Application of a new river classification scheme to Australia's tropical rivers
A revised typology of Australian tropical rivers was applied to the complete channel network (named and major rivers) shown on 1:250 000 topographic maps for three large drainage basins in northern Australia (Daly River, NT; Fitzroy River, WA; Flinders River, Qld). Reach mapping and classification were conducted using the revised typology. The 12 major river types proposed were: (1) bedrock rivers; (2) bedrock‐confined and ‐constrained rivers; (3…
Water, Wind, Wood, and Trees
Recent Australian research has quantified the role of large wood (wood of any origin and length with a diameter greater than 0.1 m) in dissipating stream energy, forming pool habitats by local bed scour, protecting river banks from erosion, and damming rivers with long rafts causing avulsions. Large wood in Australian streams is sourced by a range of processes from the nearby riparian zone which has usually been degraded by post‐European settleme…
Geomorphic Controls on Historical Channel Planform Changes on the Lower Pages River, Hunter Valley, Australia
Historical planform changes in a 14.7 km reach of the lower Pages River were determined to assess whether they were autogenic (inherent in the river regime) or allogenic (driven by external changes) in nature so as to better focus river management activities and river restoration works. A pattern metamorphosis or complete change in river morphology occurred during the February 1955 flood. The peak discharge of this event exceeded the slope and gr…
Assessment of Riparian Revegetation Trials on In‐Channel Benches in the Hunter Valley of Southeast Australia
Large‐scale river training works have been carried out in the Hunter valley since 1955 in response to flood‐driven channel changes. Vegetation was planted on in‐channel benches induced by river training works to consolidate the deposits and to increase channel boundary roughness. Exotic species of vegetation such as willows and poplars were previously used. In 1983, ten trial sites were planted with various species of native vegetation. Survival …

Further assessment of flood‐ and drought‐dominated regimes in south‐eastern Australia
Kirkup et al. (1998) [Australian Geographer 29, pp. 241–55] criticise our theory of alternating flood regimes and question its application to river management. A brief but critical appraisal of their work shows many errors and misrepresentations. When these are corrected, their challenge is found deficient
Development of the middle creek delta plain, Narrabeen Lagoon, NSW
Middle Creek drains 26 per cent of the total Narrabeen Lagoon catchment and has formed a 1.6 km‐long delta plain where the channel debouches into the coastal lake. The upper delta plain is characterised solely by fluvial landforms because reworking by lateral migration, cutoffs, channel widening and floodplain stripping has totally eroded the previously existing delta landforms. A combination of lateral and vertical accretion has formed a floodpl…
Morphological Impacts and Implications of a Trial Release on the Wingecarribee River, New South Wales
A trial, monitored release on the Wingecarribee River over 27 days had a peak discharge below the Wingecarribee Dam of 1090 ML/d, which had a flow duration of 0.95 per cent. Morphological impacts on 29 km of channel below the dam included bank erosion, concentrated neck overflow, bed degradation and channel widening at recent cutoffs, sedimentation in weir pools and overbank flow, particularly at discharges greater than 800 ML/d. Prolonged operat…
Hydrological impacts of flow regulation associated with the Upper Nepean water supply scheme, NSW
The upper Nepean River has been progressively regulated for water supply to Sydney and Wollongong since 1886 by the Upper Nepean Water Supply Scheme which consists of four large dams, two small dams and two diversion weirs. Secular rainfall changes produced periods of high rainfall and large floods (flood‐dominated regimes) between 1857 and 1900 and 1947 and the present, and an intervening period (1901–46) of low rainfall and small floods (drough…
Late quaternary alluvial history of Nowlands Creek, Hunter Valley, NSW
The valley‐fill sequence of Nowlands Creek, a 5.5 km2 basin in the Central Lowlands of the Hunter Valley, is characterised by three inset river terraces whose sediments contain either Aboriginal or European artefacts. The highest and oldest terrace is characterised by a well‐developed yellow duplex soil with Aboriginal artefacts in the A horizon. Deposition of the bulk of the terrace sediments occurred before 11 400 yrs BP when Nowlands Creek was…
Hydrogeomorphic Effects of River Training Works
Since 1955 the NSW Department of Water Resources has undertaken extensive river training works on many NSW streams. In the Hunter Valley alone over $23 million have been spent and more than 850 km of channel have been treated Published work suggests that river training works are usually undertaken in response to a pre‐existing problem of river instability but can also induce adverse hydrogeomorphic effects. One of the treated streams, the Allyn R…
River metamorphosis and environmental change in the Macdonald Valley, New South Wales, since 1949
A significant metamorphosis of channel form occurred on the lower Macdonald River between 1949 and 1955; width and width‐depth ratio increased and depth, sinuosity and weighted mean per cent silt‐clay in the channel perimeter decreased. The channel has remained unstable since 1955, exhibiting frequent variations in bed elevation and a recent period of minor channel contraction followed by slight enlargement. Since 1946 there has been an increase …
Potential impacts of sand and gravel extraction on the Hunter River, New South Wales
A number of investigations have been undertaken by the New South Wales Water Resources Commission to determine the regional and compound effects of large scale extractive industries on the stability of the Hunter River, New South Wales. Sedimentologic studies of bed material suggest that the Hunter River upstream of Denman has an armoured gravel bed that is immobile during regulated releases from Glenbawn Dam but is disrupted by moderate but less…
Rainfall, floods and river channel changes in the upper Hunter
Since 1946, there has been a significant increase in annual rainfall in the Hunter Valley, especially for stations in the western sector. Contemporaneous increases in rainfall intensities of frequent storms and flood peaks have also been recorded. From analyses of the data, together with a review of recent environmental changes in the Hunter Valley, it is concluded that human disturbance of the catchment has played no significant part in the incr…
