An extract from Coastal Engineering Technical Aid No. 83-9, Hand-Held Calculator Algorithms for Coastal Engineering; Report 3, USA-CoE, Coastal Engineering Research Center, CETA 83-9, December 1983, 29 pages

"  ABSTRACT
      This is the third in a series of reports providing handheld calculator
algorithms for use in coastal engineering. The first and second reports in
this series were published as Coastal Engineering Technical Aids (CETA's) and
are available from the U.S. Army Engineer Waterways Experiment Station Tech-
nical Report Distribution Center, Vicksburg, Miss. Of these, CETA 82-1 pre-
sents a set of six algorithms for programs useful in performing certain wave
transformation and wave generation calculations with both the Texas Instru-
ments TI-59 (Algebraic Operating System (AOS) notation) and the Hewlett-
Packard HP-67 (Reverse Polish Notation (RPN)); CETA 82-4 presents the same six
algorithms for use on the HP-41CV (RPN).
      The present report provides algorithms for three calculator programs
that forecast gravity water waves in deep and shallow water. Two programs use
the Joint North Sea Wave Project (JONSWAP) shallow- and deepwater wave fore-
casting equations as presented in the Coastal Engineering Research Center's
Shore Protection Manual (revised edition to be published in 1984). The third
program uses equations to predict a depth-limited significant wave height.
The programs are intended for use with the HP-41CV.
