... resistance was also used to evaluate the relative density and the modulus of sandfill using empirical correlations derived from in-situ density tests and conepressuremeter tests. The predicted relative density of sand from the cone resistance was found to be agree reasonably with the direct density...

By means of statistical analysis of the data, good correlations between slope failure rate, maximum 24-hour rainfall and slope information have been established for soil cut slopes for a pilot study area. The correlations have been used to estimate the expected number of landslides...

For TCE and toluene the batch tests give distribution coefficients that are two orders of magnitude greater than would be estimated from organic carbon, and one order of magnitude greater than from column tests. Some of the factors that could...

This allows for the generation of multiple data streams enabling cross correlation resulting in increased levels of confidence in the final assessments. The different survey configurations will be discussed indicating the benefits...
