TL;DR: In this article, the influence of hydraulic conditions on the spatial distribution of macroinvertebrate assemblages was investigated in three riffles in a perennial Australian river and the biological significance of directly measured and complex hydraulic variables was determined by a combination of univariate and multivariate statistical procedures.

TL;DR: In this article, a six stage model is proposed for the sequential development of floodplains on the Waimakariri River from: (i) active river bed; (ii) stabilizing bar; (iii) incipient floodplain, established floodplain; (iv) mature floodplain and to (vi) terrace

TL;DR: In this article, the authors used Digital Elevation Models (DEMs) coupled with catchment area based discharge estimation techniques to model downstream trends in channel gradient, total stream power, and in riverscapes conducive to regime analysis, also specific stream power.

TL;DR: The results demonstrate the importance of accounting for autocorrelation inherent in telemetry data, and for developing management strategies that are more robust to the effect of future climate trends on estuarine fish populations, in response to selected environmental variables using an acoustic telemetry array in south-eastern Australia.

TL;DR: In this article, the migratory response and behaviour of catadromous Australian bass with regard to hourly mean river flows and water temperatures was assessed over 15 months, using a 75-km passive acoustic telemetry array in the regulated Shoalhaven River below Tallowa Dam.
