This reference gets you up to speed on mathematical modeling for environmental and water resources management. With a practical, application-oriented approach, it discusses hydrodynamics, sediment processes, toxic fate and transport, and water quality and eutrophication in rivers, lakes, estuaries, and coastal waters. A companion CD-ROM includes a modeling package and electronic files of numerical models, case studies, and model results. This is a core reference for water quality professionals and an excellent text for graduate students.
