in an Urban World: New Contexts for Hydraulic Conductivity.

Hydraulic conductivity () is a key hydrologic parameter widely recognized to be difficult to estimate and constrain, with little consistent assessment in disturbed, urbanized soils. To estimate , it is either measured, or simulated by pedotransfer functions, which relate to easily measured soil properties. We measured in urbanized soils by double-ring infiltrometer ( ), near-saturated tension infiltrometry ( ), and constant head borehole permeametry ( ), along with other soil properties across the major soil orders in 12 United States cities.

Urbanization drives convergence in soil profile texture and carbon content.

Urban development has driven extensive modification of the global landscape. This shift in land use and land cover alters ecological functioning, and thereby affects sustainable management agendas. Urbanization fundamentally reshapes the soils that underlay landscapes, and throughout the soil profile, extends impacts of urbanization far below the landscape surface.

An analytical approach to ascertain saturation-excess versus infiltration-excess overland flow in urban and reference landscapes.

Uncontrolled overland flow drives flooding, erosion, and contaminant transport, with the severity of these outcomes often amplified in urban areas. In pervious media such as urban soils, overland flow is initiated via either infiltration-excess (where precipitation rate exceeds infiltration capacity) or saturation-excess (when precipitation volume exceeds soil profile storage) mechanisms. These processes call for different management strategies, making it important for municipalities to discern between them.
