Stream and Watershed Research Projects
|Urban Watershed Continuum Concept|
Current work is also focusing on the impacts of organic carbon quantity and quality on influencing biogeochemical processes along the urban watershed continuum (Newcomer et al. 2012). Results from streamwater chemistry at two forested, two restored, and two unrestored urban streams at the BES LTER site show that there was significant relationship between daily DOC load and daily runoff in log-log scale for all types of land-use (Fig. 1). The slope and intercept of these regressions, however, differed from site to site. These changes in DOC dynamics can influence denitrification rates in streams (Newcomer et al. 2012).
Urban Watershed Continuum: The Movie The Urban Watershed Continuum is a conceptual framework for studying urban waters. This short film explains the concept to students and educators. While exploring urban waters at the Baltimore Long-Term Ecological Research site and other locations, the film explores the question: what is an urban watershed? The urban watershed continuum concept explores infrastructure as a new part of the urban stream network and examines the transport and transformation of water across four dimensions including space and time in cities.
