Spatiotemporal Dynamics of Road Salt in a Highway Bioswale: A Comparison of Point and Continuous Monitoring Methods Open
Stormwater entering stormwater control measures (SCMs) from roadways can carry high loads of deicing salt, which can impede vegetation growth. We investigated spatial and temporal patterns of soil conductivity to compare point and continuo…

Modeling bioinfiltration surface dynamics through a hybrid geomorphic-infiltration model Open
Bioinfiltration systems are an increasingly prevalent mechanism for urban stormwater mitigation. One major challenge for the sustainability of bioinfiltration systems is erosion and channelization due to high bed shear stresses developed d…

Variability of urban drainage area delineation and runoff calculation with topographic resolution and rainfall volume Open
Designing green stormwater infrastructure (GSI) requires an accurate estimate of the contributing drainage area and a model for runoff generation. We examined some factors that add to the uncertainty associated with these two design steps …

Mineral surface area in deep weathering profiles reveals the interrelationship of iron oxidation and silicate weathering Open
Mineral specific surface area (SSA) increases as primary minerals weather and restructure into secondary phyllosilicate, oxide, and oxyhydroxide minerals. SSA is a measurable property that captures cumulative effects of many physical and c…

Testing the Fill‐and‐Spill Model of Subsurface Lateral Flow Using Ground‐Penetrating Radar and Dye Tracing Open
Core Ideas Lateral flow patterns revealed by dye tracing agreed with time‐lapse GPR data. Lateral flow downslope varied from <1 to 1 m at adjacent sites. 3D radar detected banding in the strike direction but dye fingering did not. Fracture…
