On the performance of capillary barriers as landfill cover
soil cover landfill cover capillary barriers
2009/6/8
Landfills and waste heaps require an engineered surface cover upon closure. The capping system can vary from a simple soil cover to multiple layers of earth and geosynthetic materials. Conventional de...
Translating environmental xenobiotic fate models across scales
xenobiotics deterministic models
2009/6/8
The classical models developed for degradation and transport of xenobiotics have been derived with the assumption of homogeneous environments. Unfortunately, deterministic models function well in the ...
Comparison between field measurements and numerical simulation of steady-state solute transport in a heterogeneous soil profile
field measurements solute transport numerical simulation soil profile
2009/6/8
Field-scale solute dispersion is determined by water flow heterogeneity which results from spatial variability of soil hydraulic properties and soil moisture state. Measured variabilities of soil hyd...
Simulation of water movement and isoproturon behaviour in a heavy clay soil using the MACRO model
water movement heavy clay soil isoproturon behaviour
2009/6/8
In this paper, the dual-porosity MACRO model has been used to investigate methods of reducing leaching of isoproturon from a structured heavy clay soil. The MACRO model was applied to a pesticide leac...
