CE3041 Water Quality and Management Syllabus – Anna University Regulation 2021

COURSE 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 qualitymodelling.

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 POLLUTION 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 COD, BOD-Streeter Phelp’s model for point and distributed sources – modified streeter Phelp’s equations.

UNIT IV GROUNDWATER QUALITY MODELLING

Groundwater flow and mass transport of solutes – groundwater quality modelling using numerical methods – Parameters, Input-output stresses, Initial and Boundary conditions- degradation of organic compounds in subsurface – Model calibration : steady state and unsteady state – sensitivity analysis – Model validation –seawater intrusion – basic concepts and modelling.

UNIT V WATER QUALITY MANAGEMENT MODELS

Exposure to surface water and groundwater quality modelling software’s – MIKE 21, WASP, QUAL2E and MODFLOW – demonstration – case studies – Modeling multilayer groundwater flow system – Artificial recharge feasibility through modeling – Groundwater contamination, restoration and management.
