Delta7: A Computer Model of Delta Growth.

Abstract

Delta 7 is an interactive Fortran IV Computer Program written for the PDP-11 mini-computer. It accepts initial beach and river conditions, as well as a varying set of deepwater wave conditions, and produces a data set that outlines a planview of the coastline at specified time intervals. The coastline can subsequently be graphed using the Calcomp 1037 Drum Plotter with the XPLOT instruction of MAGIC. The use of computer simulation technique allows a comparison of the effects of varying the order of wave attacks on a developing river delta, which is supplied a constant amount of sediment per day. The conclusion is that random ordering produces approximately the same delta every time, whereas ordering the waves according to power results in a radical delta. This paper includes sample data, computer program and several graphs.
