Abstract:
The goal of this project was to determine the effectiveness of the hydroseeding practice in reducing Land-Based Sources of Pollution (LBSP), with special emphasis on erosion and sediment control, at the hydroseeding sites and downstream of the hydroseeding sites. This goal was achieved using the Open-Source version of the Nonpoint Source Pollution and Erosion Comparison Tool (OpenNSPECT), a tool developed by the National Oceanic and Atmospheric Administration Coastal Services Center (NOAA-CSC) that examines the relationship between land cover, nonpoint sources of pollution, and erosion. This tool was used to compare the difference in surface water runoff, sediment, nitrogen and phosphorus loadings between a baseline landscape (i.e. pre-hydroseeding) and a managed landscape (i.e. post-hydroseeding) and subsequently to determine the reduction of sediment, surface water runoff, nitrogen and phosphorus loadings due to the hydroseeding practice. Methods included geo-referencing the hydroseeding sites in the field and digitizing their boundaries using a combination of Geographic Information Systems (GIS) and Google Earth. Geospatial data were acquired from NOAA's Office of Coastal Management, and clipped to the extent of the GB/RL watershed. Finally, using OpenNSPECT an analysis comparing pre and post- hydroseeding sites was performed. This analysis was done for six hydroseeding sites, from which five are within the RL/GB watershed. Results presenting the reduction of sediment, runoff, nitrogen, and phosphorus loadings both at the practice and downstream of the practice were produced and are presented in this report. According to OpenNSPECT changing an area from bare land to grassland reduces sediment loadings and runoff at the practice by approximately 83% and 73% respectively"--Abstract.
