近年来，人们越来越重视污染水道的特征和修复。通常一段很长的河流和相关的终端河口在几十年的时间里已经被工业污染了。这些工业释放的有毒物质逐渐被埋在沉积物中，因此沉积物中这些物质的概况成为污染过程的记录。这些水系可能只有零碎的深度调查历史，或者根本没有。这样的水系需要另一种方法来测量沉积速率，并确定与埋藏有毒物质有关的日历日期。
In recent years there has been a growing emphasis on characterisation and remediation of contaminated waterways. Often a long stretch of river and the associated terminal estuary has been contaminated by industries over a period of decades. The toxic substances released by these industries become progressively buried in the sediments, such that profiles of these substances in the sediment become a record of the contamination process. These water systems may have only a fragmentary history of depth surveys, or none at all. Such water systems require another method to measure sedimentation rates and to determine the calendar dates associated with buried toxic substances.
