What are some environmental impacts of urbanization on rainwater management, stormwater runoff, and water quality in urban watersheds and coastal areas?

Urbanization can alter rainwater management, stormwater runoff, and water quality in urban watersheds and coastal areas by increasing impervious surfaces, reducing natural infiltration, and exacerbating pollution from anthropogenic sources such as industrial discharges, vehicle emissions, and stormwater runoff. These impacts can degrade water quality, impair aquatic habitats, and exacerbate flooding and erosion in urban environments, highlighting the importance of sustainable urban planning and stormwater management practices.
