Using Fractals to Approximate Real River Beds, a talk by Elysia Barker (Manchester Metropolitan University)
Abstract
Brownian Motion is similar to diffusion in a sense that particle movements are independent of one another. Fractional Brownian Motion is a generalisation of Brownian Motion where the particles need not be independent and form a trend. Using this as an advantage, Fractional Brownian Motion can be used to generate bed topography which closely resembles the real world. A method is developed to create an efficient bed topography generator for simulations over fluids to assist in simulating over terrain which is difficult to accurately measure.
