Numerical Modelling of Contaminant Transport Hydrodynamics
runoff contamination environment numerical modelling real-time simulation forecasting hydrodynamic management
2015/8/14
Modelling of contaminant transport on watersheds is a problem of concern with regard to the protection of water ecosystems. This paper presents a numerical model, using the finite element method, to s...
Assessment of Spatial Patterns of Sediment Transport and Delivery for Soil and Water Conservation Programs
off-site soil erosion soil erosion deposition model
2015/8/14
Soil erosion has tremendous impacts on most river systems throughout the United States. Such non-point pollution results from land-use and agricultural practices and leads to sedimentation downstream,...

Investigation of a parameter estimation method for contaminant transport in aquifers
Investigation parameter estimation method contaminant transport aquifers
2009/12/4
Real world groundwater aquifers are heterogeneous and system variables are not uniformly distributed across the aquifer. Therefore, in the modelling of the contaminant transport, we need to consider t...
Fuzzy rule-based model for contaminant transport in a natural river channel
Fuzzy rule-based model contaminant transport natural river channel
2009/12/4
Fuzzy rules are used to model solute dispersion in a river dead zone, such that the turbulent diffusion is determined by a fuzzy inference system which relates the local mean velocity shear to the lon...
Dynamic identifiability analysis of the transient storage model for solute transport in rivers
Dynamic identifiability analysis transient storage model solute transport
2009/12/4
The use of dynamic mathematical models to simulate the behaviour of environmental systems is common practice. However, the output of these models remains uncertain, despite their widespread use and lo...
Pollution of underground water-a computational case study using a transport model
Pollution of underground water computational case study transport model
2009/12/4
Damage of the waterproofing system in a waste material depository or sewage sludge composting plant and the penetration of pollutants into the soil and groundwater may cause an environmental mishap. A...
TRANSPORT OF SUSPENDED SOLIDS ALONG THE VISTULA RIVER
TRANSPORT SUSPENDED SOLIDS VISTULA RIVER
2009/10/29
A short description is given of a method for preparing a balance of transported
solids along the Vistula river on the basis of many years' monitoring
and observations of transportation of suspended ...
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...
A Sediment Transport Model for Straight Alluvial Channels
Sediment Transport Model Straight Alluvial Channels
2009/10/29
The paper presents a simple mathematical model for sediment transport in
straight alluvial channels. The model, which is based on physical ideas related to
those introduced by Bagnold (1954), was or...
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 ...

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 ...

2009/10/28
In an earlier investigation of the behaviour of tracer particles for determination
of bed load transport in an alluvial stream (Thomsen 1080), specific
records were taken of the particle velocities ...
