Fluvial geomorphology and riverine processes
Fluvial depositional sequences such as alluvial floodplains and terraces are significant features in the geomorphic development of inland channel systems. Floodplain morphology and chronology provide critical insights to the history of a river's development. The drainage of Australian streams since European settlement has resulted in widespread incision, with catastrophic widening leading to increases in sediment yield. In eastern Australia alone, it affects in excess of 50,000 km of valley floor streams. This has left many streams entirely isolated from their floodplains, resulting in the loss of geomorphic complexity. With impacts on stream health, riparian function and water flows, understanding fundamental fluvial forms and processes for sustainable landscapes is crucial.
