Slough Ring Salinity

This type of salinity occurs as a ring of salt immediately adjacent to a permanent water body. Water infiltrates from the pond into the permeable upper soil layer and moves laterally upslope as shallow groundwater in an unsaturated state through this layer. The water may also flow downward, raising the water table. Water from the lateral unsaturated flow and capillary rise from the water table emerges at the surface where it evaporates, leaving salts at the edge of the slough. This type is very common in Central Alberta and less in the southern part of the province.
