The Influence of Man's Activities in Rivers on Sediment Transport
Influence Man's Activities Sediment Transport
2009/10/29
An attempt to use old semicompiled data on turbidity, transport and deposition
of suspended material is carried out. The influence of different activities is
illustrated. The change of water chemist...
In connection with the 50th anniversary of Aarhus University, 11 September,
1978, brigadier R.A. Bagnold, F.R.S., was conferred the honorary degree of
Doctor of Science. The present paper is the man...
Parametrization of Contaminant Transport through an Anisotropic Unconfined Aquifer
Parametrization Contaminant Transport Anisotropic Unconfined Aquifer
2009/10/28
A duo two-dimensional deterministic model of contaminant transport through
a homogeneous and anisotropic unconfined aquifer is developed. This model
is then utilized to evaluate the effects of such ...
The Application of Radioactive Tracers for Determination of Bed-Load Transport in Alluvial Rivers
Radioactive Tracers Bed-Load Transport Alluvial Rivers
2009/10/28
Radioactive isotopes have been applied for determining the transport rate of
bed load in an alluvial river on the basis of: centroid velocity of the tracer
particles, size and material-transporting ...
Modelling of Solute Transport in the Unsaturated Zone
Modelling Solute Transport Unsaturated Zone
2009/10/28
A numerical model for solute transport in the unsaturated zone has been
developed. The model is based on the basic equation for soil water flow in one
dimension and the general convection-dispersion...
Transport and Chemodynamics of Organic Micropollutants and Ions during Snowmelt
Transport Chemodynamics Organic Micropollutants Ions
2009/10/27
By means of laboratory experiments and field measurements we investigated
the chemodynamics and transport behaviour of organic micropollutants and
inorganic ions in melting snowpacks. Dissolved subs...
This paper presents a review of groundwater models capable of simulating solute transport
(i.e. advection-dispersion) and equilibrium chemistry processes.
Introductory, basic model components are di...
Metal Transport in Groundwater Contaminated by Acid Mine Drainage
Metal Transport Acid Mine Drainage
2009/10/26
Acid mine drainage from a rock dump at an abandoned mine in Dalarna,
Sweden, has contaminated the groundwater and created a leachate plume
characterized by low pH and high concentrations of Fe, SO4,...
Spatial Variability of Contaminant Transport in a Fractured Till,Avedøre Denmark
Spatial Variability Contaminant Transport Fractured Till
2009/10/23
A field experiment shows that rapid downward migration of solutes and microorganisms
can occur in a fractured till. A solute tracer, chloride, and a bacteriophage
tracer, PRD-1, were added to ground...
Internal HBV-96 Variables and Phosphorus Transport Processes
Internal HBV-96 Variables Phosphorus Transport Processes
2009/10/23
The high data requirements of total phosphorus (TP) transport prediction tools
limit their application. Recently, research has therefore started in Sweden to use
a conceptual hydrological model, HBV...
