Book excerpt: The objective of this research was to arrive at a quantitative and qualitative assessment of nonpoint sources of potential excess N under different land use/land cover (LULC) categories in the Neuse River Basin on a seasonal time scale. This assessment is being supplied to EPA's Landscape Characterization Branch, National Exposure Research Laboratory, in Research Triangle Park, NC, for inclusion in a hydrologic model to predict seasonal fluxes of N from the terrestrial landscape to surface receiving waters and groundwater in the Neuse River Basin. The analysis was performed in the following five steps: (1) development of a conceptual model to predict potential excess N on land, (2) a literature review to parameterize N fluxes under LULC categories found in the Neuse River Basin, (3) acquisition of high resolution (15-m pixel) LULC data from EPA's Landscape Characterization Branch, National Exposure Research Laboratory, in Research Triangle Park, NC, (4) acquisition of a soil N inventory map for the Neuse River Basin, (5) calculations of potential excess N on a seasonal basis for the entire Neuse River Basin.

This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonpoint sources of pollution may be responsible for as much as 50 percent of current water quality degradation in the United States, and as much as 70 percent in the Southeast. In this study, I used an ecological risk assessment methodology, at the watershed scale and riparian scales (zones 300, 100, and 50 feet on either side of streams), to analyze and quantify the impact of nonpoint pollution on the ecological integrity and water quality of North Carolina streams. Specifically, I determined how land-use patterns relate to aquatic ecological integrity, including the extent to which one of the most widely promoted best management practices (BMPs) - the preservation of riparian vegetated buffers - correlates with better ecological integrity. The central goal of this project was the creation of a set of empirical models that describe the vulnerability of North Carolina aquatic ecological integrity - as measured by benthic macroinvertebrate community structure - to changes in the landscape-scale sources of nonpoint pollution. The models, the result of multiple regression analysis of Geographic Information System (GIS)-derived data, take into account watershed eight land form characteristics, and three land cover types derived from 1992 Multi-Resolution Land Characterization (MRLC) Consortium raster data: forest, urban, and agriculture. The land form characteristics considered in this analysis are topographic complexity, mean elevation, watershed slope/relief ratio, watershed area, watershed shape, rainfall, soil clay content, and ecoregion. The regression equation models created by this process can be used by managers and policymakers to weigh the risks of management and policy decisions for a given watershed or set of watersheds, including whether vegetated riparian buffers are ecologically effective and economically efficient in achieving water quality standards. The coefficient of multiple determination (R2) for each equation indicates the p.

Available in PDF, EPUB and Kindle. Book excerpt: The potential nitrogen loadings from on-site wastewater treatment systems (septic systems) to North Carolina's river basins have long been ignored. Yet the potential for these systems to have significant impact on surface water exists. This study assessed nitrogen inputs from septic systems on macro (large watershed) and micro (small watershed) scales. Cumulative potential nitrogen loadings from on-site systems to North Carolina's 17 river basins and 134 major sub-basins were estimated using census 1990 data. The soil and water assessment tool (SWAT) model was used to predict the fate and transport nitrogen derived from on-site systems as well as nitrogen exports to surface waters in small watersheds. The sensitivity of the SWAT model output to sources and resolutions of Digital Elevation Model (DEM) inputs on a micro scale was assessed for small watersheds. A Geographic Information System (GIS) based area-driven normalization procedure was developed and implemented to estimate potential nitrogen loadings on the macro scale. Septic system density ranged from 5 to 20 systems/sq. km at a river basin level and 2 to 115 at a sub-basin level. Total potential nitrogen loading from on-site systems was approximately 14 million kg statewide. A small watershed in the lower Coastal Plain was modeled using SWAT to quantify the nitrogen export to the watershed outlet on a micro scale. Over 95% of the septic system derived nitrogen was removed prior to stream discharge. Both the source and resolution of the DEM inputs affected the size of the watershed delineated, flow volume and predicted nitrogen export to the watershed outlet.
