Assessment of the Impact pf Mining on Agricultural Land using Erosion-Deposition Model and Space Borne Multispectral Data
Mining Agricultural Land Erosion-Deposition Model Space Borne Multispectral Data
2015/8/6
Since erosion of mine overburden and mine dump leads to its deposition down the slope in the catchment, an attempt was made to study the erosion-deposition pattern in a micro watershed in part of Goa ...
Analysis of Mercury Concentrations in Indiana Soil to Evaluate Patterns of Long-Term Atmospheric Mercury Deposition
atmospheric deposition mercury emission soil mercury concentration
2015/1/16
Mercury (Hg) has proven to be a risk to the public, mainly through the consumption of fish. Because of this, many fish consumption advisories have been issued in Indiana. Although much is known about ...

Erosion-Deposition Model Space Borne Multispectral Data
2015/1/4
Since erosion of mine overburden and mine dump leads to its deposition down the slope in the catchment, an attempt was made to study the erosion-deposition pattern in a micro watershed in part of Goa ...
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 Erosion and Deposition of Cohesive Sediments from Hay River,Northwest Territories,Canada
Modelling Erosion Cohesive Sediments Hay River
2009/10/22
A large volume sample of river-bed cohesive sediment and water from Hay
River, Northwest Territories, Canada was collected during a spring field program
in 2000 as part of a study on under-ice movem...
Hydraulic Modelling of Suspended Sediment Deposition in an Inundated Floodplain of the Nemunas Delta
Hydraulic Modelling Suspended Sediment Deposition Nemunas Delta
2009/10/22
Floods of meadows in the delta of the river Nemunas contribute to the deposition
and retention of sediments and nutrient that would otherwise deposit in the
Curonian Lagoon. In grassland area of the...
Acidification in Three Lake District Tarns：Historical Iong term trends and modelled future behaviour under changing sulphate and nitrate deposition
Acidification nitrate deposition sulphate
2009/6/8
Three upland Lake District Tarns, Scoat, Greendale and Burnmoor, have been evaluated using MAGIC (Model of Acidification of Groundwater In Catchments) to reconstruct past, present and future chemical ...
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 ...
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...
Modelling the response of soil and runoff chemistry to forest harvesting in a low deposition area (Kangasvaara, eastern Finland)
soil runoff chemistry low deposition area maximum feasible reduction
2009/6/5
A simple dynamic soil model developed to analyse the effects of atmospheric deposition and nutrient cycling on terrestrial ecosystems, SMART 2, was applied to the Kangasvaara catchment in eastern Finl...
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...
Modelling the response of soil and soil solution chemistry upon roofing a forest in an area with high nitrogen deposition
nitrate (NO3) sulphate (SO4) soil solution chemistry
2009/6/5
In the Speuld forest, the Netherlands, the dynamic soil acidification model NuCSAM has been applied to a manipulation experiment in which part of the forest was roofed to control nitrogen (N) and sulp...
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...
Comparison of mercury in atmospheric deposition and in Illinois and USA soils

2009/5/18
It has been reported that most mercury (Hg) in USA soils is from atmospheric Hg deposition, mostly from anthropogenic sources. This paper compares the rates of atmospheric Hg deposition to amounts of ...
