Effects of Acid Precipitation on a Small Acid Lake in Southern Norway
Acid Precipitation Small Acid Lake Southern Norway
2009/10/29
Langtjern is an acid lake situated in south-central Norway, 516 m above sea level.
The watershed is underlain by biotite gneisses and granites. Coniferous forests
cover 63% of the watershed, while 1...
Studies of the groundwater flow and quality around the lakes Bredvatten and
Lysevatten have shown, that the increased concentrations of aluminum in acid
lake water is caused by acid groundwater, and...
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...
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,...
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...
Seasalt Effects on the Acid Neutralizing Capacity of Streamwaters in Southern Norway
Seasalt Effects Acid Neutralizing Capacity Southern Norway
2009/10/26
Input of neutral salt, primarily NaCI, from sea spray is an important factor for shortterm
acidification of surface water, primarily in already acidified areas, because Na
may substitute for H+ and ...
Acid neutralization capacity measurements in surface and ground waters in the Upper River Severn, Plynlimon:from hydrograph splitting to water flow pathways
Acid Neutralization Capacity water flow pathways hydrograph splitting
2009/6/8
Acid Neutralization Capacity (ANC) data for ephemeral stream and shallow groundwater for the catchments of the upper River Severn show a highly heterogeneous system of within-catchment water flow path...
Effects of summer drought on peat soil solution chemistry in an acid gully mire
dissolved organic carbon flush wetland soil solution chemistry
2009/6/8
In a field experiment to investigate potential impacts of climatic change, a small area of flush wetland in Wales was subjected to three successive years of simulated summer drought/rewetting (autumn...
Stream water quality in acid sensitive UK upland areas:an example of potential water quality remediation based on groundwater manipulation
Stream water quality potential water quality groundwater manipulation
2009/6/8
The patterns of variation in water quality for an acidic stream draining plantation forest overlying acidic and acid sensitive gley soils with shale and slate bedrock changed following the introductio...
A two-layer application of the MAGIC model to predict the effects of land use scenarios and reductions in deposition on acid sensitive soils in the UK
acid soils UK Acid Waters Monitoring Network
2009/6/5
A two-layer application of the catchment-based soil and surface water acidification model, MAGIC, was applied to 21 sites in the UK Acid Waters Monitoring Network (AWAMN), and the results were compare...
Comparison of simulated forest soil response to acid deposition reduction with two models of differing complexity
forest soil \acid deposition reduction
2009/6/5
Great effort has been dedicated to developing soil acidification models for use on different scales. This paper focuses on the changes in model performance of a site scale soil acidification model (NU...
Acid deposition, land-use change and global change:MAGIC 7 model applied to Aber, UK (NITREX project) and Risdalsheia, Norway (RAIN and CLIMEX projects)
Acid deposition MAGIC (version 7) global change
2009/6/5
Nitrogen processes are now included in a new version of MAGIC (version 7), a process-oriented catchment-scale model for simulating runoff chemistry. Net retention of nitrogen (N) is assumed to be cont...
Assessing soil calcium depletion following growth and harvesting of Sitka spruce plantation forestry in the acid sensitive Welsh uplands
soil calcium depletion Welsh uplands plantation forestry
2009/6/5
A simple mass balance has been used to estimate soil calcium depletion during the growth of a 50 year old Sitka spruce crop on acid, base-poor peaty podzol soils in upland Wales. Growth of the crop wi...
