โœฆ Synopsis

The distribution of soil I3'Cs in relation to selected soil and landform properties was studied across a 16 ha hillslope hollow in the Hunter valley, New South Wales, Australia. The hillslope was used as grazing for cattle. Caesium-137 was not significantly related to the amount of sand, silt, or clay, the bulk density, the organic matter content, the slope angle or the relative distance downslope. However, '37Cs was significantly related to the thickness of the soil A horizon. Spatial variations in I3'Cs were compared with topographic units and a six-element hillslope model, but there was little correspondence. It was thought that the effects of microtopography could have masked potential interrelationships between I3'Cs and broader scale landform parameters.

## Measurements are reported of the distribution of "'Cs within a 6.6 ha drainage basin on cultivated black earth soils located near Merriwa in New South Wales (N.S.W.). The results were used to estimate net loss as well as accumulation of soil. The losses of "'Cs from the catchment slopes were as
