213 Connections - the Role of Connectivity In Soil Processes: I

Oral Session
S01 Soil Physics

When modeling flow and transport processes, soils are often viewed as random heterogeneous media. But, soil forming processes are more likely to lead to spatially connected pathways. This oral session examines modeling, laboratory, and field investigations into the influence of connected pathways on flow and transport in soils on scales from root holes, to fractures, to buried channels.
