| Summary: | In this research, the phenomena of water flow in an open channel with different
cross-sectional geometries will be investigated. The equation of Saint-Venant
is utilized as the model. On a staggered grid, the model will be numerically
solved using the finite volume method. Prior to using the model to determine
the general trend of the phenomenon of water flow in open channels, the model
is validated using experimental data collected in the laboratory and compared
with the simulation results from the HEC-RAS hydraulics modeling application to
determine the model’s accuracy. This research examines rectangular, trapezoidal,
and irregular cross-sectional forms of the channel. On the premise of the comparisons
performed, it can be stated that the developed model simulates and represents
the phenomena of water flow in an open channel with diverse cross-sectional forms
of the channel pretty effectively. Moreover, if the downstream is closed, there is a
linear connection between the upstream water flow velocity and the average water
level at the conclusion of the experiment. |
