EV4012 Water Quality Modelling Syllabus:
EV4012 Water Quality Modelling Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To understand the fundamentals of mathematical models and their importance in water quality modelling, and to impart the skills to use water quality modelling software for surface and groundwater quality modelling.
UNIT I MODELLING INSIGHTS
Engineers and Mathematical models-Water quality models – historical development – different types of models– steps in model development – importance of model building.- calibration and verification of models- finite element, finite difference and finite volume methods.
UNIT II POLLUTANT TRANSPORT
Transport phenomena – advection, diffusion, dispersion- contamination transport in surface and subsurface water – Simple transport models –steady state and time variable solutions- conservation of mass, momentum and energy balance, governing equation for contaminant fate and transport
UNIT III SURFACE WATER QUALITY MODELLING
Water quality modeling of streams, lakes and estuaries – water quality– model sensitivity – assessing model performance; Models for dissolved oxygen, pathogens and BOD-Streeter Phelp’s model for point and distributed sources – modified streeter Phelp’s equations. Tropic status assessment.
UNIT IV GROUNDWATER QUALITY MODELLING
Groundwater flow and mass transport of solutes – groundwater quality modelling using numerical methods – degradation of organic compounds in sub surface – prediction of contaminant transport and particle tracking -seawater intrusion – basic concepts and modelling.
UNIT V WATER QUALITY MODELLING SOFTWARE
Exposure to surface water and groundwater quality modelling software’s – MIKE 21, WASP, QUAL2E and MODFLOW – demonstration – case studies.
