Acid sulfate soils in the Murray–Darling Basin

Record low inflows and river levels in recent years have led to the drying of many wetlands in the Murray–Darling Basin (MDB). In some cases this resulted in the exposure of acid sulfate soil materials. This report summarises the major findings and key outcomes from the Murray-Darling Basin Acid Sulfate Soils Risk Assessment project. Using a tiered assessment approach, wetlands were screened through a desktop assessment stage, followed by a rapid on-ground appraisal, and then detailed on-ground assessment if results of previous stages indicated an increased likelihood of occurrence of acid sulfate soils.
