| Zusammenfassung |
| Numerical models utilizing the dual-continuum concept have become useful tools for modeling flow and transport in structured soils with significant preferential flow effects. These models are based on the separation of the soil matrix and preferential flow domains and the replacement of the complex interactions between the two domains by simple transfer formulae.
This presentation focuses on: (i) the basic assumptions of the dual-continuum approach, especially the interpretation of parameters controlling the interdomain transfer of water [1], solute and heat; (ii) the application of the dual-continuum model S1D to numerical analysis of soil water dynamics in a shallow hillslope soil under natural vegetation, involving transport of a natural tracer [2] and transport of heat.
