The medium sized Springhurst Salinity Province partly overlaps the Ovens Riverine Plain to the west and small foothills composed of Permian age glacial sediments, Ordovician metamorphic rocks and Devonian granite to the east.
Local scale Groundwater Flow Systems (GFSs) in the weathered granites, Permian glacial rocks and alluvial/colluvial fans dominate and drive salinisation processes, which have been a problem in the area since at least the 1970s. Salinised land developed in the valley floors, at the ‘break-of-slope’ within the local foothills and on the foot slopes at the edge of the Riverine Plain.
Salinity management options for this province include planting trees at the ‘break-of-slope’ and along changes in soil texture, and the establishment of perennial pasture across the mid and lower slope areas.
