Urban hydrology is the study of how water moves through urban areas, focusing on the impact of human activities on the water cycle. It examines how rainfall, runoff, and drainage systems interact in cities, where natural landscapes have been altered by buildings and roads. This field helps in understanding issues like flooding, water quality, and the availability of freshwater resources. Effective urban hydrology management involves designing infrastructure such as stormwater management systems and green roofs to control water flow and reduce pollution. By implementing sustainable practices, cities can improve their resilience to extreme weather events and enhance the overall health of urban ecosystems.
