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...
Integrated Modelling of Runoff,Alkalinity,and pH on a Daily Basis
Integrated Modelling Runoff Alkalinity Daily Basis
2009/10/27
Based on the experience from runoff and groundwater recharge simulation a
model system has been developed for terrestrial, hydrochemical, and hydrological
simulations. The system emphasizes the role...
Environmental Impacts of an Old Mine Tailings Deposit—Modelling of Water Balance,Alkalinity and pH
Environmental Impacts Old Mine Tailings Deposit Water Balance
2009/10/27
A diversity of hydrological and hydrochemical data is the foundation for an
integrated modelling study of a leaching tailing deposit at Bersbo in southern
Sweden. A distributed conceptual water bala...
Modelling the Effects of Acid Deposition:Estimation of Long-Term Water Quality Responses in Forested Catchments in Finland
Acid Deposition Long-Term Water Quality Responses Forested Catchments
2009/10/27
A modelling study has been undertaken to investigate long-term changes in
surface water quality in two contrasting forested catchments; Yli-Knuutila, with
high concentrations of base cations and sul...
Modelling the Effects of Acid Sulphate Soils on River Acidity in Finland
Effects of Acid Sulphate Soils River Acidity
2009/10/26
Acid sulphate (AS) soils cover extensive areas of the coastal plains in western
Finland. These soils constitute an environmental hazard due to their ability to
relcase acidity when exposed to atmosp...
High-resolution satellite-based cloud-coupled estimates of total downwelling surface radiation for hydrologic modelling applications
total downwelling surface radiative fluxes hydrologic modelling
2009/7/22
A relatively simple satellite-based radiation model yielding high-resolution (in space and time) downwelling longwave and shortwave radiative fluxes at the Earth's surface is presented. The primary a...
Modelling the ecosystem effects of nitrogen deposition：Model of Ecosystem Retention and Loss of Inorganic Nitrogen
nitrogen deposition Ecosystem Retention
2009/6/8
A catchment-scale mass-balance model of linked carbon and nitrogen cycling in ecosystems has been developed for simulating leaching losses of inorganic nitrogen. The model (MERLIN) considers linked bi...
Modelling regional response of lakewater chemistry to changes in acidic deposition：the MAGIC model applied to lake surveys in southernmost Norway 1974-1986-1995
acid neutralizing capacity acidic deposition lakewater chemistry
2009/6/5
Two methods for modelling regional responses of lake water quality to changes in acidic deposition in southernmost Norway were examined. Both methods are based upon the MAGIC model but differ in mode ...
Regional modelling of acidification in Wales：calibration of a spatially distributed model incorporating land use change
Wales acid neutralising capacity Model of Acidification of Groundwater In Catchments
2009/6/5
The Model of Acidification of Groundwater In Catchments (MAGIC) has been calibrated to 94 catchments in Wales, enabling the quantification of regional response to reduced emissions under the second s...
