ABSTRACT The initial stages of instantaneous dam-break waves are here evaluated spatially and temporally through 36 physical experiments. Different conditions were tested for downstream (J) upstream (M) water depths their ratios (r) to approach realistic prototype dams. Two non-dimensional parameters proposed – effective height (HEF) velocity (VEF) evaluate peaks along the wave evolution. maxim...

South32 Worsley Alumina Pty Ltd operates several bauxite residue storage facilities at their refinery in Western Australia. The slurry is thickened and pumped onto the which are constructed on an upstream basis using compacted earthfill embankments. BRDA 5 newest of facilities, established 1999, has a current maximum height embankment slope 42 m, starter makes up first 22 m. Since 2010, been tr...

The paper describes the implementation of stress dependent boundary conditions in the FEMTOOL code developed for numerical solution of coupled problems. Moving interface flows including breaking waves are considered. The performance of the numerical technique is validated by solving the dam break problem in the confined domain. The code development issues and the detailed investigation of param...

Abstract When a reservoir is damaged, it will bring destruction to people's lives and the regional economy. Flood simulation risk assessment are two effective ways mitigate flood risk. assessed by using hazard vulnerability indices. However, one of key concerns how quantify hazards vulnerabilities more rationally. To this end, study introduces new quantitative method for assessment. Three schem...
