Dryland salinity occurrence in the medium sized Broadford Salinity Province is largely driven by groundwater seepage at ‘break-of-slope’ and near drainage lines. Coming from local to intermediate scale Groundwater Flow Systems, mapped discharge areas are mostly small, ranging from under 1 ha up to 46 ha. The impacts are mainly waterlogging damage to soil, with moderate salt concentration at the surface limiting productivity of pastures and crops. Salt loads to surface water were also of concern from this province and serious soil erosion has occurred at some sites. |
