Numerical Modelling of Contaminant Transport Hydrodynamics
runoff contamination environment
2015/1/8
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...
Modelling Snow Water Conservation on the Canadian Prairies
Modelling Snow Water Conservation the Canadian Prairies
2014/4/2
Snowcover accumulation has tremendous impacts on Canadian Prairie hydrology and agriculture (Pomeroy and Gray, 1995; Fang and Pomeroy, 2007). Wind redistribution of snow or blowing snow is frequent in...
Spatial uncertainty assessment in modelling reference evapotranspiration at regional scale
evapotranspiration regional scale
2010/12/22
Evapotranspiration is one of the major components of the water balance and has been identified as a key factor in hydrological modelling. For this reason, several methods have been developed to calcul...
Data-based mechanistic modelling and forecasting of hydrological systems
Data-based mechanistic modelling forecasting hydrological systems
2009/12/7
The paper presents a data-driven approach to the modelling and forecasting of hydrological systems based on nonlinear time-series analysis. Time varying parameters are estimated using a combined Kalma...
Linear advection modelling:the issue of divergent flows
Linear advection modelling issue divergent flows
2009/12/7
Schemes for linear advection modelling in multiple dimensions on structured grids use either time-splitting or an unsplit approach for flux computation. In the case of strongly divergent flows, time-s...
Water-quality modelling of the Upper Mersey river system using an object-oriented framework
Water-quality modelling Upper Mersey river system object-oriented framework
2009/12/4
The aim of this paper is to present the recent advances in the development of an object-oriented software system for water-quality management, and discuss the results from its application to the study...
Service reservoirs were built to provide the dual function of balancing supply with demand and provision of adequate head to maintain pressure throughout the distribution network. Changing demographic...
Comparative application of artificial neural networks and genetic algorithms for multivariate time-series modelling of algal blooms in freshwater lakes
Comparative application artificial neural networks genetic algorithms time-series modelling
2009/12/4
The paper compares potentials and achievements of artificial neural networks and genetic algorithms in terms of forecasting and understanding of algal blooms in Lake Kasumigaura (Japan). Despite the c...
This paper deals with modelling and identification of a river system using physical insights about the process, experience of operating the system and information about the system dynamics shown by me...
Modelling is considered to be an inherent part of the design and operation of a wastewater treatment system. The models used in practice range from conceptual models and physical design models (labora...
Sensitivity and uncertainty analysis for river quality modelling
Sensitivity analysis uncertainty analysis river quality modelling
2009/12/4
Uncertainty analysis for model simulation is of growing importance in the field of water quality management. The importance of this concern is provided by recent public awareness over health risks fro...
Identification of support vector machines for runoff modelling
Identification support vector machines runoff modelling
2009/12/4
This paper describes an exploration in using SVM (Support Vector Machine) models, which were initially developed in the Machine Learning community, in flood forecasting, with the focus on the identifi...
A hybrid reasoning system for supporting estuary modelling
Ahybrid reasoning system estuary modelling
2009/12/4
In this paper the development of a Case-Based reasoning system for Estuarine Modelling (CBEM) is presented. The aim of the constructed CBEM system is to facilitate the utilisation of complex modelling...
Testing and modelling autoregressive conditional heteroskedasticity of streamflow processes
autoregressive conditional heteroskedasticity streamflow processes
2009/11/9
Conventional streamflow models operate under the assumption of constant variance or season-dependent variances (e.g. ARMA (AutoRegressive Moving Average) models for deseasonalized streamflow series an...
A two-dimensional horizontal hydrodynamical model has been used to estimate
the changes that a harbour road will cause in the water exchange of an
estuary. The research area has been the Kokemaenjok...
