USER'S INDEX TO CRREL LAND TREATMENT COMPUTER PROGRAMS AND DATA FILES.

This user's index is a directory for the computer programs and data files developed at CRREL on land treatment of wastewater. The objective of this directory is to allow users to locate and use or request desired programs or data files, to maintain a permanent record of programs and data files developed under the land treatment program, and to assist in technology transfer. Appendix A contains a list of published papers and technical reports related to the computer programs and the data files. The main User File Directory (UFD), which is called 'ALEXIS,' is hierarchically divided into five sub-UFDs named 'EXPER,' 'MODEL,' 'TAPES,' 'UTILITY,' and 'WDBASE. ' These sub-UFDs are further divided as necessary to maintain a logical arrangement of programs and other files within the account. The overall objective of the file structure is to provide easy access to individual programs while assuring that logically unrelated files remain separated.
