Experimental investigation of accelerated low water corrosion of steel piling in harbours

Accelerated Low Water Corrosion (ALWC) of steel piling used for port infrastructure such as wharves and bridge and jetty supports has become a topic of much concern. A review of the problem is given and a recent research project that examines the influence of bacteria and nutrients on corrosion is described. It is shown that evidence of ALWC is available after only a few years of exposure and is correlated with water (nutrient) pollution.
