The structure and capabilities of a user-friendly, interactive computer program developed for the stability analysis of dikes (GARDS) are described. The GARDS program is designed to guide a geotechnical non-specialist (EPA regulatory personnel) through the customary steps of earth dike analysis considering slope stability, settlement, liquefaction, hydraulic flow and pressure conditions, and piping. The GARDS package is designed for use on the IBM-PC/XT microcomputer. User documentation consists of a combined Handbook/User's Manual (under development) which presents basic theory, program operational procedures, and example long hand and computer solutions for each analysis...Software Description: The program is written in the FORTRAN program language for implementation on an IBM-PC AT, XT or compatible microcomputer using a DOS 2.1 or higher operating system. 512K bytes of core storage are required. Note: A hard disk is required; a color monitor is recommended.
