CE6480 : Contaminant Transport Modelling copy 2

Introduction: Transport phenomenon, diffusion, dispersion, advection, adsorption, conservative and nonconservative pollutants, sources and sinkspoint and non-point. Governing Equations for flow and transport in surface and subsurface waters, chemical and biological process models, simplified models for lakes, streams, and estuaries. Model complexity: Selection and development, model resolution, coupled and uncoupled models, linear and nonlinear models, solution techniques, data requirements for calibration, application and evaluation of environmental control, bio-remediation. Numerical models: FDM, FEM and Finite volume techniques, explicit vs. implicit methods, numerical errors, and stability. High resolution techniques. Stream quality modelling using QUAL2E Groundwater transport modelling using SUTRA.
