Short summary

We applied a hydrological model on 43 urban catchments in the United States to quantify the flow changes attributable to urbanization. Then, we tried to relate these flow changes to the changes of urban/impervious areas of the catchments. We argue that these spatial changes of urban areas can be more precisely characterized by landscape metrics. Our results showed that the catchments with larger impervious areas and larger mean patch areas are likely to have larger increase of runoff yield.
