Modeling lateral enlargement in a dam breach includes a vertical cut at the slope toe due to erosion, an approach to determining the critical slip surface, the effective and total stress methods dealing with different dam materials.
- •
Spreadsheet DBS-IWHR coded in Excel with VBA programming allows practitioners to work on a transparent and self-explanatory environment, ready for secondary development on a group-sourcing basis.
