Abstract: | Soils will behave differently when used for agriculture, forestry, and other purposes and must be managed differently. The
difference is most evident in the Inverbrackie Creek catchment area in South Australia where the study reported in this article
was conducted and where the soils are used extensively for grazing and dairy farming. This catchment covers an area of 8.38
km2, comprising an undulating upland plain with irregularly high hills and broad interfluves.
Previous information-gathering methods used to model the catchment's hydrologic activity have been derived from the downstream
pluviographic point-source technique. The model input samples obtained by this technique are not truly representative of the
catchment. The potential for using remote sensing color infrared imagery to delineate the areas contributing to soil sediment
flow is demonstrated as a better alternative to obtaining representative samples to model this activity.
