Interpretive Summary:

Technical Abstract: Increased environmental concern about surface water pollution has heightened the need for small, in-field runoff collectors to assess the impact of land management practices without altering the landscape. We modified a low-impact surface flow sampler designed for sheet flow by Sheridan et al. (1996). Modifications were made to accommodate steep slopes (3 to 15%), large flow rates, and channelized flow, which are common in the Southern Piedmont. The runoff collector consists of two sample splitters (10x and 100x) and two sample collectors. Five runoff collectors were placed in each of three 0.8-ha gauged watersheds to measure the quantity and quality of surface runoff. Mean volumes and concentrations measured with the runoff collectors were compared to the volumes and concentrations measured with the gauged watersheds.
