Tidal current analysis procedures and associated computer programs

Although a standardized procedure has developed for analyzing water level data to obtain the parameters required to produce the NOS Tide Tables, there has not been such a procedure developed for tidal currents. This publication sets forth a suggested step-by-step procedure to follow for obtaining the parameters needed to produce the NOS Tidal Current Tables. This is followed by detailed explanations of each of the computer programs used. These sections are designed to be stand-alone user’s guides for each of the programs, giving a complete explanation of how the calculations are carried out, options to be set by the user, and sample input and output files. Table A indicates the inputs and outputs for the major programs used in the analysis of tidal currents. All the programs are written in FORTRAN.
