Abstract
In the region of drought-dominated inland eastern Australia now known as the MurrayDarling
Basin, floods occupy a special status. Although relatively infrequent, they are
crucial sources of water for people, animals, and plants. They drive hydrology in the
region, supplying most of the surface and ground water. Floods are often transformative
events for people as well as the non-human environment. This thesis explores Australian
settlers' changing relationships with, and understandings of, the rivers and floodplains of
the Murray and Darling river systems from 1850 to the present. It analyses floods in terms
of the two dominant roles that they have played in settler history in the Murray and
Darling river systems: as 'natural disasters' and as part of the wider hydrology of rivers.
Four key flood events are closely examined. The selected flood episodes - 1852, 1890,
1956, and 1990 - . illuminate changing ways of knowing and managing rivers, floods, and
floodplains over a century and a half, and some of the long-term consequences for people,
rivers, and ecologies. Analysis is also anchored in an examination of a number of themes:
regional tension with centralised governments over decision-making processes; the
particular forms of river management that centralised government enables (such as largescale
riverine engineering); different kinds of knowledge of the rivers, especially regional
(or local) knowledge, scientific knowledge, and government (and managerial) knowledge;
tensions and cooperation between the custodians of these different kinds of
understanding; and the emergence of the Murray-Darling Basin as a managerial unit. The
thesis aims to present a 'floods-eye-view' of the history of the area (and, partly, of
Australia) and explore the ways that settlers, the rivers, and the floods have re-made each
other.
