Recognition of dryland fluvial, aeolian and lacustrine deposits has significant implications for reducing the risk of predicting reservoir and seal connectivity, and hence potential productivity. Dryland sedimentology is understudied compared to humid environments, and there are still many depositional element processes, geometries and architecture that have not yet been described from modern environments. The RARG has a long history of researching modern analogues of the Lake Eyre Basin, initially funded through three industry consortia (the Lake Eyre Basin Analogues Research Group) which ended in 2010. Studies of the sediments preserved in the modern settings of the dryland Lake Eyre Basin contribute to understanding the three-dimensional stratigraphic record better, and to better interpretation of the subsurface. The main focus of research has been on dryland fluvial sedimentology, and on the deposits of fluvial terminations around the Lake Eyre playa. Recent research localities include the fluvial sedimentology of the Neales River (western Lake Eyre Basin) and delta/terminal-splay deposits within ephemeral Lake Yamma Yamma (Cooper Creek, eastern Lake Eyre Basin).
