Simulation of River Flow using GIS Data

Abstract

The major project titled "Simulation of river flow using GIS data" is mainly for the developing a new algorithm for simulation of river flow using various fundamentals of fluid dynamics. The river owing through South Gujarat, INDIA has used to test the model. Fluid flow of river has been simulated using various fundamentals of Computational Fluid Dynamics (CFD) and GIS data. The entire work is divided into three major parts. First task is to acquire GIS (Geometric Information System) data which is in the form of cross-section of the river at intervals of 5 kms and compute the flow using physics formulae. Secondly, the discretization of model using finite- difference method and Finally visualization of the result by images which gives some realistic view of an river flow. River water flow is considered as Gradually Varied Flow (GVF). Manning equations and other fundamental equations are used for modeling the fluid flow of the river. Water discharge at particular cross section is consider as an initial condition for algorithm. The entire algorithm for GVF (open channel) gives variation in height of water surface, width, velocity and area at particular cross-section at desired interval of time.
