Abstract

The dam-break problem is important in the design and management of hydraulic engineering. In order to study the spread of dam-break flow on complicated terrain, three-dimensional numerical simulations of the dam-break flow were carried out using VOF in this paper. The results are agreement with experimental data. The complex flow characteristics flood wave propagation process of three-dimensional dam-break flood are demonstrated, which provides scientific basis for the analysis and prevention of disaster caused by dam destruction.
