Microbial transport in soil caused by surface and subsurface drip irrigation with treated wastewater
bacteriophage fecal coliforms irrigation soil wastewater
2008/11/26
The objective of this work was to compare and simulate transport and fate of microorganisms from wastewater for surface and subsurface irrigation methods. Adsorption isotherms and water-content depend...
Concurrent transport of reactive and non-reactive ions in undisturbed soil columns
transport reactive and non-reactive ions soil
2008/11/26
Advective-dispersive contaminant transport in soils continues to be a subject of extensive studies. Transport of conservative tracers, ie non-reactive ions, is mostly affected by soil physical heterog...
Effect of solid phase wettability on water transport and retention in peat enriched soil affected by freezing/thawing
wettability water retention freezing/thawing soil
2008/11/20
Samples of A and B horizons of arable loessial soil, with and without the addition of c.a. 9% of peat and subjected to six freezing/thawing cycles, were studied. Surface free energies and water contac...
Radioactive tracer techniques used in solute transport studies in a field soil
tracer techniques solute velocity longitudinal dispersion coefficient bypassing ratio
2008/11/12
Radioactive tracer techniques were used for in-situ measurements of the solute velocity, longitudinal dispersion coefficient, and bypassing ratio, as well as for estimation of the impact of land-use c...
Transport of manure-borne Cryptosporidium parvum oocysts through saturatedand unsaturated soil columns
Cryptosporidium parvum soil water transport
2008/11/11
Release of manure-borne Cryptosporidium parvum oocysts is the most probable cause of ground and surface water contamination with this pathogen. Our objective was to assess the effect of water saturati...
Wind-caused air transport through greenhouse screens: a physical modelling approach
air exchange porous screen greenhouse wind pressure physical model
2008/11/10
An understanding of the air exchange through screens is needed to optimise climate control strategies in greenhouses. An analysis of the airflow through porous screens due to wind pressure was perform...
