Pre-plant application of toxic fumigants to soil beds covered by plastic film is commonly used in agriculture to control soil-borne pathogens. Plastic mulch covers tend to physically suppress the emissive loss of gaseous fumigant to the atmosphere. W

Temperature dependence of selected parameters was defined and illustrated. The order of sensitivity among tested model parameters (sorption coefficient, KD; diffusion coefficient, Dg; vapor pressure, P; degradation rate, k; Henry’s constant, H) was
Adaptive Grid Refinement in Numerical Models for Water Flow and Chemical Transport in Soil: A Review

Vadose Zone Journal. 1:222-238
Insufficient spatial or temporal resolution is a common source of errors in numerical solutions for both water flow and solute transport in the variably unsaturated vadose zone. Evaporation near the surface, as well as infiltration into initially dry

Contamination of groundwater resources by non-aqueous phase liquids (NAPLs) has become an issue of increasing environmental concern. This study investigated the formation and flow of microemulsions during surfactant flushing of NAPL-contaminated soil

In situ pumping of micellular solutions of surfactant (S) and cosurfactant (CoS) in water (W) through contaminated soils or aquifers offers potential for enhanced remediation of residual nonaqueous‐phase liquids (NAPLs). Extremely low interfacial t

Ample published evidence demonstrates that colloidal particles can act as carriers to enhance the transport of contaminants in subsurface environments. Conventionally, soil and aquifer porous media are considered to have two phases: an immobile solid

Sorbent-sorbate interactions heavily retard the movement of P during water flow in most soils. The effect of soil/solution ratio on sorption kinetics and movement of P during unsteady unsaturated water flow were investigated. A series of batch experi

Deposition of P-laden dairy waste onto acid, sandy Spodosols located in the Lake Ocheechobee Basin in south Florida is commonly recognized to increase levels of P in soil profiles, groundwater, and local streamflow. In the soil profile, P accumulatio
