About the report

Part 1: Channel stability in a sand-bed stream in the seasonally wet tropics, Paper presented at 10th Australia New Zealand Geomorphology Group (ANZGG) conference, Kalgoorlie, Western Australia, 30 September–4 October 2000.

Swift Creek (Ngarradj) is a sand bed stream in Kakadu National Park, Northern Territory. The stream, located in the seasonally wet tropics, flows for approximately half of the year during and immediately after the wet season. In 1998, 51 permanently marked cross sections were installed to monitor the amount of bed sediment storage and/or large scale erosion at three gauging stations. These cross sections have been surveyed annually during each dry season since installation. These survey data provide information about the changes in sediment storage that have occurred between each dry season. Between 1998 and 1999, aggradation of between 0.1 and 0.2 m occurred at each of the three sites but between 1999 and 2000, this sand level remained constant.

Part 2: Channel morphodynamics of a sand-bed stream in the seasonally wet tropics of Australia, Paper and Poster presented at International Association of Hydrological Sciences (IAHS) conference, Alice Springs, 2–6 September 2002.

The following is an abstract that was submitted for presentation at the International Association of Hydrological Sciences (IAHS) conference held in Alice Springs September 2002. The conference had a theme of “The structure, function and management implications of fluvial sedimentary systems”. The paper was not accepted for an oral presentation however it was accepted for a poster session for which a four page paper was required. The paper was published in a supplementary booklet to the main conference proceedings.
