Factors influencing phreatic surface location for upstream embankments: (a) effect of
pond water location; (b) effect of beach grain-size segregation and lateral permeability
variation; (c) effect of foundation permeability; (d) effect of decreasing tailings perme-
ability with depth; (e) effect of slimes layers; (f ) effect of underdrains if there are no lay-
ers of slimes. Starter dams not shown in (a) to (e).

.
Some features of these arrangements are:
Ring dike
-suitable for flat terrain;
- no runoff from external catchments;
