RES2020-24: Quantifying Support Practice Sub-factor Values for Erosion-control and Sediment Retention Devices- Phase II

The scope of the research project includes using an in-house, physically based, runoff-erosion model to quantify sediment fluxes for scenarios both with and without different EPSC practices in each of the TDOT regions across the state. The model will be calibrated with data from physical experiments performed as part of RES: #2016-20 and validated with new field and/or laboratory experiments. From each set of simulations, C or P factors will be determined as the ratio of sediment fluxes with the EPSC practice to sediment fluxes without the practice. The project team will provide a statistical distribution of the C and P factors for each EPSC practice that are reflective of the heterogeneity in characteristics within a region and will capture variances arising from the different rainfall-runoff, erodibility, and slope-length characteristics across the region.
