This study evaluated the relationship between stream flashiness (the day-to-day differences in streamflow) and watershed-scale estimates of the following variables: percent imperviousness, extent of urban development, and population density. The goal was to determine whether regional, publicly available datasets are reliable for use in historic landscape analyses that aim to detect hydrologic changes.
