Effects of toe configuration on throughflow properties of rockfill dams [PDF]
Rockfill dams must be equipped with defence mechanisms to counteract the destabilizing effects of throughflow forces under accidental leakage scenarios. A key component of the rockfill dam overtopping system is the rockfill dam toe, constructed in tandem

Hydraulic and structural evaluation of rockfill dam behavior when exposed to throughflow and overtopping scenarios [PDF]
Dams are vulnerable to extreme flood events in turn leading to accidental overtopping. This inparticular applies to rockfill dams comprised of pervious and erodible material.
