This paper presents the results of an extensive laboratory set tests aimed to study failure downstream shoulder highly permeable rockfill subjected overflow. The experimental research comprised testing 114 physical models by varying following elements: (i) median size uniform gravels (7 45 mm); (ii) configuration dam, i.e., upstream and shoulders crest or just shoulder; (iii) dam height (from 0...

The rockfill toe structure situated within the downstream slope of dams is an integral part a defense mechanism safeguarding dam in throughflow situations. Recent studies have concluded that can significant impacts on development and stability under scenarios accidental caused by overtopping core. ability to numerically model effect various configurations flow through support design effective d...
