Water is one of our most important natural resources.  Our faculty are playing vital roles to improve our knowledge of the interactions between the biosphere-atmosphere-lithosphere in an effort to better understand the effects of climate change and other stressors on terrestrial ecosystems.  

The faculty research focuses on forested ecosystems in both natural and urban settings. The faculty with an emphasis in ecohydrology include: Dr. Luc Claessens and Dr. Del Levia.  Their research is being conducted at a variety of scales from watershed to individual trees to individual leaves and branches using field measurements, laboratory techniques, and simulation models. 

Some specific research projects our faculty and students are involved with, include the following:

>> Effectiveness of urban stormwater retrofitting in reducing nitrogen export: A case study from the Delaware Piedmont (Dr. Luc Claessens)

>> Geospatial analysis of nitrogen removal by riparian buffers (graduate student Thomas Santangelo, Dr. Luc Claessens, Dr. Gerald Kauffman)

>> Throughfall drop size distribution in relation to leaf canopy state (graduate student Sean Hudson, Dr. Del Levia)

>> Quantifying the hydrological ecosystem services of Wilmington, Delaware’s urban forest (graduate student Asia Dowtin, Dr. Del Levia)

>> Stream network fragmentation and drought combine to drive native fish from the Great Plains (graduate student Sarmistha Chatterjee, Dr. Melinda Daniels)

The department offers educational programs for students with interests in hydrology that range from our undergraduate Environmental Science BS with water science concentration, the Geography BA, Geography MS, and a Geography PhD.    You can find additional information about each program under the “Academics” on the main menu bar or contact the Department of Geography Chair Dr. Del Levia at
