| Outline of Final Research Achievements |
Researches on failure process of glacial lake morain dam, landslide dam, and river dykes due to overtopping of water, etc. have been investigated through the physical model experiments and numerical simulation using integrated model newly developed. The field assessment of the real glacial lake in Nepal has been studied and the impact of climate change on this glacial lake has been discussed. The numerical modeling of erosion process of dam (dyke) body made by non-cohesive fine sediment was investigated with the results of flume experiments. In this research, the model was verified using some results of laboratory experiments. The numerical results of temporal variations of moisture profile inside the dam body, dam surface erosion, and the deposition behind the dam were found to be consistent with the experimental results. Water and sediment discharges outflowing due to dam breach were simulated and the results were fairly well agreed with experimental ones.
