To Restore or Not to Restore? Assessing Pre-project Conditions of a Habitat Restoration Project on the New River, North Carolina 2014 2315 The number of river restoration projects aimed at enhancing water quality, improving in-stream habitat, and stabilizing eroding banks have exploded in the past decade. Case studies and synthesized reports have found varying results, with accounts of ...
The Finer Things in Life: Comparing High Resolution Fossil Fuel Carbon Dioxide Emissions Inventories 2014 2193 The quantification of fossil fuel contributions to carbon dioxide concentrations is necessary for monitoring, reporting, and verifying carbon dioxide emissions, which is necessary for the success of international agreements to reduce emissions. Howev...
The Effects of Impervious Surfaces and Forests on Water Quality in a Southern Appalachian Headwater Catchment: A Geospatial Modeling Approach 2011 3702 The water quality of streams is impacted by the land cover types that occur within their watersheds and stream corridors. Research has indicated that impervious surfaces (roads, roofs, and parking lots) exert significant stress on stream system heal...
Structure-from-Motion based vegetation modeling and shade estimation 2015 4436 Although three-dimensional (3-D) light dimension and range (LiDAR) point cloud datasets describing the structure of vegetation have proven to be highly useful for ecological modeling, the collection of such data is expensive. However, a new technolog...
Human Systems In Watershed Modeling: A Literature Review Of Integrated Watershed Modeling In The United States 2015 1285 Water is both a natural resource and public good. It plays a critical role in a host of environmental processes and economic, social and political activities. Recent technological advancements, emerging research methods and more comprehensive dataset...
Flood Modeling and the Influence of Digital Terrain Models: A Case Study of the Swannanoa River in North Carolina 2015 3549 An increase in flood disasters nationally and internationally has highlighted the need for accurate flood modeling regarding flood insurance and emergency response. Topographic data is the most important variable in determining flood modeling accurac...
The Influence of Impervious Surface Location on Water Quality in the Headwaters of the Southern Appalachian Mountains 2013 2031 Determining where critical areas in watersheds exist, and how land cover in these critical areas influence water quality is vital. Impervious land cover has been shown to have a negative influence on water quality; however, the influence of imperviou...
