15 Risk-Informed Decision Making
Fig. 15.3 Dam 2 centerline cross section built in one raise, height 15 m
Fig. 15.4 Dam 3 upstream berms on starter berm cross section, total height 30 m at the moment
of the analysis
Piezometric surface at bedrock downstream of dam, at water level upstream. No
movements detected to date.
Dam 3 is an upstream structure (Fig. 15.4) constituted by a compacted till starter
berm on which upstream compacted waste rock berms have been built.
The piezometric level follows dotted blue line. Inclinometers have shown 15 mm
deformation within layer 4, between bedrock (stable) and surface.
Finally, Dam 4 was introduced in Sect. 11.1.2. It is an upstream dam of obsolete
design similar to recently failed dams. Details were shown in the referenced section,
and drawings are not available for confidentiality reasons.
