(HP-67/97) Coastal Engineering Technical Aid No. 82-1 (1)
An extract from Coastal Engineering Technical Aid No. 82-1, Hand-Held Calculator Algorithms for Coastal Engineering, USA-CoE, Coastal Engineering Research Center, CETA 82-1, January 1982, 71 pages

"   ABSTRACT
   This report provides algorithms for a number of calculator programs useful
in performing coastal engineering calculations, primarily in the area of wave
transformations and wave generation. Six programs are included with different
versions for use with hand-held calculators which employ either the Reverse
Polish Notation (RPN) or the Algebraic Operating System (AOS) . These programs
can be used to compute linear wave parameters, orbital velocities, breaking
wave height and direction, shallow-water wave forecasts, depth-limited breaking
wave height, and wave transmission past a vertical barrier.

I. INTRODUCTION

   Since subtle differences exist among various brands of calculators and
among various models by the same manufacturer, the programs presented may need
to be modified to adapt them to other brands or models. These programs were
prepared and checked, using the Texas Instruments TI-59 (AOS) and the Hewlett-
Packard HP67 (RPN) …
