SPITSYM, A FORTRAN IV Computer Program for Spit Simulation

The development and operation of a program to simulate the formation of a shingle spit is described. This includes a detailed account of action of the subroutines that simulate the four major processes that are thought to act on the spit. The simulation relies on stochastic techniques and the program is concerned with building a spit in a 50-row by 60-column matrix so that the results of the process are graphically displayed. The example illustrating use of the program is the Hurst Castle spit on the Hampshire coast of England.
