This valuable new book, with 2 programs on diskettes, will help practitioners in solving groundwater flow and contamination problems by integrating simulation techniques. The reader is expected to have knowledge of hydrogeology, and have access to books on groundwater hydrogeology. Two microcomputer programs, in compiled FORTRAN 77 with source codes for simulating quasi-three-dimensional groundwater flow and contaminant migration, are presented in this book. The numerical and analytical techniques incorporated in these programs are described in detail. Data entry has been simplified so that the user can run the programs without worrying about FORTRAN input file structures and editors. The basic requirements are a monitor, dot-matrix printer, and an IBM-PC or compatible computer running DOS Version 2.1 or compatible. Programs require a full 640K RAM (minus that used by DOS) for their operation.
