表状态

Integration of pedotransfer functions and topographical data to obtain soil hydraulic properties at input data, especially the parameters that describe the hydrologic behavior of soils. Traditional methods to determine soil hydraulic parameters at large scales are time-consuming and very costly. To carry out a soil hydraulic characterization in a cost-effective way, pedotransfer functions (PTFs) a

Analytical Model for Gravity-Driven Drainagelocal (typically laboratory) scale. These results are then specified by adopting the Brooks et al (1964) model for the hydraulic conductivity curve. At field scale, we combine our analytical results with the stream tube model of Dagan et al. (1979) to derive the ensemble average of the effective sat

Hydrogeophysical characterization of subsurface solute transport at the Krauthausen test site: experrive hydraulic variables (e.g. velocity) and solute transport parameters (e.g. dispersivity) in subsurface environments. For this purpose, real tracer experiments were monitored using crosshole time-lapse ERT at reference planes at the Krauthausen test site. Numerical inversion of an ERT dataset obt

Biogeochemical modeling of reactive transport applied to laboratory and field studies on jet-fuel con acceptors and inhibitors. In this way, PHREEQC will simulate the redox processes under concern both with regard to kinetics and thermodynamics. Furthermore, PHREEQC allows one-dimensional reactive transport to be simulated..The biogeochemical processes involved in transport and biodegradation of d

correct and complete numerical approach in order to reach the best results at the lowest possible cost. The authors focus on the improvement of the scientific base for the development of integrated indicators of the environmental risks created by the presence of pollutants in water and porous media

HARD

Enhancement of solute spreading in soils due to particle-facilitated transport and preferential flow(preferential flow) or lower accessibility (particle-facilitated transport). Model predictions account for the amount and the velocity of preferential flow as well as the potentially kinetic interaction between organic contaminant and mobile particles.
