| Summary: | In this research, we investigate dambreak phenomenon using the shallow water
equation that is derived from the mass conservation equation and the momentum
balance equation. The derived shallow water equation is solved numerically using
a staggered finite volume method. In addition, the numerical scheme that is
constructed can be extended for varying topography (in this case it is called obstacle
in the downstream) and varying channel width case. To validate our numerical
schemes, the author compare the numerical results with the analytical solution and
the experimental data in (Mungkasi dkk., 2018). After obtaining good agreement,
the author also made comparisons with experimental data on dambreak flow through
the obstacle-trapezoid, triangle, and the cross-sectional width that experienced
contractions. Moreover, we can claim that the scheme can be used to investigate
cases for various topographies and various downstream channel contractions.
Further, the author concludes that the height of the obstacle is the most influencing
factor on the water level downstream and the position of the channel contraction
and the obstacle has no significant effect on the water level downstream. |
