Heterogeneity in the Urban Landscape: Impacts on Hydrologic Processes and Nitrogen Pollution

Аннотация

The objective of this dissertation was to define the most critical features of the heterogeneous urban landscape that characterize nitrate source/sink dynamics and hydrology driving stream nutrient pollution. This volume of research evaluated the usefulness of the commonly used National Land Cover Database (NLCD) for deriving urban hydrologic parameters, defined metrics linking suburban landscape structure and nitrogen fluxes, and determined variance of hydrologic properties of residential lawns according to social and physical factors. Field research and remote sensing analysis took place within watersheds of the Baltimore Ecosystem Study (BES) Long-Term Ecological Research (LTER) site.
