Numerical Modelling of Contaminant Transport Hydrodynamics
runoff contamination environment numerical modelling real-time simulation forecasting hydrodynamic management
2015/8/14
Modelling of contaminant transport on watersheds is a problem of concern with regard to the protection of water ecosystems. This paper presents a numerical model, using the finite element method, to s...
Ensemble modelling of nitrogen fluxes: data fusion for a Swedish meso-scale catchment
Ensemble modelling nitrogen fluxes data fusion
2010/12/22
Model predictions of biogeochemical fluxes at the landscape scale are highly uncertain, both with respect to stochastic (parameter) and structural uncertainty. In this study 5 different models (LASCAM...
Modelling field scale water partitioning using on-site observations in sub-Saharan rainfed agriculture
field scale water partitioning on-site observations sub-Saharan rainfed agriculture
2010/4/7
Smallholder rainfed farming systems generally realise sub-optimal crop yields which are largely attributed to dry spell occurrences during crop growth stages. However, through the introduction of appr...
Modelling the inorganic nitrogen behaviour in a small Mediterranean forested catchment,Fuirosos (Catalonia)
inorganic nitrogen behaviour Mediterranean forested catchment Fuirosos
2010/2/20
The aim of this work was to couple a nitrogen (N) sub-model to already existent hydrological lumped (LU4-N) and semi-distributed (LU4-R-N and SD4-R-N) conceptual models, to improve our understanding o...
Modelling disinfection by-products in contact tanks
Modelling disinfection by-products contact tanks
2009/12/7
Numerical modelling has been extensively used in the field of environmental engineering as an efficient method for predicting the fate of contaminants. For chlorine disinfection contact tanks, current...
Rainfall-runoff modelling using adaptive neuro-fuzzy systems
Rainfall-runoff modelling adaptive neuro-fuzzy systems
2009/12/4
Two important applications of rainfall-runoff models are forecasting and simulation. At present, rainfall-runoff models based on artificial intelligence methods are built basically for short-term fore...
Vision statement on open architecture for hydraulic modelling software tools
Vision statement open architecture hydraulic modelling software tools
2009/12/4
This paper identifies the philosophy of open architecture as a feasible vision capable of transforming modelling software packages into living products. This vision, invoked within the specific contex...
WatSup model:a high resolution water supply modelling system
WatSup model high resolution water supply modelling system
2009/12/4
The WatSup™ (Watsup Model Systems Ltd) model is a high resolution model of dendritic water supply networks formed by interconnected modules. Each module, e.g. a house, office, etc, can have mult...
The distribution of precipitation in time during storms constitutes a complex
stochastic process. Mathematical modelling of the process is quite difficult.
The process is conceived as a finite-durat...
Stochastic Modelling of Monthly Streamflow in the Federal Republic of Germany
Stochastic Modelling Monthly Streamflow Federal Republic of Germany
2009/10/29
Monthly streamflow series from five catchment areas, representative of some of
the typical types encounted in Germany,.are analysed. The time series structure
of the streamflow can be described by a...
Measuring and Modelling Snowmelt in Dyrdalen,Western Norway,1979 and 1980
Measuring Modelling Snowmelt Dyrdalen
2009/10/28
During spring snowmelt 1979 and 1980 the runoff from the snowpack was
recorded by lysimetry from a 9 mZ area. Wind speed, air temperature, air
humidity, radiation, and precipitation data were also r...
A Mathematical Modelling System for Flood Forecasting
Mathematical Modelling System Flood Forecasting
2009/10/28
In this paper comprehensive simulation models are presented which can forecast
the streamflow in real time at various points in river systems and provide a
tool for identifying improvements of the r...

Water Exchange Transit Times Till Basins Oxygen-18
2009/10/27
The application of hydrological models to data on conservative tracers can
yield information about transit times and storage volumes and may provide an
independent test of the model structure.In thi...
A stochastic solute transport model is applied to a groundwater contamination
case. The contamination is caused by leachate from an unprotected landfill
situated in a highly-permeable unconfined aqu...
