Description

CHEMFORM is a DOS-based program which converts geochemical data files into the format read by the U.S. Geological Survey family of models: WATEQ4F, PHREEQE, or NETPATH. These geochemical models require data formatted in a particular order, which typically does not match data storage. CHEMFORM converts geochemical data that are stored in an ASCII file to input files that can be read by these models, without being re-entered by hand. The data may be in any order and format in the original file, as long as they are separated by blanks. The location of each data element in the input file ... continued below

Description

CHEMFORM is a DOS-based program which converts geochemical data files into the format read by the U.S. Geological Survey family of models: WATEQ4F, PHREEQE, or NETPATH. These geochemical models require data formatted in a particular order, which typically does not match data storage. CHEMFORM converts geochemical data that are stored in an ASCII file to input files that can be read by these models, without being re-entered by hand. The data may be in any order and format in the original file, as long as they are separated by blanks. The location of each data element in the input file is entered in CHEMFORM. Any required data that are not present in your file may also be entered. The positions of the data in the input file are saved to be used as defaults for the next run. CHEMFORM runs in two modes. In the first mode, it will read one input file and write one output file. The input file may contain data on multiple lines, and the user will specify both line number and position of each item in CHEMFORM. This mode facilitates the conversion of the input from one model to the format needed by another model. In the second mode, the CHEMFORM input files contains more than one water analysis. All the geochemical data for a given sample are stored on one line, and CHEMFORM writes an output file for each line. This mode is useful when many samples are available for a site in the same format (different monitoring points or samples taken at different times from one monitoring point).
