A range of previous studies have looked at land along the flood plain of the River Murray. The most detailed was by Hollingsworth, I D (1989) who undertook a reconnaissance soil survey of the Chowilla Anabranch System of the River Murray.
Several previous reports have generally described the flood plain areas relevant to this study. The suitability of the River terraces to flood irrigation was described by Baker and Potter (1968) who split the terraces into four main units including sandy areas, dissected areas, flat lower terrace and flat higher terrace.
Potter, Wetherby and Chittleborough (1973) mapped land systems of the Northern Murray Mallee. They described the flood plain as a separate River Terrace Unit consisting of dissected areas, lignum flats, high terraces and sandhills and stranded sand-bars. No attempt was made to map individual facets.
The studies of the Chowilla flood plain by Overton and Jolly (2004) indicated how the soil information from this survey would be used and the ground water/ soil survey baseline done along the River Murray floodplain provided some background information relevant to this survey area.
Brian Hughes (Rural Solutions SA) undertook reconnaissance soil survey and land unit mapping of the Floodplains of the River Murray, Woolenook Bend, Mundik Creek and Pike River area (2003), for DEH. Attempts have been made to correlate the land units of this survey with that of Hughes.
The intent of this study was to describe the flood plain areas of the Eckert island section of the Katarapko National Park. The focus is on understanding and describing soils which were evident in various mapping units. The soil survey was undertaken at a reconnaissance level which gave an indication of soils but was a not a comprehensive assessment. The principal use of this report is as a basis for modelling by CSIRO to help determine flooding regimes applicable in these flood plain areas. [Click here to download the full report]
