Quantifying Nutrient Pollution Reductions Achieved by Erosion Remediation Projects on Vermont's Roads

Brief Project Description: We used terrestrial lidar surveys and airborne lidar data to quantify rates of gully change at road drainage outfalls. Experimental installations of gully stabilization projects, along with retrospective assessments of erosion control projects on the state’s transportation network provide insights into the efficacy of investments in erosion remediation. This work provides Vermont-based data for estimating pollutant reductions that may be achieved by addressing erosion at road drainage outfalls in the state.
