摘要
•A 3-D numerical model has been developed to simulate dam-break flows over uneven beds.•The model adopts an explicit finite-volume method based on collocated mesh that fits on solid boundaries.•The application of the model revealed the robustness and accuracy of the model.•Comparisons with depth averaged 2-D and other 3-D models, available in the literature, have been presented.•Application of the model on large computational domains can be computationally expensive.
