Definition
Hydrological impacts of urbanization refer to the alterations in the natural water cycle caused by urban development, which include changes in surface runoff, groundwater recharge, and water quality due to increased impervious surfaces and modifications to drainage systems. These impacts can lead to increased flooding, reduced water availability, and degraded aquatic ecosystems.
Summary
Urbanization has profound effects on hydrology, altering natural water cycles and increasing runoff. As cities grow, impervious surfaces like roads and buildings prevent water from soaking into the ground, leading to higher flood risks and degraded water quality. This change can harm local ecosystems and affect water supplies. To mitigate these impacts, urban planners and environmental scientists advocate for best management practices and green infrastructure. These strategies not only manage stormwater effectively but also enhance urban environments, making them more sustainable and resilient to climate change. Understanding these concepts is crucial for future urban development and environmental protection.
