Dryland salinity occurrence in the small Whiteheads Creek Salinity Province mostly relates to ‘break-of-slope’ and drainage line groundwater discharge from local to intermediate scale Groundwater Flow Systems. Mapped discharge areas are relatively small (only up to 12 ha) and have caused waterlogging, moderate soil salinity increases and a significant rise in the salinity of Whiteheads Creek. Losses have mainly been to grazing land, with the spread of Spiny Rush in some places. |
