|Several former courses of the major rivers, such as the Murray and Goulburn, are marked by extensive meander belts and source-bordering dunes, often with associated Red Gum forests, and occur in shallow depressions below the plains, such as the Gunbower Forest. Commonly these have associated Re gum forests in shallow depressions below the plains, such as the Gunbower Forest, or on broad, occasionally inundated fans such as the Loddon Fan. These younger incised channels were formerly referred to as ancestral rivers (Pels, 1964b). |
Extensive meander belts and source-bordering dunes that occur in a broad swale north of Warracknabeal note a former course of the Yarriambiack River. These younger incised channels were formerly referred to as ancestral rivers (Pels 1964b).
Soils vary on these plains where regolith consisting of sands, loams and clays have accumulated. The major soils include sodic, grey texture contrast soils (grey Sodosols) and cracking clay soils (Vertosols).
