Title: Long-term forward hydrologic fluvial system evolution model
Author: Vining, Mark Richard
Abstract: This work presents a computer model of river sediment transport and the morphologic evolution of the river system, on the scale of thousands to millions of years, with the influence of geologic processes. The computer program runs under Windows '95 or 3.x. Code is written in Borland C++ 5.01. Data input is from eight editable files. The code, sample data, and user instructions are provided. The model is a 1-D finite-difference scheme of longterm average flow conditions. The simulation is discretized into time steps, length cells, sediment grain size classes, and fluvial environments within each cell. The cell landscape is composed of three fluvial environments (channel, alluvial ridge, and floodplain) and the watershed drainage area. Time steps are divided into four steadystate domains which characterize short-term variations in discharge. A time dilation procedure characterizes the varying shape of discharge event hydrographs downstream.
