Four computer simulation models are discussed. 1 A stochastic delta model employing a constrained random walk technique was found to be unsatisfactory. 2 A deterministic delta model employing a jet velocity field produces a delta narrow in plan view and sloping away from the source at angles less than 1 degree. Incorporation of a feedback regulator permits a mouth bar and subaqueous levees to build. 3 A beach model incorporating wave refraction and turbulent diffusion of sediment is outlined. 4 A simple sedimentary basin model permits experimentation with sedimentation and subsidence rates and dispersal of sediment by wave action. A computerized bibliography on systems and simulation techniques relevant to geology has been set up, and now contains about 500 literature citations, each with keywords. Retrieval on the basis of selection criteria keywords, title words, author and date can be carried out using programs developed by the SPIRES system at Stanford. The framework for a general synthesis of simulation techniques as applied to geology, and sedimentation in particular, is laid out. Author
