Title: | Bank instability along a weir pool of the River Murray | Contributor(s): | Thoms, Martin (author) | Publication Date: | 2017 | DOI: | 10.1080/03721426.2017.1374158 | Handle Link: | https://hdl.handle.net/1959.11/22233 | Abstract: | River banks are an important transition zone between aquatic and terrestrial environments. This ecotone is highly vulnerable to natural and anthropogenic disturbances. Bank erosion is a common occurrence along the River Murray. Morphological features reflecting river bank instability form a near-continuous pattern along large tracts of the river. This study investigates the character and extent of bank instability along the Torrumbarry Weir Pool. Over 90% of the bank length in this weir pool was assessed as being actively eroding. Notch development was the dominant instability mechanism and it promoted other forms of bank instability. Erosion notches result from stable water levels and inherent soil instability of the river banks along the weir pool. The character and extent of river bank erosion recorded along this section of the River Murray is an artefact of flow regulation and not a reflection of the natural occurrence of bank erosion in river networks. Water level management in the upstream weir pool has significant implications for the management of river banks along regulated reaches of the River Murray. | Publication Type: | Journal Article | Source of Publication: | Transactions of the Royal Society of South Australia, 141(2), p. 151-168 | Publisher: | Taylor & Francis Australasia | Place of Publication: | Australia | ISSN: | 2204-0293 0372-1426 |
