Abstract: Urbanization decreases watershed infiltration by sealing soils with impervious cover. Increased runoff from impervious surfaces is conveyed directly into urban headwater streams through storm sewer systems, thereby altering streamflow regimes, transporting thermal and chemical pollution, and subsequently reducing aquatic biodiversity in downstream ecosystems. Urban watershed restoration activities that enhance watershed infiltration might improve downstream hydro-ecological function, including flow regimes, water quality, and eventually aquatic invertebrate diversity. To test this hypothesis, I will conduct high-frequency hydrometric monitoring and characterize the biophysical conditions in urban streams whose watersheds have been restored with infiltration-based restoration, as well as urban degraded and forested streams.
