In the piedmont and coastal plain of NC, riparian buffers and vegetated swales are important tools for communities to manage the health of their streams. However, determining where vegetated swales and buffers would have the greatest impact in a watershed can be complex. In this study, we present a methodology for modeling the impact of riparian buffers on stormwater runoff using the SIMWE (SIMulated Water and Erosion) model, implemented with GRASS GIS in a Jupyter Notebook via the recent grass.jupyter package. We simulate a 30-minute heavy rainstorm with 3 different scenarios: no buffered (current), a 15m buffer and a 30m buffer and account for water caught by vegetation interception, slowed water velocity and increased infiltration in the buffer or swale. Our study area is a small watershed in the headwaters of the Marsh Swamp stream near Clinton, NC. The Marsh Swamp watershed is in the Atlantic coastal plain and is dominated by agricultural fields and commercial swine feeding operations, both of which contribute to low water quality in streams and increased susceptibility to flooding. This workflow lays the foundation for developing accessible open source tools for stakeholders to explore the efficacy of different buffer implementation strategies across a watershed.
