Evaluation of Soil Class Proxies for Hydrologic Performance of In Situ Bioinfiltration Systems

Lee, Ryan S. / Traver, Robert G. / Welker, Andrea L.

The hydrologic performance of in situ bioinfiltration systems (bioretention systems with no fill media or underdrain) is quantified and soil classes are evaluated as proxies for design requirements. A one-dimensional (1D) Richard’s equation model of a bioinfiltration system is used in combination with a dataset of soil hydraulic properties to conduct a Monte Carlo analysis of the effect of soil hydraulic properties; the results are summarized both by soil textural class and by hydrologic soil group (HSG), showing that textural class is generally a poor proxy for estimating the infiltration performance of in situ bioinfiltration cells ( $R^{2} = 0.40$ ). Because infiltration measurements are required to estimate the HSG, they are a better proxy for bioinfiltration performance ( $R^{2} = 0.89$ ). It is found that soil proxies do provide certain reliable guidelines: HSG-D soils always require engineered fill media with an underdrain; whereas underdrains are not necessary for sand, loamy sand, HSG-A, and HSG-B native soils. Minimum bounds on the design capture volume are generated for these soils which may be substantially larger than the surface storage volume.
