Research Our research group is primarily interested in the structure, function and dynamics of watershed systems. In this work we combine field measurement and observation of hydrological and ecological variables with the development and application of distributed simulation models, GIS and remote sensing techniques. Our projects are particularly concerned with the integration and coupling between water, carbon and nutrient cycling and transport with watersheds, and the interactions of human individual and institutional behavior as part of watershed ecosystems. Currently we are working in a range of watersheds within forested, agricultural and urban environments. This encompasses a set of LTER sites, as well as sites within and near Chapel Hill, NC. Our major research site is in the Baltimore Ecosystem Study (www.beslter.org).  Previous work has included work in northern Manitoba, central Saskatchewan, central Ontario, the Loess Plateau of northern China and the Pacific Northwest. An emphasis in our work in GISci is the representation of watersheds as hierarchical systems based on a geomorphic framework of the landscape, and including the integrated patterns of topography, soils and surface materials, arranged within a progressively nested subcatchments, hillslopes, bottomlands and channels. Remote sensing techniques are used and developed to extract key attributes of vegetation canopies, along with anthropogenic features. Digital terrain analysis is keyed towards the extraction of the full flowpath network, and the partition of the catchment into the component geomorphic hierarchy features. Recent Publications D.L.
