Simulation of 2D surface flow in open channel using explicit finite difference method
2D surface flow models are useful to understand and predict the flow through breach, over a dyke or over the floodplains. This paper is aimed at the surface flows to study the behavior of flood waves. The open channel water flow in drains and rivers is considered in view of the fact that such f...

| description | 2D surface flow models are useful to understand
and predict the flow through breach, over a dyke or over
the floodplains. This paper is aimed at the surface flows to
study the behavior of flood waves. The open channel water
flow in drains and rivers is considered in view of the fact
that such flows are the source of flash flood. In order to
predict and simulate the flood behavior a mathematical
model with the initial and boundary conditions is
established using 2D Saint-Venant partial differential
equations. Next, the corresponding model is discretized by
using the explicit finite difference method and
implemented on MATLAB. For the testing and
implementation purpose a simple rectangular flow channel
is considered. The output parameters like height or depth
of water, the fluid velocity and the volumetric flow rate are
simulated numerically and visualized for the different time
steps. The initial simulation results are useful to
understand and predict the flood behavior at different
locations of flow channel at specific time steps and can be
helpful in early flood warning systems. |
