7 HANDHELD CALCULATOR ALGORITJillS FOR COASTAL ENGINEERING Report 3 PART I: INTRODUCTION 1 The advent of the handheld programmable calculator has led to the development of numerous programs in various fields of engineering and science Coastal engineering is no exception This report provides three programs to forecast waves in deep and shallow water Two programs use the Joint North Sea Wave Project (JONSWAP) wave forecasting equations for deep and shallow water as presented in the Shore Protection Manual (U S Army Engineer Waterways Experiment Station Coastal Engineering Research Center (CERC), in preparation, 1984) The third program predicts a depth-limited significant wave height using a spectral approach (Vincent 1982, Thompson and Vincent 1983) 2 The three programs presented herein are versions of Reverse Polish Notation (RPN) logic suitable for use on HP-41CV programmable calculators with or without accessory printer Each program is documented, assumptions are briefly described, and references to more detailed presentations of the theory are given 3 Each of the RPN programs incorporates HP-41 compatible-print routines which print and label all input and output parameters The user has only to enter the input parameters and the results are automatically computed and printed Since the printing routines 1ncrease program length by as much as 25 percent, use of a magnetic card for permanent program storage is recommended The print steps do not need to be deleted if a printer is unavailable 4
