“…The distribution and some aspects of the genesis of the ferruginous red and yellow earths in Tropical Queensland have been discussed and summarized by Isbell and Field (1977) and more recently by Coventry and co-workers (Coventry, 1979;Coventry et aZ., 19&3;Coventry and Williams, 1984). These workers consider many of these soils to be relict (Coventry, 1979) and formed under climatic conditions different from those in which they are now found.…”

“…These workers consider many of these soils to be relict (Coventry, 1979) and formed under climatic conditions different from those in which they are now found. In contrast, there are also pedological and hydrological data (Coventry and Williams, 1984) to suggest that the red and yellow earths also have different contemporary hydrological regimes which would explain the color differences between these two groups of soils.…”

“…Consider first contemporary processes. From detailed measurements of the currently active soil hydrological regimes in red-yellow-grey soil sequences from Australia (Coventry and Williams, 1984) and North America (Daniels et aZ., 1975) a strong relationship has been shown between the particular hydrological regimes currently active in the profiles and a number of morphological features, such as color and depth to the upper limits of the various colored mottles. 13-7, in both southern Africa (Fitzpatrick, 1974; Table 13-0 and Australia; (ij) in "reversed toposequences" (hydrosequences) in parts of North Queensland, Australia (Coventry and Williams, 1984); and (iii) in going from red soils at the edge of highly-dissected plateaux to yellow-brown soils on the plateaux in parts of North East Victoria, Australia (this soil sequence is remarkably similar to the so-called "red edge effect" described by Daniels et aZ.…”

“…Fine grain sizes and laminations indicate a very low energy environment, and mottling is interpreted to result from periodic wetting (Coventry and Williams 1984). Stratigraphic variations in the frequencies of rhizoliths, slickensides, and mottling indicate that sedimentation was episodic, as might occur from very infrequent flooding.…”

There is a dearth of knowledge on the runoff processes of eucalypt woodland communities in the semi-arid tropics of Australia. The work was undertaken on a 100 m transect of a 0.8 degree hillslope typical of the 'smooth plainlands' of central-north Queensland. This paper introduces a new experimental design for measuring overland flow in such areas by way of a cascade system of unbounded runoff plots which allow the inputs and outputs between troughs to be calculated. Most storms generate overland flow. Time to overland flow ranges between 1 and 18 min where rain intensities are above 10mm hr-' and when the average detention storage of 3.6mm is exceeded. The bare soil surfaces within the scattered grass understory control the runoff generation process through the temporal variability of field saturated hydraulic conductivity. The study demonstrated that overland flow is mainly redistributed over the freely-draining oxic soil. Some areas export more overland flow than they gain from upslope (runoff), others gain more overland flow than they export (runon). Over the study period only 2 per cent of total rain is transferred out of this 100m transect as overland flow due to the short duration of storms, the relatively high soil permeability, and the low slope angle. The remainder adds to the large soil water store or deep drainage. The variability of runoff-runon over these 'smooth plainlands' highlights how results from bounded plots would be misleading in such areas.
