Applied Environmental Systems Modeling

The book introduces essential concepts of pollutant fate and transport using hands-on model building approach. The first part of the book provides a refresher on pertinent theory with special emphasis on obtaining fluxes and mass-loadings for various physical, chemical and biological processes in natural and engineered systems which are part of the mass-balance formulation. The second part of the book deals with mathematical and numerical approaches for solving mass-balance expressions. A wide range of techniques including the numerical differentiation of ordinary and partial differential equations are discussed. The implementation of these methods on Microsoft Excelr spreadsheet is detailed in a workbook format using diagrams and screenshots.The book is intended to serve as a text/workbook for an introductory fate and transport modeling class offered to advanced undergraduates and early graduate students. In addition, it can also be used as a supplemental text for courses in environmental transport processes and process dynamics. It should also appeal to self-learning environmental engineering practitioners.
