文摘

The normalized average annual runoff depth from urban land of U.S. was assessed. Urban expansion and intensification serve as drivers altering surface runoff. National annual runoff volume increased 10% from 2001 to 2011 due to urbanization. Population change alone is inadequate to analyze the increase in urban development. The L-THIA Tabular Tool is capable of assessing urbanization impacts on runoff.
