting their importance in adapting to changing climatic conditions. This paper emphasizes the need for sustainable drainage solutions to ensure long-term urban resilience and improve the overall quality of urban environments.
