Abstract:The Sediment and Erosion Control Laboratory (SEC Lab), formerly the Hydraulics, Sedimentation, and
Erosion Control Laboratory, is operated by the Texas A&M Transportation Institute’s Environment and
Planning Program. Performance evaluation programs for sediment and erosion control products, materials,
devices and techniques are conducted at the SEC Lab to produce and maintain the Texas Department of
Transportation’s (TxDOT) Approved Products List (APL). By 2012, the existing facility was operating at
full capacity with a waiting list of over 18 months. Expansion of the facility includes an indoor rainfall
simulator that houses three 8 ft. × 40 ft. soil-fill test bed, a covered soil storage/bed preparation area, and a
covered preparation area between the existing and new buildings, and a sediment retention device flume. The
expansion of the SEC Lab provides additional performance evaluation and research capacity to better serve
TxDOT’s needs and enable a more robust and comprehensive research program.
