Riparian buffers are undeveloped, vegetated areas along the banks of water bodies that separate the waterbody from other land uses such as developments or agricultural fields. Buffers are well known for improving stream health since they capture nutrient and sediment runoff, increase infiltration and reduce overland water flow velocity.
In the piedmont and coastal plain of NC, riparian buffers are an important tool for communities to manage the health of their streams since a majority of the land is developed or used for agriculture. However, deciding where instituting buffers would (1) have the greatest impact on flooding and (2) are most desirable for community stakeholders can make these changes difficult to implement.
In this study, we present a methodology for modeling the impact of riparian buffers on runoff during a flood event with GRASS GIS. Our study area will be a small section of stream 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. We will simulate a 30-minute heavy rainstorm with 3 different scenarios: no buffered (current), a 15m buffer and a 30m buffer. We will account for how riparian buffers remove water caught by vegetation interception, slow water velocity and increase infiltration. 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.
