Abstract:The TTI/TxDOT Hydraulics and Erosion Control Laboratory conducted a series of evaluation procedures to determine the field performance of flexible erosion control materials. The objectives of the study included determining the effect of flexible materials on the germination and growth of native grasses and evaluating the effectiveness of the materials for the prevention of erosion on typical steep, roadside slopes before the establishment of permanent vegetation. Researchers repeated the vegetation establishment and soil retention portions of the evaluations on two soil types with the option for two different slopes according to the manufacturer's preference. Researchers conducted the vegetation establishment evaluation by hydraulically applying the seed and fertilizer mixture on the plot, installing the erosion control product according to the manufacturer's published literature, and collecting data periodically throughout the growing season.
