The Pittong Salinity Province is the smallest of the provinces in the Corangamite catchment and has a deeply weathered granite profile on a gently undulating terrain. The deep granite regolith produced local Groundwater Flow Systems that have slow groundwater movement. The increased recharge that followed land clearing caused groundwater levels to rise, which lead to increased discharge along many of the drainage lines and valley floors and the subsequent waterlogging and salinisation of soils. |
