Oedometer tests were carried out on a silt used in flood embankment construction in Indonesia. Three test series were carried out under dry-of-optimum, wet-of-optimum and prepared wet and then dried, initial conditions. Where collapse was observed, the collapse potential for the specimen was evaluated and severity of collapse determined. This material has been sampled from embankments in East Java, Indonesia where there is a recurrent history of geotechnical failures. These preliminary results show the importance of good compaction control at the site and help to explain some failures observed at the site.

The Great Barrier Reef (GBR) Water Quality Plan outlines a clear set of water quality and management practice targets (50% reduction in nutrients and photosystem II (PSII) herbicides by 2013, 20% reduction in TSS by 2020). Five lines of evidence have been used to report on progress towards reef plan targets due to investment into improved agricultural management practices. This paper provides an overview of the results from one line of evidence, catchment modelling.
