One of the largest known megafloods on earth resulted from a glacier dam-break,which occurred during the Late Quaternary in the Altai Mountains in Southern *** modeling is one of the viable approaches to enhancing the understanding of the flood *** computational domain of this flood is over 9460 km2 and about 3.784 × 106 cells are involved as a 50 m × 50 m mesh is used,which necessitates a computationally efficient *** the Open MP(Open Multiprocessing) technique is adopted to parallelize the code of a coupled 2D hydrodynamic and sediment transport *** is shown that the computational efficiency is enhanced by over 80% due to the *** floods over both fixed and mobile beds are well reproduced with specified discharge hydrographs at the dam ***,backwater effects during the flood are resolved at the bifurcation between the Chuja and Katun ***,the computed maximum stage and thalweg are physically consistent with the field data of the bars and *** effects of sediment transport and morphological evolution on the flood are *** analyses indicate that the impact of the peak discharge is significant,whilst those of the Manningroughness,medium sediment size and shape of the inlet discharge hydrograph are marginal.
