Soil micromorphology use for modeling of a non-equilibrium water and solute movement
نویسنده
چکیده
Soil micromorphology was applied to specify flow domains in different soils and to select a suitable numerical model for simulation of water flow and herbicide transport. Pore structure detected on soil micromorphological images represented in all cases domains of prevailing water flow and solute transport. Depending on pore configuration and boundary conditions either water immobilization or preferential flow was observed and simulated. The benefits and limitations of the soil micromorphology imaging are discussed and compared with the more often used X-ray computer tomography, magnetic resonance imaging and dye tracer imaging.

Estimation of unsaturated soil hydraulic and solute transport properties by Inverse modeling has thus far been limited mostly to analyses of one-dimensional experiments in the laboratory, often assuming steady-state conditions. This is partly because of the high cost and difficulties in accurately measuring and collecting adequate field-scale data sets, and partly because of difficulties in des...
متن کاملModeling flow and transport in a two-dimensional dual-permeability system with spatially variable hydraulic properties
Most field soils exhibit soil spatial variability as well as soil structure. The challenge is to account adequately for both types of spatial heterogeneity in simulation models. A numerical finite element code was used to compare singleand dual-permeability approaches for modeling variably saturated flow and transport in two-dimensional heterogeneous soil systems. The code was based on the Rich...

متن کاملModeling of Heavy Metal Movement in Vegetated, Unsaturated Soils with Emphasis on Geochemistry
In recent years, researchers have focused on modeling of multicomponent reactive transport and have developed models to study the mobility of potentially toxic heavy metals in the subsurface. In this study, a mathematical model for understanding the fate of a typical heavy metal (lead) in unsaturated soil is developed. The entire modeling activity comprises of three parts. During the first part...
متن کاملNumerical Modeling of Water Flow and Contaminant (Nitrates) Transport in Agriculture: Review
Water movement in soils is a key process that aff ects water quantity and quality in the environment. Movement of contaminants in soils is closely linked with the soil water fl ux and it is very important to properly evaluate these processes that occur in vadose zone. With development of new technologies more attention is dedicated to the use of numerical models to assess water fl ow behavior a...
