Evaluating Channelized Flow Sediment Control Practices Using Large-Scale Testing Techniques
Publication: World Environmental and Water Resources Congress 2012: Crossing Boundaries
Abstract
Ditch checks are used throughout highway construction and are a critical element in the erosion and sediment control plan. The purpose of a ditch check is to reduce flow rates, thereby minimizing channel erosion. Proper installation is required for these devices to perform as intended. Auburn University's Erosion and Sediment Control Testing Facility (AU-ESCTF) was developed to evaluate ditch check devices used in the Alabama Department of Transportation's (ALDOT) erosion and sediment control design practices. A channelized flow testing facility was developed with the ASTM D7208-06 standard in mind, along with ALDOT's design practices and needs taking precedence. Testing procedures have been developed based on ASTM D7208-06 as well as ALDOT's needs regarding ditch check performance testing. This paper presents the ditch check testing setup and results of testing runs using 20" wattles. Water depths and flow velocities at eight cross sections were measured and agree well with predicted results from standard hydraulics equations. Changes in flow velocities and energy gradient lines were used to evaluate and assess channel erosion within the ponding and discharge zones of the ditch check. Various installation practices of ditch checks and their performances (e.g., local erosions in the channel and after ditch check) are discussed.
