Q : $12345!!$##the socio$-$economic theory of urban development influence civil engineering practices in urban planning? Consider factors like infrastructure design, transportation networks, and housing solutions. Discuss how theories such as urban agglomeration, central place theory, and the multiple nuclei model shape civil engineering decisions in creating sustainable and efficient urban environments. Explore case studies or examples where these theories have been applied in real$-$world civil engineering projects, illustrating their impact on the built environment and the quality of life for urban residents. Additionally, analyze the challenges and opportunities presented by applying theoretical frameworks in civil engineering practice, particularly in the context of rapid urbanization and evolving societal need
