Java Applets for Coastal Engineering

Introduction

This page is a listing of Java applets that might prove of use in coastal engineering. To run these applets, you only need a web browser that supports Java, such as Netscape 3.01/4.0.

The applets take a while to download and run, so be a little patient. Educators: find out how to install these applets locally on your Java-equipped computer and avoid download times, by writing me.

Use these for engineering purposes at your own risk! These applets are copyrighted University of Delaware.

Applets

• Hydrodynamics
• Wave Calculator: Using incident deep water wave data, it calculates the local wave variables in shallower water. It includes solving the dispersion relationship and Snell's Law.
  Last Change: Code Oct 29, 1997; HTML Oct 29, 1997.

• Linear Wave Kinematics: Given wave properties, the orbital motions of the water particles are shown graphically.
  Last Change: Code Dec 7, 1998; HTML Dec 11, 1996.

• Superposition of Waves: Up to four waves can be superimposed to show wave groups and standing waves.
  Last Change: Code: Mar 17, 1997; HTML Mar 14, 1997.

• Wavemaker Theory: Depending on the type of wavemaker being used (piston or flap), the stroke and power necessary to generate a wave in a given depth of water is determined.
  Last Change: Code Oct 20, 1997; HTML Aug 20, 1998.

• Dual Flap Wavemaker: The behavior of a dual flap wavemaker is shown and the stroke and mean power to generate given waves is shown.
