Site effects are resulted from the non-linear filtering mechanisms within the soil sedimentary layers overlying bedrock. In contemporary design codes, site effects are taken into account by introducing different site factors for different site classes. The prescribed site classification systems are based on averaging shear wave velocity in the soil sediments. However, significant amplification of the seismic displacement demand may be developed from mechanisms which can result in resonance behaviour. In such situations, soil amplification cannot be determined accurately by considering the average shear wave velocity of the sediments alone. The effects of vertical heterogeneity in the soil sediments have …

In recent years, there has been considerable research effort focusing on the removal of specific individual contaminants at trace level concentrations instead of the traditional surrogate, and often ill-defined, water quality indicators. The need for this more precise water quality characterisation has been driven by stricter environmental regulations and legislation, and the increasing need to utilise non-traditional water resources including reclaimed municipal wastewaters. Amongst several advanced technologies used for high quality water treatment, removal of trace contaminants by nanofiltration membranes has been investigated to a considerable extent. However, it is known that such membrane filtration processes tend not to operate …
