Estimating land-use change impacts on direct runoff and non-point source pollutant loads in the Richland Creek basin (Illinois, USA) by applying the L-THIA model
land-use change runoff non-point source pollution
2015/1/7
An export coefficient approach to hydrological and non-point source (NPS) pollution modeling enables quick and simple assessment of long-term impacts for planning purposes. An export coefficient and g...
Confirmation of ACRU model results for applications in land use and climate change studies
ACRU model results applications climate change studies
2010/12/22
The hydrological responses of a catchment are sensitive to, and strongly coupled to, land use and climate, and changes thereof. The hydrological responses to the impacts of changing land use and clima...
Parameterization of a coupled CO2 and H2O gas exchange model at the leaf scale of Populus euphratica
Parameterization coupled CO2 and H2O gas exchange model leaf scale Populus euphratica
2010/4/7
The following two models were combined to simultaneously predict CO2 and H2O gas exchange at the leaf scale of Populus euphratica: a Farquhar et al. type biochemical sub-model of photosynthesis (Farqu...
Development of a model for the characterization of fluid dispersion in electrochemical reactors
model for the characterization fluid dispersion electrochemical reactors
2009/12/4
This paper analyses the hydrodynamic behaviour of electrochemical reactors by simulating stimulus–response experiments. The experiments were performed with a simple experimental arrangement to generat...
Sulphur and Oxygen Isotopes Behaviour in Sulphates of Atmospheric Ground water System Observations and Model
Sulphur Oxygen Isotopes Behaviour Atmospheric Ground water System
2009/10/26
Comparison of sulphate concentrations in groundwaters and atmospheric precipitation
suggests that about 30 % of groundwater sulphate may be of atmospheric
origin. Another source of sulphate ion is t...
A Simple Automatic Calibration Routine for the HBV Model
Automatic Calibration Routine HBV Model
2009/10/23
A simple, but efficient, method for automatic calibration of the conceptual HBV
rainfall-runoff model was developed. A new criterion, which combines the com-
monly used efficiency criterion R 2 and ...
A Model for Water Exchange Between the Baltic Sea and the Gulf of Riga
Water Exchange Baltic Sea Gulf of Riga
2009/10/23
A model for water exchange of a basin connected to the open sea by two channels
has been worked out. The model is applied on the Gulf of Riga, where the
water exchange processes versus strong landba...
Estimation of Parameter Uncertainty in the HBV Model
Estimation of Parameter Uncertainty HBV Model
2009/10/23
Usually the HBV model is calibrated by seeking one optimal parameter set that
represents the catchment. From experience we know, however, that it is hardly
poss~ble to find an unique parameter set. ...
Simulation of a Biogeochemical Model in Different Lakes
Simulation Biogeochemical Model Different Lakes
2009/10/22
Eutrophication, caused by nutrients leached from soil and emitted from point
sources, is a well-known problem in many Swedish lakes. There are several
countermeasures that can be used to reduce eutr...
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...
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...
Assessing the model performance of an integrated hydrological and biogeochemical model for discharge and nitrate load predictions
integrated hydrological biogeochemical model
2009/5/7
In this study, we evaluate the performance of the SWAT-N model, a modified version of the widely used SWAT version, for discharge and nitrate predictions at the mesoscale Dill catchment (Germany) for ...
Towards benchmarking an in-stream water quality model
in-stream water quality model general quality assessment
2009/5/6
A method of model evaluation is presented which utilises a comparison with a benchmark model. The proposed benchmarking concept is one that can be applied to many hydrological models but, in this inst...
