Long-term modelling of nitrogen turnover and critical loads in a forested catchment using the INCA model
forest ecosystem N saturation critical load modelling
2009/3/17
Many forest ecosystems in Central Europe have reached the status of N saturation due to chronically high N deposition. In consequence, the NO3 leaching into ground- and surface waters is often substan...
N fluxes in two nitrogen saturated forested catchments in Germany: dynamics and modelling with INCA
forest ecosystem modelling N budgets N saturation NO3
2009/3/17
The N cycle in forests of the temperate zone in Europe has been changed substantially by the impact of atmospheric N deposition. Here, the fluxes and concentrations of mineral N in throughfall, soil s...
Inverse modelling in estimating soil hydraulic functions: a Genetic Algorithm approach
Genetic Algorithm inverse modelling
2009/3/17
The practical application of simulation models in the field is sometimes hindered by the difficulty of deriving the soil hydraulic properties of the study area. The procedure so-called inverse modelli...
Modelling soil moisture for a grassland and a woodland site in south-east England
Soil moisture model observation field capacity
2009/3/17
This paper describes a comparison between two soil moisture prediction models. One is MORECS (Met Office Rainfall and Evaporation Calculation Scheme), the Met Office soil moisture model that is used b...
Modelling floods in the Ammer catchment: limitations and challenges with a coupled meteo-hydrological model approach
RAPHAEL modelling forecasting model coupling
2009/3/12
Numerous applications of hydrological models have shown their capability to simulate hydrological processes with a reasonable degree of certainty. For flood modelling, the quality of precipitation dat...
The effect of changes in natural and anthropogenic deposition on modelling recovery from acidification
climate change dynamic modelling run-off chemistry
2009/3/12
The multi-layer dynamic soil chemistry SAFE model was used to study the dynamics of recovery in the F1 catchment at Lake Gårdsjön, Sweden.
Reduction of Monte-Carlo simulation runs for uncertainty estimation in hydrological modelling
parameters calibration GLUE Monte-Carlo simulation
2009/3/12
Monte-Carlo (MC) simulation based techniques are often applied for the estimation of uncertainties in hydrological models due to uncertain parameters. One such technique is the Generalised Likelihood ...
Modelling sulphate stream concentrations in the Black Forest catchments Schluchsee and Villingen
sulphate release organic S mineralisation
2009/3/12
The sulphate (SO4) released by mineralisation and desorption from soil can play an important role in determining concentrations of SO4 in streams. The MAGIC model was calibrated for two catchments in ...
Modelling the effects of atmospheric sulphur and nitrogen deposition on selected lakes and streams of the Central Alps (Italy)
MAGIC northern Italy acidification recovery nitrogen
2009/3/12
The dynamic model MAGIC was calibrated and applied to selected sites in north-western Italy (3 rivers, 10 alpine lakes) to predict the future response of surface water to different scenarios of atmos...
Modelling long-term changes in stream water and soil chemistry in catchments with contrasting vulnerability to acidification (Lysina and Pluhuv Bor, Czech Republic)
MAGIC model catchment critical loads Gothenburg Protocol
2009/3/12
In two Czech catchments covered by Norway spruce forests, the MAGIC model was used to simulate annual stream water and soil chemistry for the period 1851–2030. These two sites represent geochemical en...
Modelling reversibility of central European mountain lakes from acidification: Part II – the Tatra Mountains
MAGIC atmospheric deposition sulphate
2009/3/12
A dynamic, process-based model of surface water acidification, MAGIC7, has been applied to four representative alpine lakes in the Tatra Mountains (Slovakia and Poland). The model was calibrated for a...
Modelling reversibility of Central European mountain lakes from acidification: Part I - the Bohemian forest
MAGIC atmospheric deposition N retention
2009/3/12
A dynamic, process-based acidification model, MAGIC7, has been applied to three small, strongly acidified lakes in the Bohemian Forest, the Czech Republic. The model was calibrated for a set of experi...
Modelling the recovery of acid-sensitive Finnish headwater lakes under present emission reduction agreements
acidification lake catchment recovery SMART model Finland
2009/3/12
Over the past two decades, substantial reductions in the deposition of acidifying substances (primarily sulphur) have occurred in most parts of Europe and, following recent agreements, this trend is l...
A modelling assessment of acidification and recovery of European surface waters
Europe acid-sensitive waters predictions
2009/3/12
The increase in emission of sulphur oxides and nitrogen (both oxidised and reduced forms) since the mid-1800s caused a severe decline in pH and ANC in acid-sensitive surface waters across Europe. Sinc...
