Shoaling waves simulator

There is substantial current interest in the use of remotely sensed images to determine bottom topography in littoral regions.Testing the accuracy of methods used to process the images requires a knowledge of the actual bottom topography at many points in the images.Such knowledge is not available for most littoral regions.Consequently we have developed a. simulator which produces a time series of images showing sea surface elevation for waves moving over a specified piecewise linear bottom of moderate slope.Tests show the simulator is accurate over a range of bottom slopes and reproduces linear phenomena well.Hence processing and analysis methods used successfully on images produced by the simulator may be confidently extended to images where bottom topography is incompletely known, In addition, the simulator can provide controlled datasets for other studies of oceanic processes in the littoral areas.
